All You Need to Know about Ball Bearings in India
Ball bearings are commonly used in construction sites, industrial areas, etc. It is a circular joint that connects the rotating part of a machine to its other parts, mostly the stationary ones.
Ball bearings are an indispensable part of various machinery. So, people may have to buy it more often. However, before buying, one needs to know all details related to it. This article talks about the types of ball bearings, their uses, and their selection criteria.
Types of Ball Bearings in India
Ball bearings are named according to their physical design. Depending on the specific purposes, one can select the type and such types are:
- Deep groove
- Angular contact
- Thrust (single-row and double-row)
- Self-aligning
Besides, there are two other types namely, Y bearings and Thin-section bearings.
Deep Groove Ball Bearings:
The grooves are cut more deeply than some alternatives in deep groove ball bearings. Being fully surrounded, they come with more wall-surface. Against it, they can roll and transfer loads in more diverse directions.
It is suitable for bearing axial loads from both the right and left directions. Also, it helps to bear radial loads. When they carry both types simultaneously, they are called radial-axial bearings.
Angular Contact Ball Bearings:
These ball bearings have asymmetrical grooves in which one groove wall is longer than the other. Its two subcategories include double row and single row.
As their name suggests, single-row ball bearings come with a single row of balls. On the other hand, double-row bearings have two rows of balls separated by a long inner wall.
Thrust Ball Bearings:
In such ball bearings, the grooves do not extend to cover enough portion of the balls' tops and bottoms. Hence, it cannot support heavy radial loads. Moreover, these bearings may collapse if excessive force is exerted.
This category is also of two types- single row and double row. A single-row thrust bearing ball bearing is suitable for applications with axial loads in one direction.
Self-aligning Ball Bearings:
These ball bearings come with two rows of balls which provide two rows of contact points against the races' grooves. Such ball bearings are commonly used when a perfect right angle between the shaft and the bearings is not found. Sometimes, it happens due to installation conditions.
Y-bearings are ball bearings that have an extra-long inner race. They extend like a short pipe out of the bearing's sides.
Thin-section bearings come with thin races, smaller ball sizes and narrower grooves. The decreased width and ball size require less material. Hence, it ensures lower operating costs than usual.
Uses of Ball Bearings:
Ball bearings are used in various applications, particularly in devices with engines or rotation mechanisms. Some examples of such ball bearings are:
Agricultural sector: It is often used in the rotating parts of tractors, ploughs, and other equipment.
Construction: From cranes and excavators to compactors and other machines, ball bearings are used in diverse applications in the construction sector.
Centrifugal pumps: It is also used in the rotating shaft near the pump's engine output and fan input.
Household items: One can see ball bearings in household items like bicycles, food processors, hair dryers, and other tools.
Office spaces: Hard drives, fans, fax machines, etc. - the list is long. Thus, ball bearings are used in many applications in office spaces.
Electric motors and gearboxes: Ball bearings support the rotating output shaft in electrical motors. Also, it provides support to gear shafts and input and output shafts in gearboxes.
How to Select the Right Ball Bearings in 2023
If one goes to select the right ball bearing, there are a few things one needs to keep in mind. First, one must check the machine's official references for ball bearings. It will help to find a bearing recommended by the experts who made the machines.
One must focus on a few essential factors if, however, such references are unavailable. They are:
Expected direction and amount of load:
While selecting a ball bearing, one should learn how much operating load is expected. Also, the buyer should learn about the load's expected direction. The standard inner and outer race bearings can be used for radial loads. And for axial loads, a thrust bearing is the ideal option.
Right inner and outer diameter:
One must ensure that the outer diameter fits well into the machine's housing. And the inner diameter should provide a shrink fit and clench the shaft tightly through it.
Bearing material:
One must choose the material depending on the dynamic loading capacity and operating environment. Everything else remains equal in this matter.
Average Speed:
One can learn at which average speed the bearings will operate by checking the machine's dimensions and production rate.
Sealed or open:
It is another vital factor to look at. One should select a sealed, shielded, or open bearing based on a few things. They are the operating environment, accessibility, and initial cost of the ball bearings.
For environments with heavy debris, one should use sealed or shielded bearings. One can use open bearings for environments with low debris.
Besides these, there are other factors like shaft alignment, the width of the races, and so on.

There are many types of concrete admixtures available for different types of requirements. One of the most common applications of admixtures is to improve the strength of concrete structures, making them ideal for small-scale and large-scale projects.
Types of Admixtures Used in Concrete to Enhance Strength
Depending on the type of project, there are five different admixtures that can be used in concrete to increase strength.
1. Pozzolanic Admixtures
When mixed with cement, Pozzolanic admixtures react with calcium hydroxide to form additional compounds that fill in the gaps between cement particles, resulting in denser and more durable concrete with increased compressive strength. This makes pozzolanic admixtures ideal for load-bearing applications and large structures like dams. Fly ash and silica fume are commonly used Pozzolanic admixtures.
2. Superplasticizers
Superplasticizers are used to increase the workability of concrete without having to add additional water. This helps to shape and form the concrete with minimal addition of water, which would otherwise weaken the concrete.
Superplasticizers can be used in a variety of concrete applications, including high-strength concrete, self-consolidating concrete, and shotcrete. They can also be used to reduce the amount of water needed in the concrete mixture, which can improve its strength and durability.
3. Water Reducers
Water reducers are used to reduce the amount of water needed in the concrete mixture. They work by dispersing the cement particles more effectively, which can lead to more compact and dense concrete with increased strength.
Water reducers can be used in a variety of concrete applications, including high-strength concrete, self-consolidating concrete, and shotcrete. They can also be used to reduce the risk of shrinkage and cracking in concrete by reducing the amount of water in the mixture.
4. Accelerators
Accelerators are used to speed up the setting time of concrete. Although these admixtures do not directly affect the strength, they enable the mix to cure properly, thereby improving the strength of the concrete. They work by increasing the rate of chemical reactions in the concrete, which can help it reach its full strength potential more quickly.
Accelerators can be useful in cold weather conditions, allowing the concrete to set quickly and attain its strength. However, they can also lead to increased shrinkage and cracking if used improperly. Therefore, it is advised to use these admixtures only when demanded by the application.
5. Retarders
Retarders are used to slow down the setting time of concrete, which can be useful in hot weather conditions. Rapid drying of concrete can result in cracking which eventually reduces the strength of the concrete.
Retarders reduce the risk of cracking and improve the strength and workability of the concrete. However, they can also lead to reduced early strength development if used improperly.
Although accelerators and retarders do not directly affect the strength of concrete, they improve the curing process of concrete, thereby ensuring the required strength.
Overall, the use of admixtures in concrete can be an effective way to increase its strength and durability, while minimizing the risk of cracking and defects. However, it's important to choose the right admixture for the specific application and to follow the manufacturer's instructions carefully to ensure proper use and optimal results.
Which One Should You Choose for Your Project
The choice of the right admixture to increase the strength of concrete depends on the requirements of your project. If your project requires enhanced strength with excellent resistance to cracking, it is advised to use Pozzolanic admixtures, whereas Superplasticizers and Water reducers are recommended if your project requires high density for good loadbearing capabilities. On the other hand, accelerators are used to improve the strength of the concrete when working in colder regions, and retarders are suitable for warmer regions.
Final Thoughts
Admixtures are excellent additives that can enhance the strength of the concrete. However, it is important to analyze your requirements before selecting the right admixture for your project. L&T-SuFin is the leading marketplace in India that provides a wide variety of admixtures that can be used to increase the strength of concrete for your project.

A Guide to Selecting the Best Admixture for Concrete
Admixtures play an important role in improving the properties of the concrete mix, thereby resulting in superior quality output. However, with so many admixtures available on the market, it is often difficult to select the right one for your project. This article provides a detailed guide on the best admixtures for concrete that are popularly used for construction projects in India.
Admixture and Its Types
Admixtures are chemical compounds that are added to concrete during the mixing process to modify its properties and improve its performance. These materials can be added in small quantities and can have a significant impact on the properties of the finished concrete.
There are many different types of admixtures that can be used in concrete, each with its own set of properties and benefits. Some common types of admixtures include:
- Water-reducing admixtures
- Superplasticizers
- Air-entraining admixtures
- Accelerating admixtures
- Retarding admixtures
- Corrosion Preventing Admixtures
- Bonding Admixtures
Five Best Admixtures for Concrete
Admixtures are used based on the requirement of the project. As a result, there is no single admixture that can prove to be the best for concrete in every project. However, some admixtures are commonly used, depending on the requirement of the project.
1. Best Admixture To Alter the Setting Time
Admixture can be used to alter the setting time of the concrete, i.e., either increase the setting time or decrease it. These admixtures are known as accelerators and retarders. Accelerators are used to speed up the setting time of concrete when working in colder regions. In contrast, retarders are preferable for hotter regions to avoid the quick setting of the concrete, allowing for a longer time to shape and finish the project.
Calcium chloride is one of the most commonly used accelerators, due to its easy availability and low cost. Apart from that, triethanolamine, silica fume, silica gel etc., are some other available accelerators. On the other hand, gypsum, common sugar, and salt are some of the commonly used retarders.
2. Best Admixture to Reduce Water Requirement
The workability of the concrete depends upon its softness, which generally increases with the increase in water content. However, increasing the water content beyond a certain limit can affect the strength and durability of the final project. To resolve this issue, you can add water-reducing admixtures, known as plasticizers. These admixtures are available in three types: standard plasticizers, mid-range plasticizers, and superplasticizers.
While standard plasticizers reduce the water requirement of concrete by 10%, mid-range plasticizers reduce it by 15%. On the other hand, superplasticizers reduce the water requirement by 30%. Therefore, adding plasticizers improves the workability of the concrete while improving its overall strength. Calcium and sodium are two of the commonly used plasticizers.
3. Best Admixture To Impart Waterproofing
Waterproofing admixtures generally consist of elements such as aluminium sulfate, zinc sulfate aluminium chloride, silicates, etc. These elements seal the pores of the concrete preventing the water from penetrating through it, which can cause cracks, corrosion, and weakening of the structure over time.
These admixtures are ideal for various projects such as making a concrete water tank or bathroom, where good waterproofing is of utmost importance. It must be noted that these admixtures also act as accelerators, thereby making it necessary to also add retarding admixtures if a slower setting time is desirable.
4. Best Admixture To Improve Durability
Air-entraining admixtures are used when enhanced durability is desirable in the project. These are relatively new admixtures, which when added to the concrete mixture, form tiny air bubbles which improve the workability of the mixture. Furthermore, the aerated mixture results in a lightweight structure with an improved modulus of elasticity, thereby improving the durability of the structure in freezing and thawing conditions. Some of the commonly used air-entering admixtures consist of Teepol, darex, vinsol resin, etc.
5. Best Admixture To Inhabit Corrosion
Corrosion-inhibiting admixtures (CIAs) are used in concrete to reduce the rate of corrosion of steel reinforcement. There are different types of CIAs available in the market, and the selection of the best one depends on various factors such as the severity of the corrosive environment, the type of reinforcement used, and the required service life of the concrete structure.
Calcium nitrite and Calcium nitrate are two of the most commonly used corrosion-inhibiting admixtures. While calcium nitrite is suitable for projects located in an alkaline environment, such as coastal regions, calcium nitrate is suitable for acidic environments.
Apart from these, there are various other types of admixtures that can be used based on your requirement. You can also mix multiple admixtures to impart the desired properties and improve the overall quality of the project.

AAC Blocks Vs Clay Bricks - What's the Difference?
Autoclaved Aerated Concrete blocks, abbreviated AAC blocks, are a type of masonry block that comprises a combination of lime, cement, water, quartz sand, and aluminum powder. These bricks are cured in a high-pressure chamber.
Like ordinary red bricks, also known as Clay Bricks, they too are used in the construction of walls, floors, and roofs and offer a host of benefits, both to builders and homeowners.
So, how do the two kinds of bricks differ from each other? In this article, we will understand the difference between ordinary red bricks and AAC blocks accounting for several parameters like Compressive Strength, Durability, Utility and Performance, Workability, and Sustainability.
Tabular Comparison Between Red Bricks and AAC Blocks
Refer to the table below for a quick and short comparison between red bricks and AAC blocks.
| Parameter/Property | Red Bricks | AAC Blocks |
| Compressive Strength | 2.5 to 3.5N/mm2 | Higher - 3 to 4.5N/mm2 |
| Durability | Less Durable | More durable due to uniform structure. |
| Utility/Performance | Heavy and Bulky | Thinner, Lightweight and so easy to use. |
| Workability | More labor costs are involved due to slower construction | Faster construction |
| Eco-Friendliness | Not eco-friendly as it uses topsoil. | Eco-friendly in nature as it utilizes leftover like flash. |
Comparing AAC Blocks with Red Bricks
Compressive Strength
Since AAC blocks are manufactured in specialised factories or high-pressure chambers known as claves, the material offers higher compressive strength than ordinary bricks.
AAC blocks provide 3 to 4.5N/mm2 of compressive strength, whereas for Reb Bricks, the value is lower and ranges from 2.5 to 3.5N/mm2.
Durability
When it comes it AAC blocks, they have a more uniform structure in comparison to red bricks, which makes the former more durable in nature, which in turn gives more strength to the entire structure. Rid Bricks are brittle which results in heavy wastage during construction.
Plus there are fewer repairs and maintenance involved when it comes to buildings made up of AAC which means builders, as well as developers, can increase the lifespan of the establishment/buildings with AAC.
Utility and Performance
Utility and performance-wise, AAC blocks offer enormous benefits compared to red or clay bricks.
AAC blocks are lightweight means they are easy to carry/use and are helpful especially for high-construction projects. They are also thinner offering more tensile strength which increases the overall carpet area of a project, which makes them effective especially for smaller area projects.
What's more? AAC blocks are fire resistant offering fire resistance for up to 4 hours, offer better sound insulation of about 42 dB, and have better thermal insulation properties resulting in (25-30)% heating-ventilation costs.
Besides, the AAC blocks are easy to store as they don't absorb much water compared to red bricks. In fact, they absorb a maximum of 10% water by weight and they are earthquake and pet resistant as well.
Workability
Workability implies how easy to handle the ACC blocks are and how easy it's to construct projects with them.
Since AAC is lighter than red bricks for the same volume and has better tensile strength, the material offers superior workability across all kinds of construction projects plus it also requires less labor which reduces labor costs.
Furthermore, the number of joints is less when using AAC blocks as a single AAC block is almost equal to those 6 traditional red bricks. What this means is that the construction will be now faster and less mortar will now be required.
Eco-Friendliness
The final factor to consider AAC blocks over red bricks is the eco-friendliness that the AAC blocks offer.
The Red Bricks are not as eco-friendly as Autoclaved Aerated Concrete Blocks. They're made up of using topsoil, the removal of which causes soil erosion. You might be surprised to know that a single square foot of red brick walling consumes approximately 25kg of topsoil thereby negatively affecting the environment!
AAC blocks, on the other hand, have fly ash as one of their ingredients. Flyash is a waste by-product of the thermal power plant and is usually non-toxic in nature. And the manufacturing of AAC blocks also doesn't release any significant pollutants into the atmosphere.
Conclusion
Compared to traditional red bricks, the newer and innovative AAC blocks have many advantages to offer in all respects - Compressive Strength, Durability, Utility and Performance, Workability, and Sustainability.
One may argue taking the price is a negative factor for AAC blocks, as the cost of AAC is slightly higher than its counterpart, red bricks. But considering the long-term scenario, the positives of AAC outweigh its negatives, making it a perfect choice for construction projects.

The Top 9 Benefits of AAC Blocks for Construction
AAC blocks, or Autoclaved Aerated Concrete blocks, are a type of lightweight and durable building material made from a mixture of cement, lime, sand, water, and an expanding agent.
A mixture comprising the aforementioned ingredients is poured into molds and then allowed to cure in an autoclave, which creates a chemical reaction that causes the mixture to expand resulting in an aerated or porous and hard structure. Hence, the name Autoclaved Aerated Concrete.
The final product is strong, fire-resistant, and provides excellent insulation, with a host of other benefits as well, which make them a popular choice for construction projects. This article will explain in detail the 9 benefits AAC blocks offer when used in construction work.
9 Benefits of Using AAC Blocks in Construction Projects
1. High compressive strength
AAC blocks boast an average compressive strength of 3 to 5 N/mm2 compared to that of clay bricks which varies between 2.5 to 3.5 N/mm2. This makes AAC blocks significantly stronger and more durable than bricks of the same density making them a popular choice for high-rise construction projects.
2. Lightweight
AAC blocks are a lightweight alternative to traditional building materials. They weigh 3 to 4 times less than bricks and are 30% lighter than concrete, making them ideal for constructing taller buildings. This reduction in weight also helps to decrease the overall dead load of the building, making it more structurally sound.
3. Energy Efficient
AACs are known for their excellent thermal insulation properties. The tiny air pores within the blocks, combined with their thermal mass, make them highly effective at reducing heating and cooling escape within the buildings. So, both homeowners and businesses, love this!
4. Eco-Friendly
AAC blocks are a great choice for environmentally conscious builders and homeowners.
AAC blocks contain fly ash, which is an industrial waste, a by-product released from thermal power plants. Plus there are other non-toxic ingredients and their production process also emits fewer gases and consumes less energy compared to traditional red brick manufacturing.
5. High Workability
AAC blocks also offer higher workability. This implies that they can be easily cut, drilled, nailed, milled, and grooved to fit specific needs, making them a popular choice for construction projects that require precise measurements and unique shapes.
Furthermore, a single block of AAC is equivalent to six clay bricks, which means that there are fewer joints in the wall masonry. This not only reduces construction time by 20% but also reduces the amount of workforce required for a construction process.
6. Fire Resistant
AAC blocks are non-combustible in nature and can withstand high temperatures of up to 1600° C. In fact, they are fire-resistant for up to 6 hours of direct exposure, making them a popular choice for buildings prone to fires or high heat.
7. Acoustic Performance
As the AAC block is porous in nature, the sound absorption quality is superior. It offers sound attenuation of about 42 dB, blocking out all major sounds and disturbances which makes it ideal for schools, hospitals, hotels, offices, multi-family housing, and other structures that require acoustic insulation.
8. Seismic Resistant
The lightweight nature of AAC blocks makes them a popular choice for the construction of buildings in areas with high seismic activity. This reduces the overall mass of the structure thereby decreasing the impact of an earthquake on a building. Moreover, as AAC blocks are also fire resistant, this adds an extra layer of protection against accidental fires occurring due to earthquake damage.
9. Pest-resistant
AAC blocks are pet-resistant also as they are prepared from inorganic materials. This protects the structure made from them from pests such as termites, rodents, etc.
Conclusion
AAC blocks provide plenty of benefits during and after the construction of a building or any infra project. So, don't hesitate to opt for AAC blocks for your next construction work.
