What are the types of rolling bearings?
Types of rolling bearings
- Axial bearings.
- Angular contact bearings.
- Deep groove ball bearing.
- Self-aligning ball bearings.
- High speed angular contact ball bearings.
What are the types of bearings?
There are many different types of bearings, each used for specific purposes and designed to carry specific types of loads, radial or thrust. Here, we’ll look at the 6 most popular types: plain bearings, rolling element bearings, jewel bearings, fluid bearings, magnetic bearings, and flexure bearings.
How many types of rolling contact bearings are there?
There are two types of self-aligning rolling contact bearings, self-aligning ball bearing and spherical roller bearing. The self-aligning ball bearing consists of two rows of balls, which roll on a common spherical surface in the outer race.

Rolling-element Bearings
- Deep-Groove Ball Bearings.
- Angular Contact Ball Bearings.
- Self-Aligning Ball Bearings.
- Thrust Ball Bearings.
What is the roller bearing?
A roller bearing is a type of rolling-element bearing that uses a cylinder (roller) instead of a ball. In general, the cylindrical bearings allow for greater radial loads. They are made to handle heavier loads than ball bearings.
How many types of bearings are there PDF?
Flexure Bearings However, flexures require no lubrication and exhibit very low or no friction. Another criterion for categorizing bearings is the direction of the load they can accommodate. From this point of view, bearings are grouped into three main categories: radial bearings, thrust bearings, and linear bearings.
Where are roller bearings used?
Some of the widely used applications of roller bearings are aviation cargo systems, engines, agriculture industry, heavy equipments and machinery, solar panels, medical equipments, automobile industry, power houses and many others.

What is a bearing PDF?
A bearing is a machine element which supports another moving machine element (known as journal). It permits a relative motion between the contact surfaces of the members, while carrying the load.
What are roller bearings made of?
chrome SAE 52100 bearing steel
Roller, ball and tapered roller bearings are usually made of chrome SAE 52100 bearing steel. This material has excellent wear resistant capacity and a Rockwell hardness of about 64 HRC.
What is roller bearings used for?
Roller bearings are used in all main shaft and auxiliary drive shaft applications to support pure radial load, and allow for axial shaft elongation due to temperature changes with no additional load effect on the bearing.
What are application of rollers?
Aside from constructions, rollers in general, are also used in agriculture. They’re a supplementary machine that’s used to flatten land or break up large chunks of soil. Most of the time, they’re used after plowing or disc harrowing is done.
How do roller bearings work?
Roller bearings — also known as rolling-element bearings — are similar to ball bearings in that they are designed to carry a load while minimizing friction. However, roller bearings transmit loads using cylinder rolling elements, rather than balls, to maintain the separation between moving parts of the bearing.
What is bearing hardness?
The typical surface hardness for bearing components made from this material ranges from 60- 64 on the Rockwell hardness C scale (Rc).
What is roller bearing made of?
Roller, ball and tapered roller bearings are usually made of chrome SAE 52100 bearing steel. This material has excellent wear resistant capacity and a Rockwell hardness of about 64 HRC. Bearings made of chrome steel can function at temperatures up to 120°C, and upon heat treatment, they can even go as high as 220°C.

Which metal is used for bearings?
Most ball bearings are made of a type of steel known as high carbon chromium steel, often called chrome steel. This is used for reasons of cost and durability. Bearings are also made from other materials such as stainless steel, ceramics and plastic.

What are the advantages of roller bearing?
Advantages of Rolling Contact Bearings
- Low starting and running friction except at very high speeds.
- Ability to withstand momentary shock loads.
- Accuracy of shaft alignment.
- Low cost of maintenance, as no lubrication is required while in service.
- Small overall dimensions.
- Reliability of service.
- Easy to mount and erect.
