Antifriction bearings are also known as rolling element bearings.
Antifriction bearings use rolling elements, such as balls or rollers, to reduce friction between moving parts.
This type of bearing allows for smoother and more efficient movement compared to sliding bearings, which rely on a thin layer of lubricant to reduce friction.
Examples of antifriction bearings:
- Ball bearings: These bearings use small, hard balls to reduce friction.
- Roller bearings: These bearings use cylindrical rollers to distribute the load more evenly and handle heavier loads.
- Needle bearings: These bearings use small, long rollers to reduce friction and increase load capacity.
Why are they called antifriction bearings?
They are called antifriction bearings because they minimize friction between moving parts, which reduces wear and tear and improves efficiency. This is achieved by using rolling elements instead of sliding surfaces, which significantly lowers the coefficient of friction.
