What is the purpose of a roller bearing?

Roller bearings are a type of rolling bearings and are one of the widely used components in modern machinery. It relies on the rolling contact between the main components to support the rotating parts. Most roller bearings have now been standardized. Roller bearings have the advantages of small starting torque required, high rotational accuracy and convenient selection.

Roller bearings support rotating parts by the rolling contact between their main components. Different roller bearings can withstand different radial and axial forces. When choosing roller bearings, the selection should be made based on specific working conditions.

Roller bearings mainly include self-aligning roller bearings, thrust self-aligning roller bearings, tapered roller bearings and cylindrical roller bearings, etc.
