customized Short bearing roller

Category:

Short small cylindrical rollers

Keywords:

Short bearing rollers are one of the rolling bearings and are one of the widely used parts in modern machinery. It relies on the rolling contact between the main components to support the rotating parts. Roller bearings are now mostly standardized. Roller bearings have the advantages of small starting torque, high rotation accuracy, and convenient selection.

Short bearing rollers are one of the rolling bearings and are one of the widely used parts in modern machinery. It relies on the rolling contact between the main components to support the rotating parts. Roller bearings are now mostly standardized. Roller bearings have the advantages of small starting torque, high rotation accuracy, and convenient selection.

When selecting bearings, the main considerations are as follows:

Bearing load
The size, direction and nature of the load on the bearing are the main factors for selecting the bearing.
When selecting the bearing according to the size of the load, compared to the point contact of the ball bearing, the main elements in the roller bearing are in line contact, which is easy to bear the load, and the deformation after the load is also small.

When selecting bearings according to the load direction, for pure axial loads, thrust bearings are generally selected. For larger axial forces, choose thrust roller bearings. For smaller axial forces, choose thrust ball bearings. For pure radial loads, deep groove ball bearings, cylindrical roller bearings or needle bearings are generally used. When bearing a radial load while still bearing a small axial load, deep groove ball bearings or tapered roller bearings can be selected; when the axial load is large, an angular contact ball with a larger contact angle can be selected Bearings or tapered roller bearings.
