Needle roller bearing

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. Common ball bearing designs include angular contact, axial, deep-groove, and preloaded pairs. The balls in ball bearings can also be configured in various ways. Ball bearings are used in a wide range of applications, some of which include skateboards and centrifugal pumps. Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races.

Angular contact ball bearings feature a contact angle that sustains significant axial loads in one direction at the same time as radial loads. Since an axial component is generated when radial load is applied, these bearings are typically used in pairs or multi-bearing sets. Shaft diameter: The diameter of the shaft will determine the necessary inner diameter of the bearing. Bearing outer diameter: Determine if the bearing’s outer diameter is suitable for the space where the bearing will be installed.
