Four-point Contact Ball Bearing

Schematic Diagram:

Parameters:

The contact angle of the Four-point Contact Ball Bearing is usually 35°. When carrying pure radial loads, each ball contacts with rings at four-point, and they are two-point contact under purely axial loads. The bearings can carry axial loads in two directions and specific moment loads. This type of bearings typically works at high speed when two-point contact is formed.
