PRODUCT DESCRIPTION

Four-point-contact ball bearing is a separate type bearing, which also be said a set of angular contact ball bearing that can bear axial load in both directions,the inner and outer ring raceways are peach-shaped, when no load or pure radial load is applied, the steel ball and ring are in four-point contact.

 

As the contact angle increased, angular contact ball bearing has a higher axial load capacity, but a lower speed capability, thus, the ACBB with a smaller contact angle is better suited for high speed and high radial load applications.
