Angular Contact Ball Bearings 71900 Series AC/C/B/D Contact Angle
Angular contact ball bearings
Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.
The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis.
Key Feature
CSC can produce high quality Angular Contact Ball Bearings as the customer requests.We are happy to produce further construction methods. Please do not hesitate to contact us for special bearing characters
