Contact angle α⁰

The contact angle is formed by a straight line drawn between the points of contact of the balls with the raceways and a plane perpendicular to the bearing axis. Externally applied loads are transmitted from one ring to the other along this line.

• The contact angle is designed into the bearing and changes during operation with the speed, the external forces and the difference in temperature between the inner and the outer ring.

With increasing contact angle

• Limiting speed decreases
• Radial rigidity decreases
• Axial rigidity increases

RHD bearings with 15° and 25° contact angles. Other contact angles available on request.
