Exploring the route to greater efficiency

Featuring a redesigned brass cage that delivers reduced noise and vibration levels and improved robustness, the new 40 degree contact angle bearings increase the limiting speed up to 30% compared to the previous design.

The new cage geometry and the use of stronger brass material reduce cage contact forces and increases cage strength, ensuring greater tolerance of shock loads and vibration, while delivering the higher speed capability, even under severe operating conditions.

In addition to the redesigned 40 degree contact angle, a new contact angle of 25 degrees is also offered, giving the bearing a further 20% increase in speed over that of the 40 degree version, while enabling higher radial loads to be accommodated. In each case, the ball-to-cage contact arrangement allows cooler running and greater temperature stability, while noise and vibration levels are reduced by 15% in both the 40 and 25 degree versions. Sealed variants of these bearings are also available for applications that may be more difficult to maintain, preventing contaminants from entering the bearing during installation and subsequent operation.

Bearing arrangements that include a 40 degree contact angle unit taking the main load with a 25 degree unit acting as a back-up bearing offers improved robustness for applications where the axial load is predominantly in one direction, resulting in longer service life.
