Flush ground set combination bearings are also available with suffix U. This permits the use of random combinations where two or more bearings are mounted.
This type is used for for supporting the ball screws that are used as actuators of high precision and high machines, precision measurement equipment, robots, etc. This is a precision and high ability bearing.
These bearings are designed with polyamide cages and a greater number of balls than conventional angular contact ball bearings. For these reasons, bearing stiffness is greater than conventional bearings.
-Easy fitting and adjustment
These bearings are supplied with a pre-set preload so difficult adjustment and torque measurement is eliminated.
-Simplified bearing mounting structure
These bearings are supplied with a 60° contact angle so radial and thrust load combinations can be sustained. This result in a simplified and compact shaft and housing design.
