We offer Support Bearing Ball Screw which are used for supporting the ball screws that are used at actuators of high precision and high speed machines, precision measurement equipment, robots, etc. It is a precision and high ability bearing. These are designed with polyamide cages and a greater number of balls then conventional angular contact ball bearings, so bearing stiffness is greater than conventional bearings. These bearings have a 60 contact angle so radial and thrust load combination can be sustained. This results in a simplified and compact shaft and housing design. These bearings are supplied with a pre-set preload so difficult adjustment and torque measurement is eliminated. Flush Ground set combination bearings are also available with suffix U. This permits the use of random combination where two or more bearings are mounted.
Main Features of Ball Screw Support Bearings:
1) High Axial Rigidity:
Greater number of balls with polyamide cage achieves significantly increased rigidity compared with conventional angular contact bearing.
2) Simple and Compact:
The 60 contact angles allows the bearing to simultaneously carry the thrust load and certain amount of radial load. This characteristic allows you to have a simple and compact design.
3) High Capacity and Low Noise:
The use of large balls results in higher bearing capacity beyond what adopted with the polyamide cage combined with the high performance, quiet operating, grease to achieve low noise.
4) Energy Saving:
Superior Designs offer low starting and running torque; minimizing power loss.
5) Easy Assembly:
Initial bearing preloading provides ease of assembly by eliminating complex assembly adjustment.
6) Universal Ground Set Combination(Flush Ground):
Universal ground set combination bearings are also available with a suffix U. This permits the use of random combination where two or more bearings are mounted.
