Thrust ball bearings consist of two precision chrome stee or stainless steel washers (ring) and a ball complement spaced by bronze retainer(as well as stainless steel stainer). They can be supplied with or without radius ball grooves in the rings. Thrust bearings only support purely axial loads.
The material could be chrome steel or stainless steel at request,non-standard size can be designed for special application.
Thrust ball bearing:
It is mainly used for rolling bearings under axial load, its nominal contact angle is greater than 45 to 90. According to the
nominal contact angle is different and divided into: axial contact bearing - nominal contact angle of 90 of the thrust bearings:thrust angular contact bearing - nominal contact angle of 5 but less than 90 of thrust bearing.
Advantages:
1 small friction resistance, small power consumption, high mechanical efficiency, easy to start.
2, the size of the standard, with interchangeable, easy to install and disassemble, convenient maintenance.
3, compact structure, light weight, axial size is more narrow.
4, high precision, high speed, low wear, long service life.
5, it can simultaneously support both radial and thrust loads;
6, in a large load - speed range, the unique design can get excellent performance;
7, the bearing performance of the load, speed and speed of operation is relatively insensitive to fluctuations.
