        Thrust roller bearings for axial load to bear the main shaft, the radial joint load, but the radial load must not exceed 55% of the axial load. Compared with other thrust roller bearings, this bearing friction coefficient is lower, higher speed, and with self-aligning performance.
        Thrust roller bearing chamber tolerance selection and control:
        Thrust roller bearings thrust thrust roller bearings should be rotated without a sense of flexibility. If the obvious rotation is not flexible, then the shaft size is too large, tolerances to be reduced. Such as thrust roller bearings pressed into the shaft rotation by hand there is a clear sense of "sand", it may be too large shaft tolerance or shaft roundness is not good. So in control of shaft and thrust roller bearing chamber tolerance must also control the roundness, at present, many domestic manufacturers only to tolerance control, there is no roundness control.
        Thrust roller bearing assembly:
        Because the thrust roller bearings are high-precision products, such as improper assembly is likely to cause damage to the thrust roller bearing channel, resulting in thrust roller bearing damage. Thrust roller bearings in the assembly should have a dedicated mold, not free to beat, press the shaft can only be a small circle by force, the pressure can only be a large circle of large circle stress. Assembly requires the use of pressure or hydraulic pressure in the upper and lower mold outside the horizontal state, if tilt will lead to thrust roller bearing channel damage due to stress, leaving the thrust roller bearing guide ring.
