1, shaft and bearing room tolerance selection and control: bearing into the bearing should be flexible after the rotation without blocking sense. If there is a clear rotation is not flexible, then the size of the shaft is too large, the tolerance to be reduced. If the bearing presses into the shaft after hand rotation has a clear "rust" feeling, it may be too much tolerance of the shaft or shaft roundness is not good. So in the control of shaft and bearing room tolerance to control the roundness, the current domestic manufacturers only to control the tolerance, there is no control of the roundness.

2, the bearing assembly: because the bearing is a high-precision products, such as improper assembly is easy to cause damage to the bearing channel, resulting in bearing damage. Bearings in the assembly should have a dedicated mold, can not be tapping, in the press into the shaft when only a small circle of force, pressure circle can only large circle force. Assembly requires the use of air pressure or hydraulic pressure in the press up and down when the mold to be outside the horizontal state, if the tilt will lead to bearing damage due to force, leaving the bearing lead.
