Retainer assembly precision special mould can totally ensure bearing assembly accuracy.

On the fixed circle take minor offences surplus with condition is suitable surface, both sides are high precision and the roughness of the smaller shape, otherwise cause in installation and remove more difficult, in addition, also need to consider the influence of the main shaft hot elongation.

Pairs using double Angle contact ball bearing spindle, mostly load is lighter, with its over surplus quantity such as too large, the internal axial preloaded volume will significantly too large, cause adverse effect. Use double row short cylindrical roller bearing spindle and tapered roller bearing spindle, the load is opposite bigger, so its interference with the relatively large also.

Rotating contractor over surplus quantity of burning in possible range has also advised small. As long as really ensure the operating temperature influence of thermal expansion, and under the influence of the highest speed centrifugal force, not only because a tight fit motion of the surface or sliding. Fixed according to the work load size and collar bearing size, the selection of the tiny clearance fit or with interference, too loose or too tight, has not kept the original accurate shape.

Both precise rotations of the rings with surplus quantity, but also to the accurate calculation of the collar with appropriate amount fixed.

 
Axis and a hole and block the roundness shoulder vertical degree according to the corresponding precision requirements to bearing.
