How can we ensure that the bearing is not deformed during installation? Below we provide some attention, hope useful for you:

Axis and the roundness of the bore, vertical shoulder block must be in accordance with the corresponding pre cision of the bearing requirements. angular contact ball bearing

It is necessary to accurately calculate the rotating ring with the amount of interference, but also very accurate calculation of the appropriate co-ordination of the fixed ring.
And the maximum speed the centrifugal force of the impact of rotating rings burning the amount of interference should be made smaller to the extent possible. Ensure the operating temperature of the thermal expansion affect. So as not to cause a tight fit to the surface of the creeping or sliding. Fixed ferrule according to load size and bearing size, select a very small clearance fit or interference fit is too loose or too tight are not conducive to maintaining the original precise shape.

3 and higher operating temperature, the bearing operation in the high-speed conditions. Special attention sho uld be rotating ring with not too loose to prevent the emergence of the eccentric, and a fixed ring with the non-emergence of the gap to prevent the ring deformation under load and excitation vibration. cross roller bearing

4 otherwise cause installation difficulties demolition more difficult to take a small interference with the condition is to match the appearance of the two sides have high shape accuracy and smaller roughness on the fixed circle. In addition, you also need to consider the impact of the spindle thermal elongation.

5 most of the load lighter, uses a pair of double angular contact ball bearing spindle. Cooperated with the amount of interference, such as large internal axial preload amount will be significantly larger, resulting in beneficial effects. Spindle double row cylindrical roller bearings and tapered roller bearing spindle, the load is relative ly large, so with the earnings are also relatively large. contact ball bearing
