The Purpose Of Bearing Preloadt

SKF W 6200 bearing

The main purpose of preload and representative examples are as follows:

⑴Improve the guiding accuracy of the bearing. Spindle bearings and measuring instrument bearings of machine tools.

⑵ Improve rigidity. Bearings for main shaft bearings of machine tools and pinion gears of automobile differential mechanisms.

⑶ Reduce vibration and noise during operation. Bearings for small motors.

⑷ Prevent the rolling element from sliding relative to the inner and outer raceways caused by the moment of inertia. High-speed rotating angular contact ball bearings, thrust ball bearings.

⑸ Compensate for wear and pressure during operation, and extend working life.

⑹Keep the rolling element and bearing ring in the correct position. Thrust ball bearings and thrust spherical roller bearings mounted on the horizontal shaft.
