What are the reasons why bearings are not durable?

The main function of bearings is to support mechanical rotating bodies, reduce their friction coefficient during motion, and ensure their rotational accuracy.

It can be said that bearings, as important components in modern mechanical equipment, may face situations where they need to be replaced due to wear or other reasons under different working conditions.

After all, bearings have a service life.

But the service life of bearings is much shorter than the normal service cycle, and replacement is very frequent, which is abnormal.

Based on our over 30 years of lubrication experience, the service life of bearings is generally too short for two reasons:

(1) Unqualified bearing quality, such as poor bearing tolerance; Internal compression will exacerbate bearing wear,

This greatly shortens the service life of the bearings, which requires the replacement of high-quality bearings.

(2) Poor bearing lubrication, the selected bearing grease must meet the operating conditions of the bearing, such as suitable temperature resistance range, good lubrication performance, and whether extreme pressure resistance is required. Only by selecting according to the bearing operating conditions can bearing failure be reduced and bearing servic
