Bearing adapter sleeve

The main reasons for bearing seat life are as follows:

1. Load size and service life of bearing pedestal

The magnitude of the load on the bearing has a significant impact on the bearing life. When selecting a bearing, you can check the basic rated load of the selected bearing. Prevent bearing fatigue damage caused by practical loads exceeding the load accepted by the bearing. Otherwise, the bearing is not durable and the bearing is frequently replaced. Here is a tip: reduce the load of ball bearings by half, extend their service life by 8 times, and extend the service life of roller bearings by 10 times.

2. Bearing seat clearance and life

Due to the internal heat generated by the bearing and the heat released around the bearing, the temperature of the inner ring is higher than that of the outer ring during the operation of ordinary rolling bearings, resulting in a decrease in internal clearance. At this point, we should consider the clearance and bearing life. Due to the difficulty in knowing the temperature difference during operation, positive clearance is usually used for safety reasons.

3. Bearing seat tilt and life

The inclination here refers to the inclination of the shaft caused by the misalignment or unadjustment of the parallelism of both ends of the shaft during the installation process. The service life of the bearing decreases, and the greater the inclination, the shorter the service time. Except for self-aligning bearings, there are certainly no such problems.

4. Bearing seat data purity and service life

In addition to retirement conditions, the failure of bearing parts is mainly limited by the hardness, strength, toughness, wear resistance, corrosion resistance, and internal stress state of steel. The main internal factors that affect these properties and states are: ① martensite in hardened steel; ② Residual austenite in quenched steel; ③ Undissolved carbides in quenched steel; ④ Residual stress after quenching and tempering; ⑤ The impurity content of the steel. Under good smooth conditions, it is generally an internal starting point type of peeling. Therefore, the internal purity of data has a significant impact on its service life and cannot be controlled. All we can do is choose good bearings.
