Why your NSK angular contact ball bearings are often damaged, the root cause is here!

872 Published by admin1 Nov 01,2018

When NSK angular contact ball bearings are assembled, the clearance should not be too large or too small. If the clearance is too large, the number of rolling bodies that can bear the load at the same time is reduced, and the load of the single rolling element is increased, thereby reducing the rotation precision of the bearing and reducing the service life; if the clearance is too small, the frictional force is increased, and the generated heat is generated. Increase, increase wear and tear, can also reduce the service life of bearings, face such strict requirements, accurate installation, there are still many people's bearings often damaged, today to tell everyone about the root cause!

1. The NSK angular contact ball bearings are incorrectly installed or the installation method is incorrect. The use of brute force during installation will cause great damage to the angular contact ball bearing, which is one of the direct causes of damage to the angular contact ball bearing. Another installation The reason for the improper is because the angular contact ball bearing is not installed properly, and the installation has a large error. When installing the bearing, it should be evenly stressed and cannot be hammered directly. For example, if the interference is large, the bearing should be placed in an air-heating furnace or oil furnace with automatic temperature control, and the heating temperature should be strictly controlled below 100°.

2, angular contact ball bearings are not properly selected, angular contact ball bearings of the same angular contact ball bearing type is not exactly the same.
3. The internal contact of the NSK angular contact ball bearings receives dust and other pollution, resulting in poor rotation of the angular contact ball bearing. The storage room where the bearings are stored should be cleaned, and the drying should not be stored in the same warehouse as the chemical products. The relative humidity should not exceed 65%, and the bearings are not allowed to be stored on the ground.

4, angular contact ball bearings use poor lubrication, or improper use!
5. The bearing with nylon cage can work continuously for a long time at -40°-120°. It should not exceed 4 hours at 150° and the peak temperature can reach 180°.
