How to expand the lifetime of angular contact ball bearing

1. The installation is correct, that affects precision, life, performance. And fill the bearing with lubricant after installation.

2. Don't allow strong impact, such as hammer striking, transfer roller pressure

3. Use the accurate installation tool, avoid to use cloth kind and short fibers

4. Lubricate the bearing to avoid rust with high quality mineral oil, especially in summer

5. General inspection, such as the surrounding temperature, vibrate, noise inspection

6. Keep bearing cleaning from dirt, dust, pollutant, moisture.

7. Bearing should not be ultra cooled.

Description:

Angular contact ball bearings are designed for combination radial and axial loading. Single-row bearings

have high thrust capacity in one direction. Some single-row bearings are specifically designed for duplex

mounting in sets for maximum performance. Double-row Conrad bearings can accommodate thrust in

both directions.
