When a bearing hasn't been mounted on the shaft or bearing housing, fix its inner ring or outer ring, radial or axial movement is called the bearing clearance.
Bearing clearance in the operation(called work clearance) has a great influence on rolling fatigue life, temperature rise, noise and vibration and other performances.
We cann’t calculate the bearing clearance by hands, it only can be calculated by the tester machine.
If work clearance is very small, there will be a bad influence on the working life of the bearing.
1. Fatigue-life
2. Excessive friction lead to temperature increment.
3. Bearing with a high rotation speed needs a larger work clearance.
Method of extending the bearing’s lifetime:
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.
