Approach of extending the bearing’s lifetime:
one. The installation is correct, that affects precision, life, performance. And fill the bearing with lubricant after installation.
two. Don’t allow strong influence, such as hammer striking, transfer roller pressure 
3. Use the accurate installation tool, avoid to use cloth kind and short fibers
four. Lubricate the bearing to avoid rust with high quality mineral oil, especially in summer
5. CZPT inspection, such as the surrounding temperature, vibrate, noise inspection
six. Keep bearing cleansing from dirt, dust, pollutant, dampness.
7. CZPT need to not be ultra cooled.
