When to Use a ZZ Bearing

ZZ bearings are commonly recommended for:

• High-speed equipment
• Dry environments
• Continuous industrial systems
• Applications requiring lower rolling resistance
• Machinery with limited moisture exposure

2RS bearings are generally selected when stronger sealing protection is required against water and debris.

Usage Recommendations

To improve bearing service life:

• Check shaft alignment
• Monitor operating temperature
• Avoid excessive impacts
• Control abnormal vibration
• Use proper installation methods
