Maintenance and Usage Best Practices

Proper maintenance is crucial to ensure optimal performance and longevity of Rexnord bearings:

• Lubrication: Use the recommended lubricant for the specific bearing type and application. Regular lubrication reduces friction and extends bearing life.
• Mounting: Follow the manufacturer's guidelines for proper mounting procedures to prevent damage and ensure proper alignment.
• Inspection: Regularly inspect bearings for signs of wear, damage, or contamination. Early detection can prevent failures and extend bearing life.
• Storage: Store bearings in a clean, dry environment to prevent corrosion and contamination. Use proper handling techniques to avoid damage.

Tips and Tricks

• Choose the right bearing type for the specific application, considering factors such as load, speed, and operating environment.
• Use high-quality lubricants and follow the manufacturer's recommendations for lubrication intervals.
• Implement a regular maintenance schedule to detect and address potential problems early.
• Consider using specialized bearings for extreme environments or demanding applications.
• Seek professional advice from Rexnord engineers or authorized distributors for complex applications or technical support.

Common Mistakes to Avoid

• Overloading: Operating bearings beyond their rated load capacity can lead to premature failure.
• Improper mounting: Incorrect mounting procedures can compromise bearing performance and cause damage.
• Lack of lubrication: Insufficient or improper lubrication is a major cause of bearing failures.
• Ignoring inspection: Neglecting regular bearing inspections can result in undetected damage and lead to catastrophic failures.
• Using contaminated lubricants: Contamination of lubricants can increase friction and accelerate bearing wear.

Step-by-Step Approach

Follow these steps for effective bearing maintenance:

1. Inspection: Visually inspect the bearing for any visible damage or wear.
2. Cleaning: If necessary, clean the bearing with a clean cloth and solvent.
3. Lubrication: Apply the recommended lubricant to the bearing surfaces.
4. Reassembly: Reassemble the bearing and tighten the bolts to the specified torque.
5. Testing: Run the bearing at low speed to check for any abnormal noise or vibration.
