Maximize performance and lifespan of your precision angular contact ball bearings with these essential tips:

1. Proper Installation – Prevent Early Damage

✅ Fit Perfectly
Bearings should rotate freely after installation. If tight, check if the shaft is oversized or out of round. Correct both size and geometry before proceeding.

✅ Use Proper Tools
Always install using presses, sleeves, or mandrels. Never strike directly with a hammer. Apply pressure only to the ring that fits tightly (inner ring for shaft mounting, outer ring for housing).

✅ Keep It Clean
Install in a dust-free environment to prevent contamination from dirt or debris.

2. Smart Operation – Maximize Daily Performance

✅ Protect Against Contamination
Ensure effective sealing against dust and moisture. Avoid excess grease or oil near bearings.

✅ Avoid “Paint Rust” (in Motors)
Use high-quality motor paint and allow it to fully cure and off-gas before installing bearings inside the motor.

✅ Lubricate Correctly

• Use lubricants designed for your bearing’s operating temperature.
• Follow manufacturer recommendations — too much or too little grease/oil can cause failure.
• Regularly inspect lubricant condition; old or burnt grease must be replaced.

✅ Balance Rotors
Unbalanced rotating components generate vibration, which accelerates bearing wear. Balance new rotors and inspect regularly if unusual vibration occurs.

✅ Monitor Conditions
Stop operation immediately if you notice any of the following:

• Unusual heat
• Strange noises (e.g., grinding, squealing)
• Excessive vibration

3. Maintenance & Storage – Extend Service Life

✅ Regular Inspections (Every 3–6 Months)

• Check for signs of wear, rust, or cracks.
• Listen to the bearing while running — abnormal sounds may signal issues.
• Monitor vibration and temperature levels.

✅ Clean Carefully (If Necessary)

• First, gently remove heavy deposits without spinning the bearing forcefully.
• For fine cleaning, use filtered solvent (such as clean kerosene or mineral spirits), rotating slowly. Always use fresh, uncontaminated solvent.

✅ Dry & Re-Lubricate Immediately After Cleaning
Never store or reuse a bearing without drying and reapplying proper lubrication.

✅ Store Spare Bearings Properly

• Keep in original sealed packaging.
• Store at room temperature (~20°C / 68°F).
• Maintain humidity below 65%.
• Keep bearings off the floor and away from dust, moisture, and corrosive chemicals.

✅ The Result:

By following these best practices, you’ll reduce downtime, avoid costly failures, and get the most value from your angular contact ball bearings.
