Causes and Solutions for Bearing Lubrication Failure

Causes and Solutions for Bearing Lubrication Failure

According to statistics, approximately 36% of premature bearing failures are directly attributed to lubrication issues. Lubrication is not just about reducing friction; it also plays a vital role in heat dissipation, corrosion prevention, and contaminant exclusion.

Common Symptoms of Lubrication Failure
• Abnormal Noise: 
• Breakdown of the lubricant film leads to direct metal-to-metal contact, producing sharp screeching or humming sounds.
• Abnormal Temperature Rise: 
• Increased friction causes the temperature of the bearing housing to rise rapidly.
• Lubricant Deterioration: 
• Grease turning black, hardening, or experiencing oil separation.

Expert Solutions by GNSN Bearing

A. Precise Selection
• Select the appropriate lubricant based on the bearing's speed (dn value), load, and operating temperature.
B. Follow the "Five-Fixed" Principle
• Fixed Point:  Identify specific lubrication points.
• Fixed Quality:  Ensure consistent lubricant types.
• Fixed Quantity: Calculate grease volume (usually 1/3 to 1/2 of the internal space).
• Fixed Time: Establish scientific re-lubrication intervals.
• Fixed Personnel: Assign responsibility to specific personnel.
C. Environmental Control
• Upgrade sealing systems (such as using GNSN reinforced seals) to prevent external contaminants from entering.

Conclusion
Proper lubrication management can extend bearing life by 2 to 3 times. As your partner, GNSN Bearing provides not only superior products but also comprehensive technical support.

Technical Tip: 
When changing the type of bearing grease, it is essential to thoroughly clean out the old grease from the bearings first to prevent chemical reactions between greases of different base materials.
