Common Causes of Powder Metallurgy Bearing Damage

Common Causes of Powder Metallurgy Bearing Damage

What are the common causes of powder metallurgy bearing damage? Powder metallurgy bearings are important basic components of various mechanical equipment. The precision, performance, life and reliability of powder metallurgy bearings play a decisive role in the precision, performance, life and reliability of the host. However, powder metallurgy bearings may be damaged during use. What are the common causes of powder metallurgy bearing damage? Zhangnwei Precision Powder Metallurgy Factory tells you:

There are many reasons for the damage of powder metallurgy bearings, such as overload, low sealing efficiency, too tight fitting, resulting in too small bearing clearance, etc. These factors have special damage types, which will leave special damage traces.

Powder metallurgy bearing

The influence of temperature on the bearing is usually indicated by high temperature. High temperatures are also harmful to bearing lubricants. Sometimes bearing overheating can be attributed to the lubricant of the bearing. If the powder metallurgy bearing is transferred above 125 ℃ for a long time, the bearing life will be reduced. The factors that cause high temperature bearings include insufficient or excessive lubrication, excessive impurities in lubricating oil, excessive bearing wear, insufficient clearance, and high friction caused by oil seals.

Therefore, whether measuring the bearing itself or other important parts, it is necessary to constantly monitor the temperature of powder metallurgy bearings. If the operating conditions remain unchanged, any temperature change may indicate a fault. Generally speaking, 1/3 of powder metallurgy bearings are fatigue damaged, 1/3 are poorly lubricated, and the other 1/3 are due to pollutants entering the bearings or improper installation and treatment.

This is the common cause of powder metallurgy bearing damage introduced by Zhongwei Precision Powder Metallurgy Factory. Zhongwei reminds us that only by understanding the causes of bearing damage can we pay more attention to and reduce the damage probability of powder metallurgy bearings in the future.
