Self Lubricating Bearing POM

Definition

The boundary lubricated bearing is a bearing that works by an extremely thin lubricating film between the bearing and the shaft. The film is formed by the adsorption of lubricant molecules, which can separate the metal surface. Under unsatisfactory working conditions, it can also reduce friction and wear to ensure the mechanical operation. It is used in many fields such as automobiles and machinery.

 

Product features

Self-lubricating property: Solid lubricants form a permanent lubricating film

Low friction: The dynamic and static friction coefficients are close, eliminating the "stick-slip" phenomenon

Chemical resistance: Resistant to erosion by oils and solvents

Dimensional stability: Low coefficient of thermal expansion, maintaining precise fit

 

Core advantage

Intelligent boundary lubrication: POM composite material + molybdenum disulfide filling, with a friction coefficient as low as 0.12-0.18

Super wear-resistant feature: Its wear resistance is three times higher than that of ordinary nylon, and its service life can reach 500,000 cycles

Shock absorption and noise reduction: The operating noise is below 35dB, making it perfectly suitable for precision equipment

Maintenance-free design: Built-in solid lubricant, no need for an external lubrication system
