What Are The Materials Of Plastic Bearings?

Plastic bearings can adapt to some special working conditions. Because of its low density, self lubrication, corrosion resistance, wear resistance and low noise, NTN bearing plastic is often used to manufacture low load bearing ring materials in navigation, food, chemical industry and household office machinery. Stainless steel ball, plastic ball or glass ball can be installed in the bearing.

 

Commonly used plastics are:

1. Acetal bearing material:

This material fag bearing has low price, extremely low dynamic and static friction coefficient to steel, and high strength and stiffness. It is often used to manufacture the integral bearing seat with outer ring under light load;

2. Nylon bearing material:

It is a kind of cheap material with low friction. Due to the low number of ina bearings, it has strong self lubrication. Fillers such as graphite, molybdenum disulfide and polytetrafluoroethylene are often added to increase self lubrication, strength and stiffness. The working temperature can reach 120 ℃;

3. PTFE bearing material:

The friction coefficient is small, and when the load increases, the friction coefficient decreases accordingly. Glass fiber, graphite and bronze powder are often added to improve various performance indexes, and the working temperature is relatively high;

4. Phenolic bearing material:

It has high strength and high temperature resistance, but the friction NSK bearing factor is large and the wear is fast. After PTFE resin is used as filler, the friction factor can be reduced and the service life can be improved.
