Airsoft BB is widely used in bearings. POM and PAairsoft BB have good mechanical strength and wear resistance. They are suitable for making relatively precise plastic bearings. The airsoft BB has a specific gravity of 1.41-1.43 g/cm3 and an operating temperature of -60 to 120. Degree, the surface strength is high and smooth, basically no tension occurs, its good self-lubricating performance and low friction coefficient, on the basis of maintaining the traditional advantages of plastic bearings, can be applied to precision and high speed operation. Among them, POMairsoft BB is widely used in plastic bearings. Generally, the inner and outer airsoft BB materials are made of POM and PA materials. The balls are glass balls, stainless steel balls or ceramic balls. Such plastic bearings perform well under alkaline conditions but are not suitable. Operates in an acidic corrosive environment.

The application characteristics of airsoft BB in bearings are as follows.

1. Airsoft BB has high rigidity and high hardness, and its impact strength is high even at low temperatures.

2. Excellent flexibility, good creep resistance.

3. High heat stability and very good dimensional stability.

4. Good sliding performance, wear resistance.

5. Environmental protection, suitable for contact with food, suitable for making plastic bearings, deep groove ball bearings, self-aligning ball bearings, cylindrical roller bearings, needle bearings, tapered roller bearings, thrust ball bearings, outer spherical bearings, universal joints Bearing, one-way bearing.
