What are plastic coated bearings?
2021-02-26
Plastic-coated bearings generally refer to a layer of plastic on the outer bread of the bearing. The plastic materials are generally nylon PA, polyoxymethylene POM and engineering plastics polypropylene and pp. Outsourcing plastic has certain hardness, impact resistance, friction resistance and certain self-lubricating type.
POM plastic-coated bearings POM material has good mechanical strength and wear resistance, and is suitable for making more precise POM plastic-coated bearings. With its good self-lubricating performance and low friction coefficient, it can be applied to precision and high-speed motion on the basis of maintaining the traditional advantages of POM coated bearings. Among them, POM plastic bearings are the most widely used of all coated bearings. It is widely used in machinery and equipment, industrial assembly lines, furniture and hardware accessories. According to different application purposes, the outer shape of the coated bearing can be made into different shapes, and it can be made into a pulley such as a V-shaped groove. V-groove, etc.
POM coated bearing characteristics
1. High rigidity, high hardness, high impact strength even at low temperature;
2, excellent elasticity, good creep resistance
3, high heat resistance stability and very good dimensional stability;
4, good sliding performance, wear resistance;
5. Physiologically inert, suitable for contact with food.
6, high heat resistance stability and very good dimensional stability;
