Common plastic bearing materials and advantages & disadvantages

It is well known that plastic bearings currently can be generally classified into plastic rolling bearings and plastic sliding bearings. The plastic sliding bearing generally has a self-lubricating function on the working surface; the plastic sliding bearing is generally made of engineering plastic with better performance.
 
Common plastic bearing materials and advantages & disadvantages:
 
POM and PA are commonly used in plastic bearing materials, working temperature from -60 ° C to 100 ° C, surface strength is high and smooth, basically no tension, its good self-lubricating properties and low friction coefficient in the maintenance of plastic bearing. Based on traditional advantages, it can be applied to precision and high speed operation. Among them, POM plastic bearing is widely used in all plastic bearings. Generally, the inner and outer spherical materials are POM or PA, and the cage is made of glass fiber reinforced nylon 66 (GRPA66-25). The balls are glass balls, stainless steel balls or ceramic balls. These bearings perform well under alkaline conditions, but are not suitable for operation in acidic corrosive environments.
