1. Good bearing, good wear resistance.
2. For high-speed low-speed rotary motion, rocking movement and often open and close frequently under load and difficult to form a hydrodynamic lubrication of the occasion.
3. In the boundary lubrication conditions can be long-term refueling maintenance, and in the layer of oil to make bearings longer service life.
4. The surface of the plastic layer in the molding process can leave a certain margin, the assembly press into the seat hole after their own processing, in order to achieve better assembly size.
5. Products are mainly used in automotive chassis, metallurgical machinery, mining machinery, water machinery, construction machinery, agricultural machinery, rolling equipment.
