Application characteristics
DU composite bushing/rolled collar, is based on steel substrate, the middle bronze powder, sintered spherical surface rolling a mixture of polytetrafluoroethylene (PTFE) and lead (pb), rolling and sliding bearing, the general surface tin exports (silver).It has a small friction coefficient, good wear resistance, corrosion resistance, the characteristics of the oil free.Using the product can reduce costs, reduce the size of our machinery, avoiding the phenomenon of bit axis and the noise of the machinery, etc.
Range of application
The factory production of composite bearing, composite liner has been widely used in various mechanical sliding parts, such as printing machine, elevator, textile machines, tobacco machines, machines, hydraulic truck, micro-motor, electromagnetic valve, automobile, motorcycle and the agriculture and forestry machinery and so on.
