Description
DU bush
The DU bearing is designed in combination with the working principle of the oil cylinder and shock absorber. It is more wear-resistant in the absence of oil, and is especially suitable for occasions with large lateral forces and frequent reciprocating motion.

Maximum allowable PV value (oil): 50N/mm2.m/s
DU bush application
1. The mixture of PTFE and lipophilic fiber can form a good transfer film, thereby protecting the grinding shaft during the movement.
2. Good wear resistance and low friction coefficient.
3. Good running performance, no shaft bite.
4. Can be used for rotation, swing, reciprocating motion.
5. Because it does not contain lead, it can be used in food machinery, medical machinery and other green environmental protection equipment.
6. Also especially suitable for occasions with frequent reciprocating motion and large lateral force. Suitable for cars,Motorcycle shock absorbers and various types of hydraulic cylinders.
