Bearing Bush, Sintered Bronze Bushing
This bushes is a kind of high strength cast bronze based material and on the surface of ehich is embedded with preformed solid lubricant...The bushings has both the virtues of the copper alloy and the solid lubricant, can be applied under dry, high temperature, high pressure, corrosive, water or other chemical environment, where no oil can be introduced. The bushings is now used in successive casting machinery, steel rollers in metallography, mineral machinery, ships, turbogenerators, hydraulic turbines and injuection molding machinery for plastics. We can make all sizes and types of this bushes, also according to the clients requests!
The specification of the bushes as follows:
Material: High-strength and Graphite;
Load Capacity: 150N/mm2;
Temperature Limit: -100~+300;
Max. Sliding Velocit: 1.5M/s;
Friction Clef: 0.05~0.25;
PV Limit(dry): 3.3N/mm2*m/s;
PV Limit(oil): 16N/mm2*m/s.
Features:
- Exhibits incomparable performance under high load, low speed operation. Usable without lubrication.
- Excellent wear resistance in such places where an oil film is difficult to be formed due to reciprocating, oscillating motions and frequently intermittent operations.
- Remarkable resistance to corrosion and resistance to chemical attack.
- Available in various dimensions as standard or customized product
we can supply self-lubeicating bearing&bushing
