We can make all sizes and types of this bushes, also by clients requests!
The specification of this 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
