SF-2
Marginal Pb-free Self-lubricating Bearing
Material Features
SF-2 Marginal Pb-free self-lubricating bearing is used steel-backing as its structure,sintered porous bronze as its interlayer,surface inlaid the modified POM.Suitable for marginally lubricated and dry operation onthe conditions of lubrication in dents grease.It has been widely applied to metallurgical machinery, Mine machinery,water conservancy machinery,vapor lovomotive,building machinery,agriculture machinery,steel rolling industry etc.

Application
1. Good load capacity and anti-wear.
2. It is used in high load capacities and low speed with rotational, oscillating or frequent stop-start motion.
3. It can work long time without oil in the condition of boundary lubrication, under oil or grease lubrication interval, the work is longer.
4. It is machinable for the thicker of POM.
5. The bushes can be applied in auto chassis, forging machine, metallurgical, civil engineering, power station, strip rolling industries etc.
