POM Sliding Bearings SF-2 Series ( SF-2 , SF-2Y ) , DX Self Lubricating Bushing

It is made of high quality low-carbon steel, sintered porous bronze as its interlayer, with the compound of POM& PB as its surface. And has good load capacity & wear-resistant. It's used in vehicle chassis, forming machine tools, steel metallurgical machinery, mineral mountain machinery, hydraulic industry and rolling steel industry, etc.

Physical and Mechanical Performance

Normally, the surface polymer is chemical-erosion resistant quality. So its erosion-prevention quality is primarily decided by the quality of the steel back and its plating layer. Air-erosion could be effectively prevented if the steel back is bronze or tin-plated. If the bush is to be used in erosive environment, the steel back needs to be plated with zinc, nickel or nickel-chrome ally, etc.

DX bush Application Feature

1. Good carrying capacity, good wear resistance.

2. Applied for high load low speed rotation and rocking motion, often used in frequent opening and closing under load and hard to form hydrodynamic lubrication occasions.

3. Don’t have to refuel and maintenance under the long-term boundary lubrication conditions, and refueling in the bearing layer made a longer service life.

4. A certain margin kept on the surface of the plastic layer during molding, self-processes after assembly was pushed into holes to achieve a better assembly size.

5. Mainly used in auto chassis, metallurgical machinery, mining machinery, irrigation machinery, construction machinery, agricultural machinery and steel rolling equipment.

6. Widely used in lead-free fields for no lead containing.
