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
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.
