Product pom composite bushings introduction
POM COMPOSITE BUSHING is a lead-free self-lubricating product with boundary made of carbon steel substrate, bronze powder, modified pom and other lubricant materials by special process, which has the characteristics of environmental protection. It not only has a certain chemical properties, at the same time, it has good physical properties and mechanical properties, can be used in all kinds of low speed load, sliding, rotation, swing, and instead of the traditional bearing linear reciprocating motion parts, because of wearing layer surface with oil holes facilitate assembly before daub grease, work with low coefficient of friction, breaking-in performance is good, wear resistance, etc.

Sliding layer POM (MoS2)/ lubrication pockets

Chemical properties: The surface polymer is resistant to chemical corrosion, so its corrosion resistance mainly depends on the steel back and the surface plating. Copper or tin plating on steel back surface can effectively prevent atmospheric corrosion; If working in corrosive medium, steel back can be galvanized, etc.

  • Flange bearings – Plain bearing within mountable housing unit
  • Sleeve bearings – Always self-lubricating & grease-free
  • Customized bearings – We will manufacture the exact self-lubricating bearing you need at a low cost.
  • Split type bushings – Easy to install
  • Simple design – Cost-effective

MATERIALS

  • Support material Steel backed bearings copper-plated or tin-plated
  • Intermediate layer Sintered bronze
  • Sliding layerPOM (MoS2)/lubrication pockets

Structure

1 Self-lubricating bearings Layer POM 0.3-0.5mm.
After rolling process completed, POM are filled in intersice of bronze layer, lubrication indents are stamped, which are full of oil grease, which will be removed and transferred on the mating surface, forms a physically lubricating film, which will reduced the firction coe. and protect the mating shaft.
2 Porous bronze layer;
The layer provides bonded strength of self-lubricating Layer.
3 Steel Backed bearings
The layer provides load & thermal conductivity
4 Copper / Tin layer bushings.

Composite Bushing Industry 

Bushing assembly, balancing sleeve, brake clamp, steering kingpin axle sleeve and truck tail plate axle sleeve, haulage truck, crane, truck crane, forest machinery, packaging machinery, construction machinery, hydraulic motor, agricultural machinery, mining machinery, metallurgical machinery, hydraulic machinery, steam truck, steel rolling industry, etc.

The composite bushings are made from a steel backed bushing, in which MoS2 is sintered on the surface, using an intermediate layer of bronze powder as a binding agent. These raw material slabs are then cut into a rectangular shape, then wrapped and calibrated to the right size.

Composite Bushing Application

Wrapped sliding bearing, wrapped bushing, steel backed POM (MoS2)/lubrication pockets, DIN 1494/ISO 3547, Low-maintenance used in cranes, truck cranes, tail gates, port equipment and agricultural machinery and construction machines.

composite pom bushing is a Low-maintenance bearing material with MoS2 sliding layer and lubrication pockets. An initial greasing during installation is necessary, after that, periodic greasing with oil or grease is mandatory.
