Environmental protection leads free bushing series, color is orange, orange, blue POM composite.

Non-lead boundary lubrication bearing is improved on the basis of pom bushing. It can be applied to the field where non-lead is required. Now it’s widely used in textile machines, auto operating parts, and other middle speed, middle load, and grease lubrication occasions.

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

VIIPLUS.COM is one of the entities specialized in the production of self-embellishment bearings, sliding bearings, composite bearings, oil-free bearings, dry bearings and maintenance-free bearings in China. Its product quality and performance have reached the level of foreign counterparts.

Pre-lubricated bearing. Be sure to fill with lubricant when installing.

[Features]· Quiet operation free of squeaking or knocking.
· Low friction characteristics prevents damage to the shaft (mating surface).
· The bearing surface remains virtually wear-free with minimum amount of lubricant (grease or oil).
· The frictional force at startup is extremely low.
· This enables smooth rotation at startup and at low speed under high load conditions.
· Superior non-seizure properties.
· Shaft misalignment tolerance is excellent.
· Can withstand impact loads.
· Excellent load-carrying performance even under oscillating and fretting conditions

Composite Bushing Industry

POM bearings

Our range of wrapped acetal-lined bearings is suitable for rotary and oscillating movement applications. They benefit from long re-lubrication intervals, no absorption of water, outstanding damping behaviors, and have a low susceptibility to edge loading.

The POM bushing range is ideal for the automotive, machine building, and agricultural industries and indeed any application where lubricant cannot be supplied continuously.

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.

Why are we the best?

We have a range of sliding cylindrical bearings made from a composite structure material. The support consists of carbon steel backed on which a porous layer of bronze is sintered then impregnated with a co-acetal plastic. The polymer surface has indentations in which the lubricating grease is located and protects the contact surface. The main products in the bushings range are cylindrical rings (DIN 1494), as well as special parts made to customer specifications.

Before purchasing a plain bearings, be sure to ask these questions:

  • Bushings Type
  • Bushings Size: Plain Bearing – ID, OD, Length mm or Flange Size
  • Bushings Wall Thickness
