Product Description

POM Composite Bearings | Self-lubricating Bronze Bushings

The POM composite bearing trademark denotes a range of sliding bearings produced from a material with a composite structure. The backing consists of carbon steel onto which a porous layer of bronze is sintered and then impregnated with a co-acetal plastic. The polymeric surface has indentations in which the lubricating grease lies and protects the mating surface. The main pom composite bearings in the pom composite bearing range are the cylindrical bushings (DIN 1494), but thrust washers and strips are also available as well as special parts made to customer specifications.


The POM composite bearing is suitable for rotating and oscillating movement, less maintenance requirements due to the long re-lubrication intervals, lower wear, lower susceptibility to edge loading, no absorption of water and therefore no swelling, good damping behaviours, good resistance to shock loads.

POM Composite Bearing Material


1. POM (Acetal) 0.30-0.50mm:has high wear resistance and low friction. The pom composite bearing surface has a pattern of circular indents, which should be filled with grease on assembly.
2. Sintered bronze powder 0.20-0.35mm: provides maximum thermal conductivity away from the pom composite bearing surface, also serves as a reservoir for the resin mixture.
3. Low-Carbon Steel: provides exceptionally high load carrying capacity.
4. Copper/Tin plating 0.002mm: provides good corrosion resistance.
 

POM Composite Bearing Typical Application

 
Recommended for applications involving intermittent operation or boundary lubrication.
  • Automotive: suspension joints, kingpin assemblies, automobile driving joint hinges, steering and other linkages, articulation joints, and rear chassis hinges.
  • Machine Tools: spindles in drill, grinding, and milling machines, and ram guide plates in multi ram presses.
  • Agricultural Equipment: gearboxes, clutch assemblies, bale trips and wheel caster swivels for bale accumulators, front axle pivot bearings, steering idler box bearings and kingpin bearings for harvesters.

 

In the food, medicine and other mechanical industries, the use of environmentally-friendly oil-free lubrication bearings not only reduces the impact of lubricating oil on the working environment during maintenance, but also prevents the pollution of heavy metals to pom composite bearings products.

 

Boundary lubricated lead-free bearing, this pom composite bearings and VSB-2 have the same structure and performance, at the same time has the environmental protection function, under the boundary lubrication condition can be used for a long time without oiling, wear resistant layer surface has oil storage pit. POM composite bearings Products are widely used in gold processing machinery, mining machinery, water conservancy machinery, automobile, construction machinery, agricultural machinery, steel rolling industry, food machinery, pharmaceutical machinery, tobacco machinery, etc.

 

 

We choose low carbon steel as the base of the bearing
