Composite dry sliding thrust washers provide a cost-effective and space-saving solution for axial location. Both PTFE and POM composite thrust washers are suitable where oscillating and rotational movement can occur. These washers are punched from the composite material and have as standard a hole to take a pin or screw to prevent the washers from rotating on their seat.

After the rolling process is completed, POM mixtures are filled in the interstice of the bronze layer. Under normal operation, Part of the POM mixture on the top layer will be removed and transferred to the mating surface, forming a physically lubricating film, which will reduce the friction cone. and protect the mating shaft.

Description
POM composite thrust washers consist of a sheet steel backing on which a 0,2 to 0,4 mm thick layer of tin/bronze is sintered. The principal characteristic of these washers is their relatively thick (0,3 mm) covering layer of acetal resin (POM – polyoxymethylene) with additives. This covering layer has pockets to retain grease and is firmly attached to the sintered tin/bronze layer. POM composite dry sliding thrust washers are designed for applications where axial space is limited, maintenance is not possible, and where lubricant starvation can occur.
As well as for composite bushings and strips, we manufacture composite thrust washers as standard from PTFE and POM composite materials.
POM composite thrust washers
POM composite thrust washers have pockets in the sliding surface, which serve as grease reservoirs and should be filled with grease prior to installation. This makes these washers suitable for applications that require minimal maintenance under difficult operating conditions, for example in contaminated environments where lubricant cannot be supplied continuously or frequently. Despite of their compact design, POM composite washers can accommodate heavy axial loads and are less sensitive to misalignment. They are suitable for slow rotational or oscillating movements.
The thickness of the covering layer makes these washers less sensitive to misalignment and the edge loading associated with that misalignment.

Carbon Steel + Copper Powder + (POM + Pb + Filler)
Steel backed with copper-plated steel with porous bronze sintered on the steel and polymers (pom) embedded into the bores of the bronze. By combining the metals and the polymers together, its products are endowed with a lower friction coefficient and good capacity of anti-abrasion and self-lubrication. Moreover, the steel back is plated with an erosion-prevention layer. Products of the Pom composite series are widely applied in printing, weaving, and tobacco-producing machines, gymnastic equipment, etc.

Wear-resistant
Self-Lubricating Multilayer Composite Bushing is of excellent anti-abrasion performance, mainly due to the particular molecule structure of POM. The abrasion process can be generally divided into three phases, so there are kinds of friction coefficients. See the right graph:
1. “Running-in” phrase: POM compound on the bushing is transferred to its mating surface and forms a lubricating film. At this phase, the friction coefficient is bigger, thus the abrasion pace is very quick. See the curve shown in area I of the graph.
2. “Stabilization” abrasion phrase: After the “Running-in phase”, the friction happens between POM and POM, thus the friction coefficient is smaller and keeps steady. As a result, the wear rate is low and steady. See the curve shown in areaⅡof the graph.
3. “Sharp” abrasion phrase: As POM in the porous layer is slowly consumed up, not enough lubricant can be supplied to the gliding media. The friction coefficient and wear rate will rapidly rise. When 70% of the bronze surface is exposed, the service life of Self-Lubricating Multilayer Composite Bushing closes to its end. See the curve shown in area Ⅲof the graph.
