Thrust Washer Wear-resistant

Thrust Washer is of excellent anti-abrasion performance, mainly due to the particular molecule structure of PTFE. The abrasion process can be generally divided into three phases, so 3 kinds of friction coefficient. See the right graph:

  1. “Running-in” phrase: PTFE 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 showed in area I of the graph.
  2. “Stabilization” abrasion phrase: After the “Running-in phase”, the friction happens between PTFE and PTFE, thus the friction coefficient is smaller and keeps steady. As a result, the wear rate is low and steady. See the curve showed in areaⅡof the graph.
  3. “Sharp” abrasion phrase: As PTFE in the porous layer is slowly consumed up, not enough lubricant can be supplied to the gliding media. Friction coefficient and wear rate will rapidly rise. When 70% of the bronze surface is exposed, service life of Thrust Washer closes to its end. See the curve showed in area Ⅲof the graph.
