Life Factors & Sleeve Bushing Application

  1. PV Value:

    PV value is an effective criterion to calculate the service life of sleeve bushing. If there is need to prolong the service Life, PV value must be reduced.

  2. Ambient Temperature: The higher the working temperature is, the shorter the life of the products would be.
  3. Quality of the Mating Surface:Sleeve bushing service life can be obviously prolonged if its mating axis is made by alloy steel or is plated by hard chrome and with surface Roughness Ra=0.4~0.63.

Application: he printing, woven, tobacco and gymnastic machinery, shock absorber etc..

* By combining the metals and the polymers together, its products are endowed with the lower friction coefficient and good capacity of anti-abrasion and self-lubrication. Moreover, the steel back is plated with an erosion-prevention layer. Steel backed with copper-plated steel with porous bronze sintered on the steel and (PTFE+Pb) imbedded into the bores of the bronze.
