Life Factors & Sleeve Bushing Application
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.
- Ambient Temperature: The higher the working temperature is, the shorter the life of the products would be.
- 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.
