Thin-Oilless
Low cost:Long life
With the development and application of new materials,Self-
lubricatingis the designers desired, high performancepolymernon-oil
bushings therefore be born. Base materials having a corrosion
resistance,dust,high compressive strength and good heat dissipation,
added fiber andfiller material with solid grease on, these ingredients
are not hierarchically arranged like traditional materials, but even
fusion.This design increasesstrength and wear resistance in order to
improve and reduce the coefficient of friction to ensure long life.

Seilf-lubricating
Solid grease, as a minor component in the reinforcing fibers embed,
when the movement, release the grease out from the fiber can help
reduce the friction coefficient.

Reinforcing fibers
Base materials mainly under radial pressure; The Support shaft, ensure
Solid grease without high load. At the same time the base materials was
added fibers and fillers to increase strength, toensure the stability of the
material.

RAfter the start-up phase
In the initial stage, running between the shaft and bushings, and gradually
form the best friction surface. Also reducing load, Worn gradual decline,
the friction coefficient is reduced; Until optimum friction Surface is formed.
