Modified PTFE Composites

ZYS is the earliest unit in China which developed and produced PTFE solid self-lubricating bearing cage materials for the space long March series rocket turbine pump engine, satellite detection infrared horizon sensor, and many other national key supporting projects. ZYS has the mature independent research and development ability, the inspection method and the capacity of batch production for Modified PTFE Composites.

Description

Features of Modified PTFE Composites:

Modified PTFE Composites is to add filler (such as metal powder, reinforced fiber, solid lubricating material) to PTFE, so as to improve and overcome the defects of large expansion coefficient, low hardness, poor wear resistance and thermal conductivity on the basis of maintaining its original advantages and also improve its comprehensive performance using compounding effect.

Lubrication mechanism of Modified PTFE Composites:

The lubricating mechanism of the composite material is that a transfer lubricating film is formed on the rolling body and the raceway through mutual friction between the rolling body and the cage pocket during the running process, so that the friction between the cage and the steel ball and the raceway is converted into friction between the cage materials, which can reduce the friction coefficient and wear and prolong the bearing service life.

Application field of Modified PTFE Composites:

ZYS is the earliest unit in China which developed and produced PTFE solid self-lubricating bearing cage materials for the space long March series rocket turbine pump engine, satellite detection infrared horizon sensor, and many other national key supporting projects. ZYS has the mature independent research and development ability, the inspection method and the capacity of batch production.

Typical application conditions of Modified PTFE Composites are ultra-low temperature (-253 ℃), high speed, heavy load, DN value can be up to 2.4 million.
