【zx-70 self-lubricating composite material】
this material grade is zx-70, with high strength special synthetic fiber as reinforcing material, reinforced modified polyester resin as base material, and adding solid self-lubricant powder, high strength composite material synthesized by advanced technology under certain temperature and pressure.
excellent dimensional stability, excellent wear resistance, can work in the state of little or no oil has a prominent advantage. excellent self-lubrication, high load. it has a very low coefficient of friction in dry state to reduce the wobble and creep, and is suitable for long-stroke oil cylinders.
