Initial assembly must be painted in the oil hold in the grease.
Application Feature:
1.Working under oilless or minim oil state,maintenance free or just need a litter maintenance.
2.Resis Abrasion,low coefficient of friction long operation life.
3.Operation in -195A C~+280A C.4). Good mending,low-noise,non-pollution.
4.Thin-walled structure,light in weight,which can reduce the machine to small size.
5.Forming a transferred film during operation to protect, safe and trouble free.
6.Low demand to the safe even no surface hardness treatment,which lower the cost of the mating components.
7.No absorption to water/oil ,small coefficient of thermal exemption,good thermal conductivity and size stability.
8.The back of the steel strip can be plated with various metals,anti-corrosion.
