1 no oil lubrication oil lubrication or less, difficult to apply to the oil or refuel the occasion, you can not care when using less maintenance; 2 good wear resistance, low friction, long service life; 3 in within the range of -195 ℃ ~ +280 ℃ use; 4 go well together performance, low noise, no pollution; 5 thin-walled structure, light weight, can reduce mechanical volume; 6 transfer film can be formed at the time of the operation, played The protective effect of grinding shaft, no bite shaft phenomenon; 7 low hardness of grinding axes, axes without quenching can be used, thereby reducing the processing difficulty related parts; 8 no water, oil absorption, thermal expansion coefficient, heat resistance, dimensional stability; 9 on the back of a variety of metals can be plated steel, and therefore can be used in corrosive media, will not rust; has been widely used in various mechanical sliding parts, such as automated machinery equipment (stretching, swinging, sliding, bending, swing, swing parts) hydraulic cylinder bushings, gear pumps, textile machinery, vending machines, plastic molding machines, die-casting machine, rubber machinery, tobacco machines, fitness equipment, office machinery , pallet trucks, automobiles, motorcycles, agricultural and forestry machinery.
