    SF-1W(P4)

    1. Detailed information

    SF - 1 w (P4) high-performance oilless bearing, environmental protection is based on steel substrate, the middle bronze powder, sintered spherical surface rolling four ethylene (PTFE) and a mixture of green polymer material, rolling and sliding bearing. Product is lead-free environmental protection, wear-resisting performance is excellent, plastic layer and copper layer with high strength, fatigue resistance, impact resistant performance is good wait for an advantage, has been completely replace my company SF, 1 x, SF, 1 t, SF, 1 p, SF - 10 oil-free bearings. The product after two years of testing and trial, the customer reflects well. It has been successfully passed the 1 million test of the CBK1 pump of the changjiang hydraulic parts plant and the 1 million test of the shagawa shock absorber, and the plastic layer of the sleeve surface is kept intact after the test, which is basically unworn. This product is a new product of our original company, and the quality level is in the leading position in China.
