Product Description
JDB sliding oilless bearing is a kind of solid lubricant embedded bushing,which is a new type made from strong brass and homogeneously embedded with solid lubricant in its body.It breaks through the limit of general bearing whose lubrication depends on oil film.So it is suitable for high temperature,heavy duty,anti-corrosion and the working conditions where oil is hard to be introduced.Its performance doubles both on hardness and wear-friction.
