The oil-free bearing is a novel lubricating bearing with both the characteristics of metal bearings and the characteristics of oil-free bearings. The metal matrix bears the load and the specially formulated solid lubricating material acts as a lubricant. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, strong self-lubricating ability, etc. It is especially suitable for occasions where it is difficult to lubricate and form oil film, such as heavy load, low speed, reciprocating or swinging, and is not afraid of water leaching and other acid etching. And scouring.
