Self-lubricating bearings can be used in water and it is very waterproof.

Self-lubricating bearings are divided into composite self-lubricating bearings, solid embedded self-lubricating bearings, bimetal materials. Self-lubricating bearings, special materials, self-lubricating bearings, according to different water-lubricated sleeve applications and working conditions, use different self-lubricating bearings. Loaded by a metal matrix, a specially formulated solid lubricant acts as a lubricant. It has the characteristics of high bearing capacity, high impact resistance, high temperature resistance, and strong self-lubricating ability. 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 flushing. Etching and scouring of other acids. Products have been widely used in metallurgical continuous casting machine, rolling just equipment, mining machinery, molds, starting from no oil to the slider heavy machinery, textile machinery, wind power generation, ships, steam turbines, hydraulic turbines, injection molding machines and equipment production lines.
