Oil-free bearing is a new type of lubricating bearing with metal bearing characteristics and oil-free lubricating bearing characteristics. It is carried by a metal matrix and lubricated by a specially formulated solid lubricating material.

It has the characteristics of high carrying capacity, impact resistance, high temperature resistance, and strong self-lubricating ability.It is especially suitable for heavy-duty, low-speed, reciprocating or swinging occasions where it is difficult to lubricate and form an oil film, and it is not afraid of acid erosion and scouring such as water flushing.

It is widely used in metallurgical continuous casters, rolling equipment, mining machinery, ships, steam turbines, water turbines, injection molding machines and equipment production lines.

Oil-free bearings refer to bearings that can work normally without oil or less oil, rather than without oil at all.
