Oil-free bearings have the characteristics of high load carrying capacity, impact resistance, high temperature resistance, and strong self-lubricating ability. They are especially suitable for heavy loads, low speeds, reciprocating or swinging situations that are difficult to lubricate and form an oil film. They are not afraid of water wash and other acids. Erosion and erosion. The majority of users generally reflect that inlaid bearings not only save oil and energy, but also have a longer working life than ordinary sliding bearings. At present, the products have been widely used in metallurgical continuous casting machines, steel rolling equipment, mining machinery, ships, steam turbines, water turbines, injection molding machines and equipment production lines.
