What are self-lubricating bearings?

Self-lubricating bearings are also called graphite copper sleeves. They are based on metal materials and use graphite and silver disulfide as solid lubricants. They are made through a special process so that the solid lubricants have uniform gaps and can contain a certain amount of lubricating oil. , when working under oil-free conditions, the lubricating oil and solid lubricant are combined through friction heat and gradually distributed to the friction surface to achieve the effects of small friction coefficient and good wear resistance.

Self-lubricating bearings are universal basic product accessories that can adapt well to complex environments such as high pressure, low pressure, high temperature, low temperature, oil lubrication, oil-free lubrication or water lubrication. The base body of self-lubricating bearings is high-strength brass, which is twice as hard as ordinary copper sleeves and more than doubles in wear resistance.

Self-lubricating bearings are also widely used in adapting equipment, such as mining machinery, locomotive supports, steel rolling equipment, ship machinery, mold equipment, textile machinery, gas turbines and other low-speed heavy loads, high-speed light loads and other occasions.

As a bearing manufacturer with more than ten years of production and R&D experience, Mingxu Bearing focuses on the manufacturing and R&D of solid self-lubricating wear-resistant parts. It has developed high-temperature-resistant maintenance-free bearings, heavy-duty oil-free bearings and high-impact bearings. Strength slides and other product series. Product manufacturing uses modern automated equipment and strictly implements ISO2000 quality management system standards. The main processes are completed by high-precision CNC machine tools. The company's main products include JDB solid inlaid self-lubricating bearings, steel-copper sintered bearings, SF-1 self-lubricating bearings, SF-2 boundary self-lubricating bearings, FB090 copper bearings and a series of products, which have reached the level of "domestic leading and internationally advanced" , helping customers break through industry technical barriers many times and achieve the leap from "Made in China" to "Intelligent Manufacturing in China". Up to now, the company's products are distributed in all major provinces in China and exported to many overseas countries, and are deeply recognized and loved by customers at home and abroad.
