Oil-free bearing is a novel lubricating bearing that combines the characteristics of metal bearing and oil-free lubrication bearing. The metal matrix bears the load, and the specially formulated solid lubricating material plays the role of lubrication. It is widely used in metallurgical continuous casting machines, rolling equipment, mining machinery, ships, steam turbines, water turbines, injection molding machines and equipment production lines. So, why are oil-free bearings widely used?

1. The advantages of oil-free bearings are well known, all machinery must use some kind of bearings for smooth operation. Oil-free bearing is a novel lubricating bearing that combines the characteristics of metal bearing and oil-free lubrication bearing. The metal matrix bears the load, and the specially formulated solid lubricating material plays the role of lubrication. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, and strong self-lubricating ability. It is especially suitable for heavy load, low speed, reciprocating or swinging and other occasions that are difficult to lubricate and form an oil film. It is not afraid of water wash and other acid erosion. And scour
2. Oil-free bearing This product is made of steel plate as the base body, sintered spherical bronze powder in the middle layer, and rolling the mixture of PTFE and lead on the surface. It has the characteristics of small friction coefficient, wear resistance, corrosion resistance, oil-free self-lubrication and long service life. Using it can reduce costs, reduce noise, and prevent sticking and slipping.
3. Metal base solid inlaid oil-free bearings. A high-performance solid lubricating product with graphite and MoS2 composite solid lubricants embedded on the metal matrix. It breaks through the limitations of general bearings that rely on oil film lubrication. During use, the solid lubricant is rubbed against the shaft by frictional heat to form an excellent lubrication condition for the coexistence of oil and powder, which not only protects the shaft from wear, but also makes the solid lubrication properties eternal.
4. Multi-layer composite oil-free bearings. With steel plate as the base body, spherical bronze powder is sintered in the middle, and the surface is rolled with a mixture of PTFE and lead, it is a rolling bearing. It has the characteristics of low friction coefficient, good wear resistance, good corrosion resistance and no oil lubrication. It can reduce costs, reduce mechanical volume, avoid shaft biting, and reduce mechanical noise.
