Oil free bearing (SF-1) is a novel smooth bearing with both metal bearing characteristics and oil-free smooth bearing characteristics. The metal matrix is loaded and the solid smooth data with special formula is used to smooth the bearing.
It is widely used in metallurgical continuous casting machine, steel rolling equipment, mining machinery, ships, steam turbines, water turbines, injection molding machines and equipment production lines.
Advantages of graphite copper sleeve
The advantages of oil-free bearings are well known. All machines must use some kind of bearings to run smoothly.
Oil free bearing is a new type of smooth bearing with both metal bearing characteristics and oil-free smooth bearing characteristics. The metal matrix is loaded and the solid smooth data with special formula is used to smooth the bearing.
It has the characteristics of high bearing capacity, impact resistance, high temperature resistance and strong self smoothness ability. It is especially suitable for heavy load, low speed, reciprocating or swing occasions which are difficult to smooth and form oil film. It is also not afraid of water erosion and other acid solution erosion and erosion. The majority of users reflect that inlaid bearings not only save oil and energy, but also have a longer working life than ordinary sliding bearings.
The product is made of steel plate as the base, sintered spherical bronze powder in the middle layer and rolling PTFE and lead mixture on the surface layer. It has the characteristics of small friction coefficient, wear resistance, corrosion resistance, oil-free self smoothness and long service life. It can reduce cost, reduce noise, prevent sticking and sliding.
Graphite copper sleeve
Classification of graphite copper sleeve
Metal based solid inlaid oil-free bearing
It is a kind of high performance solid smooth product inlaid with graphite and MoS2 Composite solid smooth agent on metal matrix. It breaks through the limitation of smooth oil film of general bearing. In the process of application, the solid smooth agent is rubbed with the shaft by the friction heat, forming the excellent condition of oil and powder coexisting smoothly, which not only keeps the shaft from wearing, but also makes the solid smooth property permanent.
Its hardness is twice as high as that of common copper sleeve, and its wear resistance is also twice as high. At present, it has been widely used in metallurgical continuous casting machine, train support, rolling equipment, mining machinery, ships, gas turbine and other occasions of high temperature, high load, low speed and heavy load.
Multilayer composite oil-free bearing
It is a rolling bearing with steel plate as matrix, spherical bronze powder sintered in the middle and PTFE and lead mixture on the surface. It has the characteristics of small friction coefficient, wear resistance, good corrosion resistance and oil-free smoothness.
The use of this product can reduce the cost, reduce the mechanical volume, prevent shaft biting and reduce the mechanical noise. Products have been widely used in the sliding parts of various machinery, such as printing press, elevator, textile machine, tobacco machine, fitness device, hydraulic carrier, micro motor, solenoid valve, car, motorcycle and home machinery.
