Why are oil-free bearings widely used?

- Oct 08, 2018-

1, Oil-free Bearings It is well known that the smooth operation of all machinery must use some kind of bearing. Oil-free bearing is a kind of new lubricating bearing with the characteristics of metal bearing and oil-free lubricating bearing, which is loaded by the metal matrix, and the special formula of the solid lubricating material is Lubricated. It has high load-bearing capacity, impact resistance, High temperature, self-lubricating capacity and other characteristics, especially suitable for heavy-duty, low-speed, reciprocating or oscillating, such as difficult to lubricate and form oil film, but also not afraid of water and other acid leaching and erosion. The majority of users generally reflect the mosaic bearing not only fuel saving, energy conservation, and its working life is also longer than ordinary plain bearings. 


2. Oil-free bearing the product is made of a mixture of steel plate, sintered spherical bronze powder, surface rolled PTFE and Lead. It has a small coefficient of friction, abrasion and corrosion resistance. oil-free self-lubricating and long service life characteristics, use it can reduce costs, reduce noise, prevent sticking, slippery. Oil-free Bearings 


3, metal-based solid Inlay Oil-free bearings. On the metal substrate, a high-performance solid lubricant product with graphite and MoS2 composite solid lubricants is Embedded. It breaks through the limitations of general bearings depending on oil film Lubrication. In the use of the process, the solid lubricant by friction with the shaft friction, the formation of oil, powder and lubrication of excellent conditions, both the preservation of the shaft does not wear, but also make the solid lubrication characteristics of the Eternal. It has a hardness higher than the average copper set, and wear resistance is also one times higher. has been widely used in metallurgical continuous casting machine, train support, rolling equipment, mining machinery, ships, gas turbines, such as high temperature, High current carrying, low-speed heavy loads and other occasions. 


4, Multilayer Composite Oil-free bearings. With steel plate as the matrix, intermediate sintered spherical bronze powder, surface rolled PTFE and lead mixture, is a rolling plain bearing. It has the characteristics of small friction coefficient, abrasion resistance, good corrosion resistance and no oil lubrication. It can reduce the cost, reduce the mechanical volume, avoid the phenomenon of biting shaft and reduce the mechanical noise. Products have been widely used in a variety of mechanical sliding parts, such as printing presses, lifts, textile machines, Tobacco machine, Fitness equipment, hydraulic trucks, micro-motors, solenoid valves, automobiles, Motorcycles and Home machinery. Oil-free bearings have been widely used in accordance with the Advantages. ...
