JFB Flange Oilless Bushing – Graphite Bearing – Unique Oilless Metal Bronze Structure
Low Friction Embedded Sleeve Bearings, maintenance-free, Graphite Manganese Bronze bushing metric size. Material CuZn25A16Fe3Mn3 for 300℃
Solid inlaid bearings are on a high force brass substrate.
Inlaid with graphite or MoS₂ solid lubricant, a high-performance solid lubrication product.
It breaks through the limitation of general bearing relying on oil film lubrication.
In the process of use, through friction heat to make solid lubrication and shaft friction, the formation of oil, and powder coexist lubrication excellent conditions, not only protect the shaft does not wear and make the solid lubrication characteristics eternal.
Its hardness is twice as high as the general copper sleeve, and its wear-resisting performance is twice as high.
At present, it has been widely used in a metallurgical continuous casting machine, train support, steel rolling equipment, mining machinery, ships, turbine, and other high temperature, high loads, low speed, and heavy loads occasions.
Manganese Bronze bushing can be manufactured individually, up to 800 kg in weight and 1500 mm in diameter.

Bearing Introduction:
JFB solid inlaid self-lubricating bearings are designed with flanges to limit the axial movement of the bushing. The product is a high-performance solid lubrication product inlaid with graphite and MoS2 compound solid lubricant on a copper alloy matrix. It breaks through the limitation of general bearing relying on oil film lubrication. In the process of use, through friction heat to make solid lubricant and shaft friction, oil, powder coexist lubrication excellent conditions, not only preserve the shaft wear but also make the solid lubrication characteristics eternal. Its hardness is twice as high as the general copper sleeve, and its wear-resisting performance is twice as high. At present, it has been widely used in metallurgy casting machines, train support, steel rolling equipment, mining machinery, ships, gas turbines, and other high temperature, high load, low speed, and heavy load occasions.

Engineered for a Longer More Reliable Service Life, Metric flange bronze bushing.
Graphite Manganese Bronze bushing, also known as brass graphite bearing, is a special material self-lubricating bearing, according to different uses and working conditions, choose different copper graphite bearings. One of the major categories of solid inlaid copper graphite bearings (JDB for short) is a novel lubricating bearing with both the characteristics of metal bearings and oil-free lubricating bearings. The metal matrix bears the load, and the solid lubricating material with special formula plays the role of lubrication. It has the characteristics of high bearing capacity, impact resistance, high-temperature resistance, strong self-lubrication ability, especially suitable for heavy load, low speed, reciprocating or swing, and other difficult lubrication and oil film formation occasions, also not afraid of water and other acid erosion and scouring. At present, the products have been widely used in a metallurgical continuous casting machines, rolling equipment, mining machinery, ships, steam turbines, water turbines, injection molding machines,s and equipment production lines.

Application of Manganese Bronze Bushings :
● It is difficult to form lubricating oil film under low speed and heavy load.
● Bad environment, limited structure, not easy to add lubricating oil.
● The large temperature difference in the working environment.
● The maintenance is difficult and the long life of the bearing is required.
● When used in corrosive media.
● When impact load is easy to occur.
