Detailed description

JDB solid lubricating bearings in the friction surface of the metal substrate bearing out the appropriate size, arranged in order of the hole, and then embedded in the cavity has a unique self-lubricating properties of forming a solid lubricant (solid lubricant area is generally friction area 25 % to 35%) and made of self-lubricating bearings. This bearing combines the respective advantages of metal matrix and specially formulated lubricating materials, breaks through the general bearing rely on oil film lubrication limitations. JDB solid lubricating bearings are particularly suitable for oil-free, high-temperature, high-load, low-speed, anti-fouling, corrosion, radiation, as well as under vacuum solution in water or infiltration impossible lubricating film using special working conditions. The products are widely used in metallurgy rolling equipment, filling equipment, turbines, gas turbines, instrumentation, and mining machinery, shipbuilding, machinery, textile machinery, shipbuilding industry, space navigation and other fields. But also more and more widely used in other industrial and agricultural machinery. Matrix JDB solid lubricating bearings bearing itself should be based on working conditions may be. Commonly used materials are high-strength brass, bronze, castings. The bearing their own working conditions, through a combination of different metal matrix and the embedded solid lubricant, can guarantee products to meet the special needs of a variety of temperature, load, exercise and other media working conditions, while ensuring stable and reliable work.

Application Features

JDB-5 is an enhanced product, it has a very high compression performance, particularly adapted to support in lifting machinery parts, for example: Excavators supported hoist supported crane support and so on. However, due to the matrix of the steel, so should not be used in water or acid, alkali occasions.

Available forms

JF Bimetallic composite bearings to high-quality low-carbon steel substrate, the surface of the sintered copper alloy with low friction characteristics (CuPb10Sn10, CuPb6Sn6Zn3, CuPb24Sn4, CuPb30, AlSn20Cu, CuSn8Ni) as bearing wear layer, copper alloy surface may need to use conditions processing of various types of tank, hole, oil hole and so on......
