RST-JDB-1 solid lubricant embedded bushing is a new type made from strong brass and homogeneously embedded with solid lubricant in its body. It breaks through the limit of general bearing whose lubrication depends on oil film. So it is suitable for high temperature, heavy load, anti-corrosion, or where oil is hard to be introduced. It performs doubles both on hardness and wear-friction. It is now widely applied in successive casting machines, steel rollers in metallography, mineral machine, ships, steam turbine, and injection molding machines for plastics.
RST-JDB-2 suitable for low load position, wear performance worsens greatly when under middle or high load, it can be applied in furnace door linage, furnace, conveyor, tool machines, light industries, etc.
RST-JDB-3 suitable for low load position, wear performance worsens when under middle or high load. The mating layer is same as RST-JDB-2 so that more cost-saving than RST-JDB-2 whereas compression strength increases and weldable. Most suitable for dry position in construction machinery, metallurgical machines, conveyor machines etc.
RST-JDB-4 very good performance when under low load. Not suitable for middle and high load. A typical cost saving material. Can substitute RST-JDB-4, applied in the position without high requirements such as die guider, plastic injection machines etc.
RST-JDB-5 can be used under low speed rotation, middle and high load. Due to its super high hardness, when under high load, it over performs than other RST-JDB type. Not suitable for water. Acid, alkali circumstances. Most suitable for the supporting position of hoisting machine,e,g. Bulldozer supporter, hoister supporter, Crane supporter etc.
