Self-lubricating bearings with different metal materials
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 an oil film. So it is suitable for high temperatures. heavy duty, anti-corrosion, or where it is hard to be introduced. Its performance doubles both on hardneswear wears friction. It is now widely applied in successive casting machines, steel rollers in metallography, mineral machine, ships, steam turbine, hydraulic turbines, and injection molding machines for plastics.
Suitable for low load position, wear performance worsens greatly when under middle or high load Can be applied in furnace door linage, furnace, conveyor, tool machines, light industries, etc.
Suitable for low load position wear performance worsens when under middle or high load. The mating layer is the same as JDB-2 so that more cost-saving than JDB-2 whereas compression strength increases and is weldable. Most suitable for a dry position in the construction, metallurgical machines, conveyor machines, etc.
Very good performance when under low load. Not suitable for middle and high load. Atypical cost-saving material. Can substitute JDB-4 to be applied in the position without high requirements such as die guider, plastic injection machines, etc.
Can be used under low, middle, and high loads. Due to its superb high hardness, when under high load, it over-performs another JDB-5 type. Not suitable for water. Acid, alkali circumstances Most suitable for the supporting position of hoisting machine, e. g. bulldozer supporter, hoister supporter, reeling machine supporter, etc.
