With low wear rate and long life service
Additional lubrcation oil groove or oilhole, according to demand!
Cylindrical and flanged bushing, thrust washer, wear plant.
Standard or non-standard, on demand!
HLDB-JDB materials(CuZn25Al5Mn4Fe3) consist of highly wear-resistance copper cast alloy whose sliding surfaces are evenly provided with a certain percentage of solid lubricant plugs according to work condition. High-strength copper alloy provides a high load-bearing capacity and the solid lubricant can be formation of low friction film. Under technical dry running conditions, the bearing surface is designed with thick running-in film which enables the solid lubricant to be transferred to the counter material at the first contact.
|Material ||CuZn25Al15Mn4Fe3||Tensile strength||>750N/mm2|
|Hardess HB||>210||Elongation ||>12%|
|Coefficient of linear expansion ||1.9*10-5/℃|
HLDB-JDB is widely used in automotive products line, water engineering, dam gate, plastic industries, successive casting machines, steel rollers in metallurgy industry, mineral machines, ships, turbo generators, hydraulic turbines and injection molding machines, etc.
