Oil cylinder and construction machinery applicatio

Product name: PM Sintered Joint Bushing

Mechanical properties

 

Characteristic

Using the iron and copper alloys as the main raw materials and applying PM sintering craft

Solid lubricants like graphite inside the material, treated with oil impregnation to guarantee the lower wear rate even without oil

 Owing higher load and superior wear resistance conparaed to traditional PM bushings

 

Application

Hydraulic cylinders, construction machines, loaders, crane and agricultural machines.
