Product Description

Sintered Porous Metal Bearings are powder metallurgical parts, the starting materials are obviously metal powder. The metal powder used are specifically produced to give flow and compacting characterristics and at the same time ensure best mechanical strength, grade or porosity for oil retention and self lubrication in its finished form.

Sequence of production:

Forming ( or compacting), Sintering, Sizimg, Oil Impergnation
