Availability:

       Cylindrical bushes, thrust washers, strip and nonstandard parts as the clients supplied drawing etc.

Tolerance:

      General recommended seat hole tolerance for the H7, shaft diameter tolerance is f7.

Material Structure:

      The same produce process and application except overlay the solid lubricants into the diamond shaped lubrication indents on the bearing surface, which will offer good friction at the start and process works and keep good condition even no oil giving at short time. So can be used in construction machines, gears, automotive clutch pads etc.
