The same produce process and application as WB type material 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 parts etc
1.Easy of fitting and lubrication
2. High load capacity
3. Excellent wear resistance with lower friction
4. High level thermal conductivity
5. Minimum overall dimensions
6. Chemical resistance
7. Can be worked under dry/marginal lubrication at short time, have much lower friction factor at initial moving
Initial pre-lubrication at assembly required...

This type of bushing is widely applied in hoisting machines and other construction machines, automobiles, tractors, trucks, machines tools and some mineral engines.
