1.Sinter bronze -- Liner material: CuPb10Sn10 DIN-CuPb10Sn, 

SAE-797, JIS-LBC3, GGB-SY, GLYCO-66, FEDERAL MOGUL-HF2, 

DAIDO-L10, ACL-F100. Alloy Hardness: 69-90 HB

Good wear resistance with lower friction and excellent load carrying capacity.

Bimetallic bushing can be machined after fitting to get precision tolerance. 

We also can supply the bearings with PTFE or graphite sprayed layer 

on the work surface to get much lower start friction.

2. metal backing --low carbon steel: gives exceptionally high load carrying capacity,

excellent heat dissipation.

3.Copper plating 0.002mm, good corrosion resistance.
