Material
- High-density bronze molding or spherical oil bag, special synthetic oil hole interior surface to reduce wear and extend the use of time to do a good anti-corrosion features.
Merit
1. save a lot of copper, copper sets car system saves hours:
2. bushes, bearing compared to its light weight and low cost;
3. The friction surface can be processed in a variety of points there, pit, storing a grease, extended refueling time is five times that of copper sets;
4. The high load capacity, especially suitable for rough friction surface;
Products available: straight sets, thrust washers, flanged bushings, bearings, skateboards, steel sleeve assembly.
