FB09G Bronze base rolling bearings
And FB090 have the same production process and use of occasions, but in its diamond-shaped oil hole filled with graphite-based solid lubricant, the product in the initial use of the stage and the process can have a lower friction factor in the short break Oil in the case can still maintain a good working condition. It is widely used in construction machinery, gearbox transmission components, such as high-speed steam locomotives clutch medium-speed parts.

FB09G material deconstruction
- Using high-density bronze roll forming or spherical oil pockets, oil hole special internal surface to reduce the wear and tear to extend the use of time and good anti-corrosion function.
The advantages of the product
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.
