CSB850S: Metal backed bronze powder with graphite


CSB850 is a composite multi-layer bearing composed of a special sintered material which forms the sliding surface and steel material forms the backing. Sintered layers are of a special copper-nickel alloy containing uniformly dispersed solid lubricant, the main component of which is graphite. The solid lubricants will be released at the bearing surface as wear occurs. This ensures a lower coefficient of friction during operation. In addition, these sintered layers are oil impregnated. Applications covered are automotive die wear plates, industrial robots, plastic injection moulding machine wear plates and tiebar bearings, construction machines etc.


Pertinence for motions of any direction due to solid lubricant dispersed evenly, with high performance even for micro-range motions. It is suitable for self-lubrication work condition, to aid lower start friction, we recommend pre-lubricated if possible, oiling would be drastically reduced. It has very good load capacity, good wear resistance and lower friction. The bearing can be machined again after the parts fixed to get tighter tolerance.

Typical Applications

This material has been widely used in high load withlower friction and good wear resistance requested mechanical parts where oil given is difficult such as automotive die wear plate, industrial robots, injection wear plate, injection tie-bar bushes, construction machines self-lubricating bearings etc.
