Bi-metal Fe-Ni Sintered Alloy with Solid Lubricants


Suitability for motions of in any direction due to its solid uniform lubricant, with high performance even for micro-range motions. It is suitable for self-lubrication work condition, we recommend pre-lubricated if possible, for dry starts, future lubrication however, would be drastically reduced. It has very good load capacity, good wear resistance and low friction. The bearing can be machined again after the parts fixed to achieve tighter tolerance.

CSB850 is a solid 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 tie-bar bearings, construction machines etc.

Typical Applications

This material has been widely used in high load with tower 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. See more about bi-metal bushing / sliding bearing applications "CLICK HERE"
