CRB850BM

金属基轴承 — CRB850BM

基材特性：

CRB850BM以金属为基体表面烧结有固体润滑剂的铜合金粉，由于润滑集弥散于工作表面因此润滑性更为充分。适用于高载低速而无法加油或无法形成润滑的场合，并具有较好的耐酸、碱性。产品被广泛用于水轮机，注塑机、汽车轮胎模具等。同时CRB还可以提供CRB850S整体烧结型产品。

结构

Bearing surface

典型应用

Metal backed with bronze graphite oilless bearings

1.Sinter bronze powder with graphite: good wear resistance with lower friction and excellent load carrying capacity. Can be machined after fitting to get precision tolerance. CSB also can supply the bearings with PTFE or graphite sprayed layer on the work surface to get much lower start friction.
2. Metal backing: gives exceptionally high load carrying capacity, excellent heat dissipation.
3.Copper plating 0.002mm, good corrosion resistance.

The standard bearings we supply as plain surface, also we supply with cleaning grooves for small angular movements or in the presence of abrasive media or dirt, and indented surface for grease lubricated applications.

Indented surface for grease lubricated applications.

Cleaning grooves for small angular movements or in the presence of abrasive media or dirt.

The special structure of the material suitable for hostile environments, for high load application which lubrication is difficult. Now CSB850BM has been widely used in water turbines, vane controls, injection molding machinery, packing machines, construction equipment, tire moulds, paper production machinery, furnace expansion plates, automotive transmission, heavy lifting chain linkage, food production equipment etc.
