 SB-BM ( DEVA - BM ) Material Specifications 

Copper coating + Metal backing + Sintered bronze powder with PTFE+ graphites


SB-BM comprises a metal shell backed with sintered copper alloy which is uniformly dispersed with graphite
and PTFE solid lubricants. The machined layer can not be exceeding the sintered layer thickness.


SB-BM material is very similar with DEVA-BM materials.


Features

1. Suitable for hostile environments and high loads and where lubrication is difficult;
2. Suitable for rotary, oscillating and linear movements;
3. Suitable for micro-range movements;
4. No electrostatic charging;
5. Has low coefficient of friction without stick-slip effects;
6. Maintenance free operation. 


Structures

1. Sinter bronze powder with PTFE+graphite: good wear resistance with lower friction and excellent load
carrying capacity. The material could be machined after fitting to get precision tolerance. CLI also can supply
the bearings with PTFE or graphite sprayed layer on the work surface to get much lower start friction.
2. Metal backing: provides exceptionally high load carryingcapacityand
3. Copper plating: thickness 0.002mm provides good corrosion resistance.
