SBR aluminium linear motion ball bearing housing linear bearing slide unit bushing case SBR20 SBR 30 SBR40

Slide Units(SBR &TBR). Its internal bearing is an open linear bearing. We have two types of slide units, which are integrated of open type aluminium housing and open type linear bearing, and the slide units needs to be used in combination with the shaft support.

SBR series linear block and linear shaft supprt

the linear bearing inner dia from 10mm to 50mm,

the linear shaft dia is the same as linear bearings,

the linear block case have standard SBR-S series:

SBR10UU, SBR12UU, SBR13UU, SBR16UU,SBR20UU, SBR25UU,SBR30UU,SBR40UU,SBR50UU

have the over-length block SBR-L series:SBR10LUU, SBR12LUU,SBR13LUU,SBR16LUU,SBR20LUU,SBR25LUU,

SBR30LUU,SBR40LUU,SBR50LUU

TBR series linear block and linear shaft supprt

the linear bearing inner dia from 16mm to 30mm, the linear shaft dia is the same as linear bearings

The linear block case have standard TBR-S series:TBR16UU,TBR20UU,TBR25UU,TBR30UU

Have the over-length block TBR-L series:TBR16LUU, TBR20LUU,TBR25LUU,TBR30LUU

Comparing to SBR and TBR, the main difference is that SBR block can just be mounted from up to down, But TBR block can be mounted from up to down, also down to up,SBR rail width is less than TBR rail width

However, SBR blocks and TBR blocks can be interchanged into the same linear guide, The rail linear shaft have two material:S45C and GCr15(SUJ2)
