Support Rial Shaft STBR/ SBR-B

Support Rial Shaft STBR/ SBR-B
ISUTAMI STBR/ SBR-B shaft support rail, also known as STBR/ SBR-B support rail unit, is a metric unit shaft rail assembly that combines a support rail and a linear shaft pre-mounted on the rail. The support rails are used for continuous shafting support, which provides an easy way to fully support the shaft along its length, and can be used horizontally or vertically. They are available in several different types based on the application loading and envelope needs. These supports come standard available from stock and are made to simplify shaft mounting. The shaft support eliminates a lot of the problems encountered in designing and manufacturing custom shaft support devices. Unlimited stroke length and mounting hole flexibility are another reason why ISUTAMI support rails are suitable for any application.

Support Rial Shaft STBR/ SBR-B Features

The material of STBR/ SBR-B support rail is generally aluminum or stainless steel, which is corrosion resistant and can be used with S solid linear shaft or SP hollow linear shaft. The diameter of the supporting linear shaft is 16-30mm, and the overall width (W) is 50- 60mm, flange height (T) range 6-7mm, flange mounting diameter (S1) range 5.5-6.5mm, center distance can be customized according to 25mm, fixed shaft screw size (S2) range is M5-M5. The STBR/SBR-B shaft rail combination can be divided into any length according to customer requirements. Suitable for open-type linear ball bushings or open-type linear bearing housings with an opening degree (θ) of 50° or 60°. ISUTAMI can provide a simple linear positioning system with a metric linear bearing housing for the shaft support.
Supporting Asian metric series open linear bearing pillow blocks: SME open linear bearing pillow block, SME-L extended open linear bearing pillow block, TBR adjustment opening type linear bearing pillow block, etc.;
Supporting European metric series open linear bearing pillow blocks: KBE open linear bearing pillow block, KBB-OP open linear bearing pillow block.

Technical Notes
For open linear bushings, ensures a very rigid and stiff system.
The shaft is pre-mounted to the shaft support rail.
Standard lengths are shown which allow the distance to the first and last hole to be equal. Different holes pitches available on request.
