Bosch Rexroth 0.8m Long Aluminium, Steel Round Shaft, 20mm Shaft Diam. , Hardness 60HRC, h6 Tolerance

Precision steel shaft with ready-mounted aluminium shaft support rails, flanged, extremely high height tolerance

For use with open Linear Bushings
For long guides or high loads where self-supporting shafts cannot be used due to shaft warping
Unlimited length when using interconnecting shafts
Support rails for various requirements
Additional degrees of freedom in circumferential direction compared to profiled guide rails.
For applications where other linear guides tend to warp due to imprecise substructure
Shaft support rail material: Aluminium
Combined with Linear Sets, these shaft support rails can be used to create linear guides with very low height.
Extra rigidity. Carefully adapting the support rail to the Linear Bushing size produces the ideal pressure angle for fitting the shaft which, along with the large fastening bolts, ensures extra rigidity.
