Shaft supports and bearing blocks

Shaft supports and bearing blocks fix linear shafts and ball screws to the machine frame. Their rigidity and alignment accuracy determine whether the linear axis runs smoothly and without sticking.

Shaft supports and bearing blocks - mounting without machining and axis support

You bolt ready-made supports to the plate without making seats or any additional machining, and the axis height is defined straight away. Full-length supports protect long shafts against deflection. Ball screw blocks have factory-fitted bearings, so you mount the screw quickly and with correct axial location.

SHF, SK shaft supports, shaft support rails and FK, BK, FF and BF ball screw blocks

SHF and SK end supports, the igus WAS support, full-length shaft support rails and bearing blocks for ball screws: FK and BK on the fixed side and FF and BF on the floating side, which allows for thermal expansion of the screw.

Frequently asked questions about linear shaft supports and bearing blocks

When should I use a shaft support rail instead of end supports?

For long shafts that would deflect under load. A support rail requires open linear bearings marked OP.
