Hollow Linear Shafts

Substantially lighter in weight than standard shafts, these are best for light loads. You can also run wiring, pneumatic tubing, coolants, and lubricants through the shaft's hollow center. Pair with linear bearings and shaft supports to create smooth, precise motion. These linear shafts are turned, ground, and polished to tight tolerances and hardened to resist wear.

Steel—Stronger than aluminum and stainless steel. These shafts are best for dry environments since moisture will cause them to rust.

Surface Smoothness—The lower the microinch value, the smoother the finish and the less friction it will cause on the bearing.
