Mount directly with studs, bolts, and other threaded fasteners—no shaft supports needed. Pair with linear bearings to create smooth, precise motion. These 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.
