Solid or hollow shafts

SKF precision shafts can be supplied either as solid or hollow shafts. The solid shafts are available in all dimensions required to fit SKF linear ball bearings; the hollow shafts have a minimum outside diameter of 16 mm. They are induction hardened and ground.

Dimensional stability

SKF shafts have exceptionally high dimensional stability and long service life. Yet at the end of shafts of normal production length, deviations of hardness and dimensional stability can occur.
For special applications, solid shafts of stainless steel or hard chromium plated shafts having a chromium layer approximately 10 µm thick can be supplied.
