Precision Steel Shafts

Precision Steel Shafts

Induction hardened and ground precision steel shafts for use with linear bearings. We cut and match to your requirements

Induction hardened and precision-ground shafts for linear motion applications providing the inner race for Ball Bushing bearings. All shafts are manufactured to extremely close tolerances for surface finish, roundness, hardness and straightness to provide long service life with reduced maintenance.


Shafts are made from high quality carbon steel and induction hardened to HRC 60-64. Heat treatment on specialized equipment assures uniformity of hardness. The minimum depth of hardness is carefully controlled to provide the high load carrying capability of Ball Bushing bearings.


Shafts are precision-ground to the extremely close diameter tolerance of h6. Diametral accuracy is an important factor when using Ball Bushing bearings. It assures dependable diametral fit-up when minimum clearance is required.


Hardness: HRC 60-64
Surface Finish:
Standard (Ra) 0.32um except on machined or annealed surfaces.


Standard length tolerance on cut-to-length shafts is ± 0.5 mm. Special length tolerances are available upon request.


Standard chamfer on shaft diameters is 1.0mm x 45º.
Other chamfers can be supplied upon request.

Available as:
