Solid and hollow shafts are high precision shafts made from quenched and tempered steel to rolling bearing quality and are supplied in metric sizes. The material quality of the shafts guarantees high dimensional and geometrical accuracy (roundness, parallelism). Due to their high surface hardness and surface quality, the shafts are highly suitable as precision raceways for linear ball bearings. Shafts made from Cf53 (material number 1.1213) are induction hardened and ground; the surface hardness is 670 HV + 165 HV (59 HRC + 6 HRC). Shafts are also possible in corrosion-resistant steel material.
