Chrome-Plated Shaft SFC 8

Chrome-Plated Induction-Hardened Ground Shafts

Chrome-plated induction-hardened shafts are manufactured from CK 55 material. They have a surface hardness of 62+/-2 HRC. In particular, low surface hardness in linear bearing applications (55 HRC piston shaft, only non-chrome-plated induction-hardened shafts, mercury steel, etc.) prevents scratching on the shaft. For this reason, the bearing cannot operate on a clean surface and deteriorates quickly. The middle part of the shafts has normal hardness, and it is possible to reach the normal hardness body by cutting teeth in the middle or removing chips from the hard outer surface. Additionally, SK series or SHF series aluminum bearings are used in the bearing of the shafts.
