Cylindrical guideways, polished shaft

Precise hardened, polished shafts of high quality heat-treated steel. Hardness is 59-65 HRC. Length is up to 3000mm. The diameters - of 4 to 100mm. Special tolerances, diameters and lengths - by the customer request. It is also possible to realize the mechanical treatment of precise shafts according to the drawings.


Main characteristics of polished precise shafts

Precise shafts are made ​​of high quality steel with a hardened and polished surface, whereby they achieve a high dimensional accuracy and surface hardness. For example, stainless steel shafts are used in the case of application in a chemically aggressive environment, and the linear cylindrical shafts are subjected to chromium plating for the corrosion protection. All precise shafts have an diameter accuracy with the tolerance of h6 and h7. Due to induction hardening we get the uniform hardness of surface layer, and by the subsequent polishing we achieve a high dimensional accuracy of the shaft.
