Specifications:
The document outlines the specifications for linear shafts used in ballscrew manufacturing, made from 50CRMO4 Q+T W.NR. 1.7228 material. The shafts are available in various diameters ranging from 40 mm to 160 mm, with corresponding weights from 9.87 Kg/m to 157.75 Kg/m. The ISO tolerance is h6, with a surface finish of 0.20 to 0.25 μ RA. The shafts have a straightness of 0.2 mm/m, roundness of 3 μ max, and conicity of 3 μ max. Lengths vary from 6200 mm to 12000 mm, depending on the diameter.

Mechanical Properties:
The shafts are hot rolled and quenched and tempered (Q+T) according to EN 10083-3: 2006 standards. They have a tensile strength (R) of 800 to 1100 N/mm², a yield strength (Rp 0.2) of at least 600 N/mm², and an elongation (A%) of at least 10%. The hardness is between 270 and 300 HB, with a minimum impact energy (Kv) of 30 J.

Chemical Composition:
The chemical analysis specifies the following composition: Carbon (C) 0.46 - 0.54%, Silicon (Si) max 0.4%, Manganese (Mn) 0.50 - 0.80%, Phosphorus (P) max 0.025%, Sulfur (S) max 0.035%, Chromium (Cr) 0.90 - 1.20%, and Molybdenum (Mo) 0.15 - 0.30%.
