PRECISION SHAFTSTECHNICAL DATA1. OverviewMiniTec precision shafts for linear bearings are available from stock in all current diameters.Furthermore, we have an extensive inventory of intermediate sizes, special variants, and materials.All quality parameters are optimally selected for use in linear guides.Surface roughness: Ra 0,15 µm to 0,3 µm = Rz 1,25 µm to 2,5 µm(see following pages for further details)Diameter tolerance:Circularity:Straightness:up to 100 mm: h6Hard chrome plated variant: h7for SM linear bearings of high-precision applications: g6(see following pages for further details)< 1/2 tolerance per DIN ISO 286-2 (tolerance range)< Ø 10 mm: < = 0.3 mm/mfrom Ø 10 mm to Ø 20 mm: < = 0,2 mm/mØ 20 mm and up: < = 0,1 mm/m(see following pages for further details)Materials:Standard Heat-treated steel, e.g. Cf53 (1.1213) - HRC 60-66Miniature shafts Ø 3 and Ø 4 100 Cr6 (W-Nr. 1.3505) - HRC 58-63X90 (W-Nr. 1.1112) - HRC 53-60Hollow shafts 100 Cr6 (W-Nr. 1.3505) - HRC 58-63Special material with increased grain strength 42CrMo4 heat-treated (W-Nr. 1.7225) HRC 53-61(not in stock)Corrosion-resistant shafts X46Cr13 (W-Nr. 1.4034) - HRC 52-55X90CrMoV18 (W-Nr. 1.4112) - HRC 53-60X105CrMo17 (W-Nr. 1.4125) - HRC 53-60Hard chrome-plated shafts Cf53 (W-Nr. 1.1213)Chrome layer thickness: 0,008 bis 0,015,Layer hardness: HRC 65 - 70(see following pages for further details)MiniTec precision shafts are protected by anticorrosives.
