Features
Unlike solid linear shaft rod optical shafts, hollow linear rod can reduce weight and improve bending and torsional resistance, with better strength-to-density ratio and specific stiffness, suitable for CNC, 3D printer, automatic machinery, injection molding machine, engraving machine
Tolerance Metric h7, hardness about HRC 58-60, hardening depth 0.8-3mm, straightness≤ 0.07/1000mm, chrome thickness 0.015mm-0.02mm, roundness no more than 3μm, surface roughness ra0.1m - 0.35m
Adapting C45 high quality carbon steel, high frequency quenching, surface chromium plating. Using mirror polishing technology, more durable and corrosion-resistant.
Humanization Design Chamfer on both ends, easier to install linear bearings and won't hurt fingers when installing it
We can customize the linear rail, including the length and end processing, showed as image 3.With full series of diameters 5, 6, 8, 10, 12, 13, 14, 16, 20, 25, 30, 35, 40, 50mm and so on, any special needs, please give us message
