CNC Machine 3D Printer Round Hardened and Hard Chrome Plated Linear Transmission Steel Bearing Shaft (3mm-80mm)

High Quality Harden and Chrome Plated Linear Shaft from Professional Shaft ManufacturerLinear shaft is induction hardened, precision ground, and polished to the tolerances required by the demanding linear motion industry.1.Good finish and straightness: The surface is treated by special grinded, and then mirror polished. The surface is smooth, without cracks.2.Corrosion resistance: Surface chrome plated(10um-20um)3. Durable resistance: Adapting C45 high quality steel, high frequency hardness degree HRC60 ~ 644.High Accuracy : G6;Diameter tolerance:-0.005mm-.0.27mm; Length tolerance:+/-0.5mm(1M-3M);+/-1mm(3M-6M)5. High Fitness: Chamfer on both ends, easier to install linear bearings and won't hurt fingers when installing it.Model Number WCS SFC Series Solid shaft(Linear rod;Steel bar;Optical axis)Diameter of Linear Shaft Metric Diameter : 3mm,4mm,5mm,6mm,8mm,10mm,12mm,16mm, 20mm, 25mm, 30mm, 35mm,40mm, 50mm,60mm,80mm,100mmInch Diameter : 6.35mm,9.525mm,12.7mm,15.875,19.05,25.4mm,31.75mm,38.1mmMaterial Steel 45#;GCR15;Hardness HRC:58-62Hardened Layer Thickness 0.8-3.00mmPrecision G6Roughness Within1.5μmRoundness Within 3.0μm(Rmax)Straightness Not excess 1.5μm of 100mm (Rmax)Thickness of Chrome Plated 10-20μm,15μm on averageService  Specisl requirement onmachining,such as threading,coaxial holes drilled and tapped,radial holes drilled and tapped,reduced shaft diameter etc;We could supply OEM to our customers.Application 3d printer machine,Machine centers,Machine tools,Precision machining machines,Heavy cutting machines,Punching machines,Marble cutting machines,Automatic equipments,Grinding machines,High speed transfer equipments,Injection molding machines,Measuring equipments
