Specification Brand : Mssoomm BulletPoint1 : 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 BulletPoint2 : 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 BulletPoint3 : Adapting C45 high quality carbon steel, high frequency quenching, surface chromium plating. Using mirror polishing technology, more durable and corrosion-resistant. BulletPoint4 : Humanization Design: Chamfer on both ends, easier to install linear bearings and won't hurt fingers when installing it BulletPoint5 : 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 ExternallyAssignedProductIdentifier1 : 0679815064745 ExternallyAssignedProductIdentifier2 : 679815064745 ItemName : Mssoomm Linear Motion Shaft Rod Guide D 18mm x L 12.6 inch / 320mm 2Pcs, Hollow Rod D 18mm Inner Hole 11mm Smooth Steel Case Hardened Chrome Plated for 3D Printer, DIY, CNC - h7 Tolerance ItemPackageDimensions_Height : 149.86 centimeters ItemPackageDimensions_Length : 6.35 centimeters ItemPackageDimensions_Width : 6.35 centimeters ItemTypeKeyword : linear-motion-guides Manufacturer : Mssoomm Material : Carbon Steel ModelNumber : MS-2-KXGZ-D18-ID11-L320 NumberOfItems : 1 PartNumber : MS-2-KXGZ-D18-ID11-L320 ProductDescription : Specifications: Brand: Mssoomm Material: High Quality Carbon Steel (C45#) Hardness: 58-60 HRC Surface Hard-thickness: 0.8 – 2.5mm Surface Roughness: 0.8S – 1.6S Straightness: Below 5μm/100mm Surface Chrome Thickness: 15um-20um Surface Finish Quality: Ra 0.1 - 0.35 Color: Silver This items includ: 2pcs 18mm x 12.6 inch / 320mm hollow linear rail shaft rod with Inner Hole 11mm Lead Time: If this item is not FBA, the lead time is 7-10 Business Days except for for Chinese National Day holiday and Spring Festival If you can accept the lead time as 45 natural days, we can ship the items to you by sea, the price will be lower, please message us.
