Uimoso Linear Rail Kit HGR20 2Pcs 1000 mm (39.4 in) Guide Rails with 4 Blocks

About this item

This Uimoso HGR20 kit gives you 2 linear rails (1000 mm / 39.4 in each) and 4 HGH20CA ball-bearing slide blocks, ready for CNC machines, mills, grinders, and similar builds. The rails are medium-carbon steel hardened to HRC58-62 with a chrome-plated, corrosion-resistant surface, while the blocks are alloy steel for durable, quiet motion. Tight tolerances (0.05 mm/1000 mm straightness, 0.1-0.22 μm finish) keep travel accurate and repeatable. Comes complete with 34 end caps and 4 rail clamps for a straightforward installation.
