상품 특징

• Precision Diameter Tolerance : Each 8mm rod is ground to a tight tolerance of -0.005 to -0.03mm (actual 7.995-7.97mm), ensuring a smooth fit with linear bearings and shaft supports for 3D printers, CNC machines, and automation projects
• Hard Chrome Plated Surface : Made from carbon steel with 10-20um hard chromium plating. Surface hardness reaches 57-62 HRC – resists wear, and keeps rods straight and smooth for consistent linear motion
• Clean & Consistent Length : Length tolerance of ±0.5mm (150mm nominal). Ends are cleanly cut with a slight chamfer, making it easy to insert into bearings or shaft collars without sharp edges that hurt your fingers
• Straight & True for Motion : Engineered to be dead straight with a mirror-like finish. No bends, no wobble – ideal for upgrading 3D printer axes, CNC routers, engraving machines, or replacing worn shafts on band saws and other shop equipment
• 2-Pack Ready to Use : You get two 8mm x 150mm linear motion rods. Enough for dual axis upgrades, spool holders, or small DIY motion systems. Affordable and reliable for makers and repair projects
