Linear Guide Rail Kit 1000mm, 2 Rails with Ballscrew

HGR20 linear guide rail kit delivers smooth, precise linear motion for DIY CNC routers, lathes, and mills, helping reduce play and vibration under load. This set combines two 1000 mm square rails with four sliding blocks plus an RM1605 ballscrew and support hardware for stable travel and consistent positioning. Built from carbon steel and GCr15 bearing steel with a plated surface, it’s designed for low-friction movement, low noise, and durable performance in automation and precision equipment builds.

• Includes 2x HGR20-1000 rails, 4 blocks, 1x RM1605-1000 ballscrew, 1x ball nut, BF12/BK12 supports, 1x plum coupling


• Delivers low-friction, high-precision linear travel for CNC, automation, and measuring equipment


• Supports rigid, stable motion with high hardness steel components for reduced wear


• Simplifies mounting with pre-drilled rail holes and an end-machined ballscrew for alignment


• Runs smoothly with low noise to improve cut quality and repeatability on DIY machines

Upgrade your motion system with a matched rail-and-ballscrew assembly built for accurate, repeatable travel. The square linear guide design helps keep your carriage aligned while the RM1605 ballscrew supports controlled feed movement—ideal for retrofits, new CNC builds, and precision sliding stages. Use it to replace worn rails, tighten tolerances, or increase stability on longer travel axes. Grab yours today and get your machine moving cleaner, straighter, and more consistently.
