Linear Guide Rail Set, 16mm x 1000mm, 2 Rails 4 Blocks

Linear guide rail set delivers smooth, accurate linear motion for CNC builds and automation projects, reducing stutter and play for cleaner cuts and repeatable positioning. This kit pairs 16 mm chrome-plated carbon steel shafts with sealed SC16 slide blocks and rigid rail supports to handle high loads while keeping movement low-friction and low-noise. Built for DIY CNC routers, 3D printers, laser engravers, and machine sleds where alignment, stability, and long travel matter.

• Includes 2× 1000 mm (39.4 in) SFC16 rails, 4× SC16 slide blocks, and 4× rail supports for a complete linear motion setup


• Delivers smooth travel with built-in ball bearings and sealed aluminum blocks for low friction, low noise sliding


• Improves accuracy with precision shaft straightness and consistent motion repeatability for CNC, milling, and engraving


• Handles loads up to 774 N dynamic and 1180 N static per block for high-load automation equipment


• Speeds installation with aligned mounting holes and a rigid aluminum base for secure fastening and easy connection

Upgrade your motion system with a linear rail and bearing kit designed for long-travel stability and dependable performance under pressure. The corrosion-resistant, chrome-plated shaft surface helps reduce rust in workshop environments, while the matched rail/slide block fit supports consistent movement across the full 1000 mm stroke. Ideal for router and lathe sleds, CNC machines, trainer rocker plates, and custom automated rigs. Grab yours today and start building a smoother, more precise machine.
