Linear Guide Rail Set, 20mm x 1200mm, 2 Rails 4 Blocks

Linear guide rail set provides smooth, accurate linear motion for CNC builds and automation, helping reduce stutter and vibration under load. This 1200 mm (47.2 in) kit pairs carbon steel shafts with a rigid aluminum base, plus sealed SC20 slide blocks with ball bearings for low-friction travel. Designed for repeatable positioning, it supports stable movement in router, mill, lathe, 3D printer, and laser engraver projects where alignment and reliability matter.

Built for demanding shop and workshop setups, this linear rails and bearings kit combines corrosion-resistant chrome-plated surfaces with a sturdy aluminum base to help maintain alignment over time. The pre-matched components make it easier to design a reliable motion system without sourcing parts separately—ideal for upgrades, repairs, or new machine builds. If your project needs stable, repeatable linear travel over a full 1200 mm span, grab yours today and keep your motion platform running smooth.
