Linear Motion Rods, 25mm x 1000mm, 2-Pack, Steel

Linear motion rods deliver smooth, accurate travel for CNC and automation builds, reducing vibration and binding during repeated cycles. This 2-piece shaft kit uses hardened high-carbon steel and precision grinding to support stable motion under load. Designed for broad compatibility with linear bearings and rail systems, it’s suited to milling, drilling, grinding, and cutting machines where straightness and surface finish directly impact performance.

• Includes 2 precision shafts for building or replacing linear rail guide setups


• Delivers smooth, quiet travel with a ground 0.1–0.22 μm surface finish


• Resists bending under load with HRC58–62 hardened high-carbon steel


• Protects against rust with ≥10 μm electroplated surface for damp workshops


• Fits CNC, lathes, robotic arms, laser welding, wire drawing, and automation rigs

When your machine needs repeatable positioning, straightness and hardness matter. These linear guide shafts are manufactured with a multi-step grinding process to help maintain consistent motion over long runs, with a deformation-resistant design that supports demanding shop use. Ideal for upgrades, repairs, or new builds where clean travel and stable alignment are priorities. Grab yours today and get your motion system running smoother and more reliably.
