This product is a pair of chrome-plated, hardened linear shafts designed for integration into precision linear motion assemblies. The chrome plating over a hardened steel substrate creates a durable, smooth, and corrosion-resistant surface essential for long service life and consistent performance when used with linear bearings (e.g., ball bushings). A key feature is the pre-drilled and tapped holes at both ends of each shaft. This design allows for straightforward and secure mounting to frames, brackets, or between end supports using standard metric screws, eliminating the need for additional shaft collars or complex fixtures in many applications.
The shafts are supplied as a matched set of two, which is typical for constructing a stable parallel guide system. Available in standard diameters and customizable lengths, they offer flexibility for various mechanical designs. These components are commonly employed in building or repairing the motion systems of DIY CNC routers, 3D printers, laser engravers, and other automated equipment where precise and reliable linear movement is required.
