This product is a heavy-duty, chrome-plated hardened linear shaft available in a comprehensive range of diameters and standard lengths. Engineered for industrial linear motion systems, it is offered in two material grades: GCr15 bearing steel, optimized for maximum wear resistance and fatigue strength, and C45 medium carbon steel, which provides an excellent balance of strength, toughness, and machinability. Both materials are heat-treated to achieve a uniform high hardness (HRC58-60) throughout, ensuring durability under repetitive loads.
Following heat treatment, each shaft is precision-ground to precise dimensional tolerances and finished with a layer of hard chrome plating. This combination results in a component with exceptional surface hardness, superior corrosion resistance compared to bare steel, and a very low coefficient of friction. The extensive selection of sizes allows for direct integration into a wide array of machinery designs without requiring secondary machining of the shaft itself. These shafts are fundamental components in building or refurbishing the linear motion systems of large-format CNC routers, laser cutting beds, automated material handling equipment, industrial printers, and other precision machinery where reliable, long-lasting linear guidance is critical.
