This product is a chrome-plated, hardened linear shaft with a standard diameter of 8mm. It is available in two common steel grades: C45, a versatile medium carbon steel, and GCr15, a bearing steel known for its high and uniform hardness after heat treatment. Both materials are processed to achieve a hardened surface, which is then finished with a durable chrome plating. This combination results in a component that is highly to wear and corrosion, with a smooth surface ideal for use with linear ball bearings.
Supplied in a single piece, the shaft length can be selected to match specific project requirements within the 100-700mm range. Its consistent diameter and high straightness make it a reliable choice for constructing or repairing precision linear motion systems. This component is engineered to serve as the primary guiding element in applications where accuracy, rigidity, and long-term reliability are critical, such as in automated slides, CNC router gantries, 3D printer axes, and other industrial or DIY motion mechanisms.
