This product is a high-precision chrome-plated linear shaft made from 45# carbon steel. It undergoes a process of hardening, precision grinding, and subsequent hard chrome plating. The chrome layer not only significantly enhances surface hardness and wear resistance but also provides excellent corrosion protection. The shaft is manufactured to tight geometric tolerances, including exceptional straightness and roundness, which are critical for minimizing runout and ensuring consistent, low-friction performance in dynamic applications.
Supplied as a single piece, it serves as a key component in constructing reliable linear motion systems. Its primary functions include acting as a piston rod within pneumatic or hydraulic cylinders (where the chrome plating seals effectively against seals) and serving as a guide shaft or optical axis in various automation equipment, machine tools, and precision instruments. The availability of a wide range of diameters and lengths allows for selection based on specific load, speed, and space constraints.
