This product is a high-precision, hardened and chrome-plated linear shaft with a fixed diameter of 15mm, engineered for demanding linear motion applications. Constructed from GCr15 bearing steel\u2014a material renowned for its high hardness, wear resistance, and dimensional stability after heat treatment\u2014this shaft undergoes thorough hardening followed by a precise chrome plating process. This results in a component with a very hard surface (suitable for high HRC values), excellent corrosion resistance, and an ultra-smooth finish (Ra 0.2).
The combination of premium material and advanced finishing makes it ideal for use as the guiding rail in systems requiring high rigidity, minimal deflection, and long-term accuracy. It is commonly paired with linear ball bearings or bushings. Typical applications include high-precision stages in automated machinery, critical sliding components in industrial robots, precision measurement equipment, and other scenarios where reliable, low-friction linear guidance is paramount.
