Description

This CNC machined external spline shaft is manufactured from high-strength 20CrMnTi alloy steel, designed for reliable torque transmission and precision mechanical power transfer applications. The component is widely used in gearbox systems, industrial transmission equipment, and automated machinery requiring high wear resistance and dimensional accuracy.

Produced through advanced CNC turning combined with precision spline machining processes, the shaft ensures excellent concentricity, stable engagement performance, and long service life under dynamic loading conditions. The spline section is carburized and quenched to achieve high surface hardness while maintaining a tough core structure, providing superior resistance to wear, fatigue, and impact.

With strict quality control procedures including dimensional inspection and hardness testing, this spline shaft delivers consistent performance in demanding transmission environments. Custom dimensions, spline specifications, and surface treatments are available according to customer drawings or technical requirements.
