2025 Top 10 spline shaft Suppliers in China

Introduction to Spline Shaft

A spline shaft is a mechanical component that features ridges or teeth, known as splines, machined along its length. These splines engage with corresponding grooves in a mating component, such as a gear, hub, or coupling. The primary function of a spline shaft is to transmit torque and rotational motion between two parts while allowing for some degree of axial movement. This makes them an essential part in various industrial applications, including automotive, aerospace, machinery, and power transmission systems.
