Top 10 Spline Shaft Manufacturers in China 2025

Jul 31, 2025

Introduction to Spline Shaft

A spline shaft is a mechanical component with ridges or teeth, known as splines, machined onto its outer surface. These splines engage with corresponding grooves in a mating part, such as a gear, coupling, or hub, to transmit torque and rotational motion. Spline shafts offer several advantages over other types of shafts, including high torque transmission capacity, precise alignment, and the ability to accommodate axial movement. They are widely used in various industries, such as automotive, aerospace, machinery, and power transmission.
