Product Description

 

1. Product Overview

A spline shaft is a sophisticated mechanical transmission component ingeniously designed with longitudinal keyways on its surface. These keyways perfectly match with hub keyways, facilitating seamless torque transmission and synchronous rotation. Certain types are engineered to also support axial sliding (such as those found in gearbox gears), showcasing exceptional high load capacity, precision centering, and reliable guidance.
