Product RoleApplication Scenarios
In modern machinery, the spline shaft is indispensable for its ability to provide simultaneous torque transmission and precise positioning. Its multi-tooth geometry increases contact area and load capacity, enabling compact yet powerful designs.
Rectangular splines are well-suited for applications needing stable centering and stress uniformity, while involute splines automatically align under load, reducing wear and ensuring accurate power transfer.
The shaft is ideal for use in high-speed gear shifting, robotic extension arms, industrial gear drives, and other systems requiring both rotation and controlled sliding motion.
