Product RoleApplication Scenarios
Spline shafts are essential for systems that require both rotational power transmission and precise axial movement. Their multi-tooth design distributes load evenly, allowing compact construction without sacrificing strength.
Rectangular splines provide uniform stress distribution and excellent centering stability, whereas involute splines offer automatic alignment under load, minimizing backlash.
These shafts are ideal for high-speed gear shifts, robotic extension mechanisms, industrial gear drives, and other applications where rotation and axial sliding are required simultaneously.
