Features of Hollow Spline Shaft
Significant Weight Reduction: The hollow core design reduces weight by 30-60% compared to a solid shaft of the same diameter, lowering inertia and energy consumption.
Integrated Cable Routing: The central bore serves as a protected passage for wiring, hoses, or sensors, keeping them organized and safe from external damage.
Dual-Function Design: Available with internal or external splines, allowing one shaft to connect multiple components, such as a motor and a generator, simultaneously.
Precision Cold Forming: For smaller modules (≤3mm), we use cold extrusion to create splines with 98% material fullness, increasing strength by 20%.

Q: What is the primary benefit of a hollow shaft?
A: The main benefit is a major reduction in weight without a proportional loss of strength, leading to lower energy consumption, faster system response, and reduced load on bearings.
Q: Can I run cables through the hollow shaft?
A: Absolutely. The central bore is designed precisely for this purpose, protecting electrical wires, hydraulic lines, or fiber optics from wear and tear in dynamic applications.
Q: Do you offer custom sizes for prototypes?
A: Yes, we specialize in low-volume and prototype orders. You can order a single custom Hollow Spline Shaft to test and validate your design.
