Features of Spline Gear Shaft
Multi-Tooth Engagement: With 4-20 teeth, it increases the contact area for power transfer by 3-5x compared to a single key, reducing slip to below 0.5%.
Precision Manufacturing: A combination of gear hobbing and grinding ensures minimal cumulative pitch error (≤0.02mm/100mm) and excellent concentricity (0.01-0.03mm).
Axial Movement Capability: Straight-sided splines allow the mating part to slide along the shaft's length while maintaining perfect rotational sync.
Robust Material Options: For heavy-duty use, we use 40CrNiMoA alloy steel, heat-treated to HRC58-62 for 4x the wear resistance.

Application Areas
Automotive: Drive axles, transmission output shafts, and 4x4 systems.
Heavy Machinery: Drivelines for excavators, bulldozers, and mining equipment.
Industrial Automation: Robotic arm joints and precision linear actuator drives.
Agricultural Equipment: Tractor PTO (Power Take-Off) shafts and combine harvester drives.
Q: Why is a spline drive shaft better than a keyed shaft?
A: A spline shaft distributes torque across multiple teeth instead of one single key. This eliminates shear failure, prevents slippage, and allows for axial movement, making it stronger and more versatile.
Q: What is the benefit of the "sliding" feature?
A: It allows for components to move in and out (like in a vehicle's drive axle as the suspension moves) while still transmitting full rotational power, which is impossible with a fixed keyed connection.
Q: How do I order a custom spline drive shaft?
A: Provide us with four key pieces of information: drive power, torque requirements, installation space, and mating part parameters. We'll handle the design and engineering.
