Features of Involute Splined Shafts
Optimized Tooth Profile: The involute shape reduces stress concentration by over 40% compared to rectangular splines, significantly enhancing fatigue life.
High-Speed Capability: Precision balanced to G0.4 grade for smooth operation at speeds exceeding 3000 RPM, with minimal centrifugal force error.
Extensive Size Range: Available in modules from 0.5mm to 20mm, shaft diameters from 8mm to 600mm, and pressure angles of 20°, 30°, or 15°.
Wear-Resistant Coatings: Options like tungsten carbide spraying increase surface hardness to HV1200, improving wear resistance by 5x in abrasive environments.

Product Advantages
Higher Torque Capacity:
Carry 35% more load than similar-sized rectangular splines, handling up to 2000 N·m of peak torque reliably.
Prototype-Friendly Service:
We support one-off orders, allowing developers to access custom solutions without large inventory commitments.
Smoother High-Speed Operation:
Advanced balancing prevents vibration, protects adjacent bearings, and enables quiet running (≤60 dB).
Superior Durability:
The even stress distribution and optional hardened surfaces drastically reduce wear and the risk of tooth failure.

Q: What is the main advantage of an involute spline over a rectangular one?
A: The primary advantage is much better load distribution. The involute shape reduces stress concentration, allowing the shaft to handle higher torque and last longer under cyclic loading.
Q: Can these shafts be used in high-speed applications?
A: Absolutely. They are dynamically balanced to high-precision standards (G0.4), making them suitable for stable operation at very high RPMs, such as in centrifuges or turbochargers.
Q: Do you offer custom sizes for research projects?
A: Yes, we cater to R&D needs. You can order a single piece or a small batch with a minimal price premium, perfect for prototyping and testing.
