Precision ISO 4-6 Grade Spiral Bevel Gear with Extra-Long Integral Shaft and HRC 58-62 Hardness

3M Modulus Bevel Gear and Extra-Long Shaft | ISO 17485 Gear Set

This precision-ground orthogonal gear set with an extra-long integral shaft is engineered for high-performance industrial drive systems that require exceptional accuracy, stability, and durability. Manufactured with advanced grinding technology and produced under ISO 17485:2006-6 standards, the gear set delivers superior meshing quality, reduced noise, and high transmission efficiency—making it suitable for demanding machinery applications.

This gear assembly consists of a spiral bevel gear pair (Z = 44:11, Modulus 3M) combined with a one-piece extended shaft. The integrated design eliminates joint weaknesses and ensures excellent coaxiality, making the product ideal for long-distance torque transmission and high-speed operation.

The ground tooth surfaces significantly enhance precision and reduce backlash, while the optimized geometry enables smooth, quiet, and efficient power transfer even under heavy loads.

Key Features of 3M Modulus Bevel Gear and Extra-Long Shaft | ISO 17485 Gear Set

1. Small Backlash

Precision grinding combined with high-accuracy bearing positioning ensures minimal meshing clearance, resulting in smoother and more stable transmission.

2. Low Noise

The grinding process provides a more complete tooth contact pattern, significantly reducing meshing noise—ideal for noise-sensitive applications.

3. High Transmission Efficiency

With excellent consistency along the contact line, the transmission efficiency can exceed 96%.

4. Stable Long-Distance Power Transmission

The extra-long integral shaft ensures stable torque transfer, reduces vibration, and extends the service life of the machinery.

5. High Strength and Long Service Life

Premium materials combined with precision heat treatment deliver enhanced wear resistance and superior fatigue strength.
