Precision Ground Spiral Bevel Gear with ISO 4-6 Grade Accuracy and HRC 58-62 Hardness for 90° Intersecting Shaft Applications

Precision Ground Orthogonal Gears and Long Integral Shaft for Industrial Drives

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.
