Precision Bevel Gear with Extra-Long Integral Shaft for CNC and Robotics Featuring ISO 4-6 Grade Accuracy and HRC 58-62 Hardness

Bevel Gears with Extra-Long Shaft for CNC, Robotics & Automation Systems

The bevel gears (paired with extra-long integral shafts) are precision-engineered power transmission components, crafted via orthogonal grinding technology (to ISO 1745:2006-6 standards). This one-piece gear-shaft assembly combines the high-torque transfer of bevel gears with the extended reach of an integral shaft — ideal for tight-space, high-precision applications like CNC, robotics, and automation.

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.
