Rossi
SR Series - Coaxial Servo Gear Reducers
The Rossi SR Series coaxial servo gear reducers are precision-engineered inline drives designed to integrate directly with high-performance servo motors for the most demanding motion control applications. Combining a compact coaxial architecture with high torque capacity, low backlash, and exceptionally quiet operation, these gear reducers ensure precise, repeatable positioning and efficient power transmission. The direct servo motor coupling—achieved via a slotted bushing and hub clamp system—eliminates the need for external couplings or adapters, simplifying drivetrain design and reducing overall installed length. Ideal for robotics, pick-and-place systems, CNC machine tools, and high-speed packaging machinery, the SR coaxial variant delivers the accuracy and reliability that automation engineers and machine builders demand for high-cycle, precision-motion processes.

Why Coaxial Servo Gear Reducers Are the Standard for Robotic and CNC Drives
Inline coaxial gearboxes provide a natural axis of symmetry between motor and driven shaft, making them the default choice for robotic arm joints and CNC ball-screw drives where alignment and compactness are critical. The Rossi SR Series elevates this architecture with best-in-class backlash control and torsional stiffness, ensuring that even the most dynamic motion profiles are executed without overshoot or oscillation. For system integrators, the result is faster commissioning, improved machine accuracy, and reduced long-term maintenance due to robust, well-lubricated internal construction.
