About Right Angle Reducer
Sango Automation is a professional precision custom gear manufacturer. Since our establishment in 2010, we have accumulated more than ten years of specialized gear manufacturing experience. We have successfully provided customized right angle reducer solutions for high-end robot arm manufacturers and automated production lines in Germany, Canada, and Japan. Our commitment to using high-grade materials and rigorous testing has earned us a reputation for reliability, evidenced by our high customer repurchase rate. Whether you require a standard right angle reducer or a specialized high-torque variant, our engineering team leverages a decade of expertise to ensure your project's success.
Products Features
Compact 90 Configuration
The right angle reducer features a perpendicular drive design that allows the motor to be mounted at a 90-degree angle to the output shaft. This significantly reduces the overall machine footprint, making it an ideal solution for automated equipment with limited installation space where inline gearboxes cannot fit.
High Precision & Low Backlash
Utilizing precision-ground spiral bevel or worm gears, the right angle reducer maintains a standard backlash as low as 3 arc-min (depending on the model). This mechanical precision ensures stable torque transmission and highly accurate repetitive positioning in multi-station indexing applications.
High-Rigidity Internal Bearings
Each reducer is equipped with heavy-duty internal bearings-often cross-roller or tapered roller types-designed to handle significant axial and radial loads simultaneously. This robust internal support prevents shaft deflection under high-torque conditions, ensuring long-term operational stability.
Universal Motor Interface
The right angle reducer is designed with a flexible flange system compatible with all major brands of servo and stepper motors. By using standardized dimensions and exchangeable shaft bushings, it allows for a quick "plug-and-play" installation without the need for additional mechanical modifications.
