S Series Helical Worm Gear Reducer

Product Overview

The S series helical worm gear reducer is a high-efficiency transmission solution designed by combining a helical gear stage with a worm gear stage into one compact, powerful gearbox. Unlike traditional single-stage worm gear reducers that rely solely on sliding friction, the S Series adopts a helical primary stage to improve meshing efficiency and torque capability. This hybrid structure allows the reducer to achieve higher output torque, greater efficiency, lower temperature rise, and smoother operation, making it suitable for a wide range of industrial automation applications.

With a modular structure, compact housing, flexible mounting configurations, and excellent heat dissipation, the S series helical worm gear reducer delivers reliable and stable performance under continuous operation. The unit is engineered using high-quality alloy steel, precision-machined gears, advanced heat treatment technology, and durable sealing components to ensure longevity even in harsh industrial environments.

To further enhance reliability and corrosion resistance, the S series helical worm gear reducer features reinforced sealing, anti-corrosion surface coating, and a high-rigidity housing. Because of its low noise, good sealing performance, and high versatility, it has become a widely used reducer type in mechanical equipment, especially in conveyors, packaging lines, material handling equipment, and machinery requiring consistent low-speed, high-torque output.

The S series helical worm gear reducer is also compatible with global servo motors and induction motors from leading brands such as Siemens (https://www.siemens.com), Yaskawa (https://www.yaskawa.com), Mitsubishi Electric (https://www.mitsubishielectric.com), and Delta Electronics (https://www.deltaww.com), making it convenient for OEMs and end users seeking flexible drive integration.

Key Features

  • Helical + Worm Gear Combined Transmission
    By integrating a helical gear as the first reduction stage and a worm gear as the output stage, the S Series significantly improves efficiency compared to traditional worm gear reducers. This structure provides:
    Higher torque output;
    Improved efficiency;
    Wider reduction ratio range;
    Smoother meshing and quieter operation
  • Compact Design & Flexible Mounting
    The S series helical worm gear reducer is engineered with a small footprint, lightweight structure, and multiple mounting options (foot-mounted, flange-mounted, shaft-mounted). This makes it easy to integrate into machines with limited installation space.
  • Excellent Heat Dissipation & Low Temperature Rise
    The combination of helical-worm transmission and high thermal conductivity housing ensures:
    Low operating temperature;
    Reduced energy loss;
    Longer lubricant life
  • High Transmission Precision & Self-Locking Capability
    The worm gear design provides natural self-locking under certain conditions, enhancing safety in applications with vertical loads or frequent start/stop cycles.
  • Strong Sealing & Environmental Adaptability
    High-grade seals and optimized housing prevent lubricant leakage and protect internal components from dust, moisture, and corrosive environments.
  • Low Noise & Smooth Operation
    Helical gear input reduces vibration while the worm gear ensures smooth, silent output—ideal for equipment requiring stable, quiet motion.
  • Long Service Life
    Precision grinding, optimized gear geometry, and high-strength materials ensure excellent durability and long-term performance.
