S Series Helical–Worm Gear Reducer integrates a worm gear/worm pair with a precision helical gear stage, forming a highly efficient two-stage transmission where the input and output shafts intersect spatially. The gears and worm are carburized and quenched to a hardness of HRC 58–62, with a hardened layer depth of 0.2–2 mm for excellent wear resistance and long service life.
The worm wheel is cast from bronze using a centrifugal casting process to achieve superior strength and uniformity.

Featuring compact construction, stable torque output, and multi-installation flexibility, the S Series is widely used across demanding industrial sectors such as petroleum, metallurgy, mining, lifting, transportation, cement, construction, chemical processing, textiles, dyeing, pharmaceuticals, food processing, and environmental engineering.

Highlights

• High Reduction Ratios
  Two-stage reduction (helical gear + worm gear) delivers smooth transmission with large ratio availability.
• Innovative Structure
  The combination of a worm gear/worm set and a helical gear creates a compact reducer with non-parallel, non-intersecting input and output shafts.
• High Efficiency & Lightweight Design
  Optimized tooth geometry, modular configuration, compact housing, and reduced weight ensure higher efficiency and appealing industrial aesthetics.
• Low Noise & Low Vibration
  Fine ratio grading and precision-machined gears significantly reduce vibration and operational noise.
