Distinguished by its simple design, it ensures reliable and quiet operation, making it ideal for noise-sensitive environments. The integration of a helical gear stage significantly boosts its efficiency compared to standard worm gear units. Offering versatile input configurations such as direct motor coupling or IEC flange mounts, and flexible output configurations including solid or hollow shafts, it caters to diverse installation needs. Available in multiple variants (Series S / SF / SA / SAF), this compact unit supports foot- or flange-mounting options, providing adaptable and dependable performance across various industrial settings.
Product Advantages
Enhanced Efficiency & Cost-Effectiveness
The S Series Helical Worm Gear Motor significantly boosts efficiency through its integrated helical gear stage, achieving up to 15% higher efficiency compared to standard worm gear units. This design reduces energy loss and operational costs, making it a highly cost-effective solution for continuous-duty applications. Its linear power transmission ensures smooth torque delivery, minimizing mechanical stress and contributing to long-term reliability in various industrial settings.
Quiet & Reliable Operation
Engineered for low-noise performance, the S Series operates at sound levels below 65 dB(A) in most configurations, thanks to its optimized helical-worm gear engagement and precision manufacturing. This makes it ideal for environments where noise reduction is critical, such as packaging lines or indoor production facilities. The simple design not only lowers initial costs but also enhances reliability, with many units delivering maintenance-free operation for over 20,000 hours under normal conditions.
Flexible Mounting & Configuration
Offering versatile input configurations—including direct motor coupled, IEC B5/B14 motor flange, and solid input shaft options—the S Series adapts seamlessly to diverse machinery layouts. Similarly, multiple output configurations like solid output shaft, hollow output shaft, and flanged variants provide engineers with design flexibility. This adaptability is further extended through variants such as SA and SAF, which support specialized mounting and connection requirements.
Robust Hollow Shaft Connection Options
The series features durable hollow shaft designs with multiple connection methods, including keyed connection, shrink disk, and splined hollow shaft. These options ensure secure torque transmission even under high-load conditions, with some models supporting torque capacities up to 500 Nm. The availability of a Torque Arm variant adds stability in applications with significant radial or axial forces, enhancing overall system safety and longevity.
Simplified Maintenance & Long Service Life
Designed for minimal upkeep, the S Series incorporates wear-resistant gearing materials that provide a service life exceeding 10 years in typical applications. Its foot- or flange-mounted variants simplify installation and alignment, reducing downtime during maintenance. The gear unit’s sealed housing and high-quality lubricants further extend maintenance intervals, ensuring reliable performance in demanding environments such as material handling and automated assembly systems.

Product Uses
Light-Duty Conveying & Sorting Systems
The S series gear units are perfect for driving light-duty conveyors, sorters, and assembly line transfers. Their linear power transmission ensures exceptionally quiet operation, making them ideal for work environments with low noise requirements. The compact design and simple installation via B5 or B14 flange-mounted options allow for easy integration into space-constrained automation equipment.
Ventilation & Air Handling Equipment
This gear motor is well-suited for powering fans, blowers, and ventilation systems. The combination of helical and worm gearing provides smoother operation and higher efficiency compared to pure worm drives, leading to lower energy consumption. The availability of both solid or hollow output shaft configurations offers flexible coupling solutions to various fan impellers.
Basic Material Processing & Agitation
For simple mixing, stirring, or light agitation tasks in chemical, food, or industrial settings, the S Series offers a reliable and economical solution. Its simple design ensures cost-effectiveness for straightforward applications. The gear unit can be configured with a hollow output shaft with flange for direct mounting to an agitator shaft, simplifying mechanical design and installation.
Product Operate Guide
To ensure optimal performance and user experience with your S series helical-worm gear units, please follow these key steps. First, securely mount the gearbox using either the foot- or flange-mounted option, ensuring proper alignment to minimize vibration and noise. Second, select the appropriate input configuration, such as a direct motor coupling or IEC B5/B14 motor flange, and connect it to the power source. Finally, attach your load to the chosen output configuration—be it a solid output shaft or hollow output shaft—using the recommended connection method.
