The S Series Helical Gear-Worm Gear Reducer is a precision-engineered power transmission device designed for heavy-duty industrial applications. Featuring a direct-axis structure, its high-speed stage adopts involute helical gear transmission with gears processed through carburizing, quenching, and grinding technologies—ensuring exceptional durability and smooth operation. The output stage integrates worm gear transmission, combining the advantages of helical gears (high efficiency) and worm gears (large torque) to deliver a compact, reliable solution for diverse speed reduction needs.
Ideal for solving pain points like limited installation space, insufficient torque, and low transmission efficiency, this reducer boasts a wide power range, fine transmission ratio grading, and long service life. Whether for lifting equipment, mining machinery, or food processing lines, the S Series Helical Gear-Worm Gear Reducer provides consistent performance that meets ISO standards, making it a trusted choice for global industrial users.
The S Series Helical Gear-Worm Gear Reducer features a streamlined structure that minimizes installation space, making it perfect for equipment with tight layouts. Unlike bulkier alternatives, its compact size does not compromise torque output—allowing it to fit seamlessly into existing production lines without major modifications.
With an output torque range of 3.5N.m ~ 22500N.m, this high torque gear reducer excels in heavy-load scenarios, ensuring stable operation even for high-demand machinery like conveyors and metallurgical equipment. Its helical gear-worm combination achieves high transmission efficiency, reducing energy loss and lowering operational costs for businesses.
Compatible with input power from 0.12kw to 200kw, the S Series Helical Gear-Worm Gear Reducer adapts to diverse industrial needs—from small-scale light industry to large-scale mining operations. The transmission ratio ranges from 4.16 to 22323, and for ratios exceeding 200, it can be combined with R Series reducers, offering precise speed control for customized applications.
Each S Series Helical Gear-Worm Gear Reducer undergoes strict quality control, with gears processed via carburizing, quenching, and grinding to enhance wear resistance. Backed by ISO certification, it guarantees reliable performance and a long service life, reducing maintenance frequency and downtime for industrial facilities.

The S Series Helical Gear-Worm Gear Reducer is widely used across multiple sectors, thanks to its versatility and robust performance:
Lifting & Hoisting Equipment: Cranes, elevators, and hoists
Transportation Machinery: Belt conveyors, spiral unloaders, and impeller coal feeders
Mining & Metallurgy Industry: Ore processing equipment, smelting machinery
Petrochemical & Chemical Plants: Pipeline pumps, mixing equipment
Textile & Dyeing Machinery: Weaving machines, dyeing lines
Light Industry & Pharmaceutical Equipment: Packaging machines, pharmaceutical production lines
Food Processing Machinery: Food conveyors, mixing and blending equipment
Environmental Protection Machinery: Wastewater treatment pumps, dust collectors
Equipped with a 6mm diameter breather hole, the oil cup-type breather cap balances internal and external pressure, preventing clogging from coal dust or oil contamination. Refueling is done directly through the oil cup—no need to open the inspection cover, reducing leakage risks.
For half-shaft reducers: A spare oil seal is installed outside the end cover, enabling quick replacement without disassembling the reducer or coupling.
For full-shaft reducers: A split-type end cover and open-type oil seal simplify installation, reducing workload while enhancing sealing performance.
D05 silicone rubber sealant is applied to joint surfaces and end covers during overhauls, while emergency oil surface repair agents handle unexpected leaks at static sealing points. Strict assembly procedures ensure no oil seepage, even in harsh working environments.
Choose from four flexible installation options based on your equipment needs: foot mount, flange mount, hollow shaft, or flange hollow shaft. Ensure proper alignment to avoid excessive wear.
Install oil seals correctly (spring side inward) without damaging the lip edge or deforming the outer edge.
Clean joint surfaces thoroughly and apply sealant evenly.
Maintain oil levels within the dipstick mark—avoid overfilling.
Regularly wipe the shaft to remove coal dust or oil stains, especially after equipment shutdowns.
Each S Series Helical Gear-Worm Gear Reducer is manufactured under strict ISO standards, with quality guaranteed through rigorous testing. Our after-sales team provides comprehensive support, including technical consultation, maintenance guidance, and replacement parts supply. We stand behind the reliability of our products, ensuring minimal downtime for your operations.
For transmission ratios exceeding 200, combine the S Series Helical Gear-Worm Gear Reducer with R Series reducers to meet high-ratio requirements. This combination retains all the advantages of the S Series while expanding its application scope for specialized industrial needs.
The S Series Helical Gear-Worm Gear Reducer is ideal for lifting & hoisting, transportation, mining, petrochemical, textile, pharmaceutical, food processing, and environmental protection industries, adapting to diverse heavy-duty and precision transmission needs.
Yes, it can reach up to 22323 by combining the S Series Helical Gear-Worm Gear Reducer with R Series reducers, meeting high-ratio application requirements while retaining core advantages.
Four options are available—Foot Mount, Flange Mount, Hollow Shaft, and Flange Hollow Shaft—with selection based on your equipment structure; our technical team can offer personalized recommendations.
For static sealing points, use emergency repair agents; for dynamic points, check and replace oil seals as guided, and ensure the breather cap is unclogged and oil levels are proper.
Yes, it can be customized in input power, output torque, transmission ratio, and other aspects—contact our team to discuss your specific requirements for a tailored solution.
It comes with a standard 12–24 month warranty (region-dependent) covering manufacturing defects, with comprehensive after-sales technical support and replacement parts supply.
