Helical Worm Speed Reducer

For high-duty packaging lines, textile machinery, and automated assembly equipment, standard drive units often run hot and wear out quickly, leading to costly downtime. Our SHF series helical worm speed reducer is designed to solve these high-duty issues by integrating a pre-stage helical gear set that reduces the input speed before it reaches the worm gear stage. This design significantly lowers the sliding friction and heat generation of the worm set, increasing overall efficiency and extending the service life of the gears. In our Hangzhou plant, the helical and worm gears are ground on Swiss Reishauer grinders to meet accuracy grade 5-6 (GB/T10095), and the shafts are fitted with high-precision FKM oil seals. This ensures that every helical worm speed reducer delivers smooth, cool, and leak-free power transmission, keeping your clients' production lines running continuously with minimal maintenance.

We are committed to helping our global distributors succeed by providing factory-direct communication, reliable production schedules, and rigorous quality assurance. Every helical worm speed reducer we manufacture undergoes a thorough 100% manual quality inspection to verify that all gear tolerances, seal pressures, and operating noise levels meet our high standards. Located in Hangzhou's Qiantang District, we are positioned close to major shipping networks, allowing us to offer fast and reliable delivery options. By distributing our highly durable, cool-running helical-worm speed reducers, you can provide your local manufacturing clients with a robust, energy-efficient solution that reduces wear and protects their equipment, making your business the premier choice for power transmission components.

We offer customization for non-standard hollow shaft bores, special shrink disc configurations, and custom mounting torque arms with an MOQ of 50 sets. We require full payment before we arrange the custom manufacturing process. Technical design files must be sent in PDF format on A4 paper with all dimensions marked in millimeters (mm).

We perform a meticulous 100% manual inspection on every reducer, focusing on gear backlash, thermal performance, and dynamic oil sealing. The gearboxes are packed in sturdy, export-standard wooden cases with protective foam inserts to safeguard the precision hollow output shafts from scratches during transit. Our delivery cycle is strictly maintained within 2 months.
