HUAKE
The Huake S Series Helical-Worm Gear Motor (Model: SAF47) delivers a compact right-angle drive solution combining helical gear precision and worm gear torque amplification. Engineered by Huake Transmission, this model provides high-efficiency speed reduction in a lightweight, maintenance-free design.
Featuring a 47 mm center distance and foot-mounted with flange-coupled motor design, the SAF47 unit offers high torque density and smooth, quiet transmission. It is ideal for automated conveyors, packaging machinery, lifting equipment, and light industrial drives, where reliability and space optimization are critical.
| Parameter | Description |
|---|---|
| Model | S Series Gear Motor – SAF47 |
| Transmission Type | Helical–worm compound, right-angle drive |
| Housing Material | Aluminum alloy (standard) / Cast iron (optional) |
| Gear Ratio Range | i = 5:1 – 100:1 (extendable to 200:1) |
| Center Distance | 47 mm |
| Rated Power Range | 0.09 kW – 2.2 kW |
| Output Torque | Up to 200 N·m (ratio-dependent) |
| Output Speed | 10 – 200 rpm |
| Efficiency | 85% – 92% |
| Mounting Type | Foot-mounted + Flange-connected motor (A+F configuration) |
| Output Shaft Options | Hollow or solid shaft |
| Noise Level | ≤ 55 dB |
| Lubrication | Fully sealed synthetic gear oil (maintenance-free) |
| Protection Grade | IP55 standard, optional IP65 |
| Working Temperature | –15 °C to +50 °C |
Precision-ground helical gears paired with a bronze worm wheel deliver smooth torque output, high shock resistance, and superior energy efficiency compared to conventional worm gearboxes.
The 90° output layout allows flexible installation in confined spaces. Perfect for automation systems, lifting platforms, and packaging lines requiring compact but powerful drive units.
The optimized tooth geometry and precision-machined bearing seats ensure low vibration (≤55 dB), achieving up to 92% transmission efficiency and long service life.
The die-cast aluminum housing ensures rigidity with lightweight construction. Supports horizontal, vertical, and wall-mounted configurations with standard IEC motor interface (B5/B14).
Factory-filled synthetic lubricant and sealed housing allow continuous 24-hour operation without periodic servicing—ideal for demanding industrial environments.
| Advantage | Description |
|---|---|
| High Efficiency | 15–25% higher than traditional worm reducers, reducing power loss. |
| Durability | Alloy steel gears and bronze worm wheel provide wear resistance under heavy load. |
| Easy Integration | Modular connection with IEC motors and servo drives. |
| Lightweight Design | Aluminum body cuts weight by 35% vs. cast iron models. |
| Self-Locking Capability | Worm geometry prevents reverse motion, ideal for lifts or hoists. |
Automated Conveyor Systems – Smooth speed reduction and high torque for stable conveying.
Packaging & Filling Machines – Clean, quiet operation in compact machinery.
Lifting & Door Systems – Self-locking drive ensures safe load positioning.
Textile & Printing Lines – Continuous operation with low noise and low maintenance.
Robotics & Motion Control – High torque density for compact automation modules.
Huake S Series Gear Motors are widely used across manufacturing, logistics, and automation sectors where efficient, compact, and durable drive solutions are essential.
Q1. What does “SAF47” mean?
“S” stands for S Series (Helical-Worm), “A” indicates foot-mounted housing, “F” refers to flange motor coupling, and “47” is the frame size (47 mm center distance).
Q2. What advantages does the S Series offer over worm gearboxes?
Higher efficiency, quieter operation, longer service life, and compact structure with high torque density.
Q3. Can it be used vertically?
Yes. The SAF47 supports all installation orientations—horizontal, vertical, or wall-mounted—with proper lubrication levels.
Q4. Is it compatible with IEC motors?
Yes, compatible with IEC B5/B14 flange motors and can be customized for servo or variable-speed applications.
Q5. Does it require maintenance?
No. It is factory-sealed and lubricated, designed for lifetime operation without routine servicing.
