Precision Versatile SAF37 Gear Motor

S-series helical gear - turbine reducer inside several helical gear and worm organically combined together, through the external motor and other equipment to provide power, the interaction between gear and worm or the use of external force, so that the reducer is in a state of working balance.
Although this reducer is also a helical gear reducer, it takes the form of a turbo worm. The S-Series reducer has a permissible torque of 90 to 4000 (N·m), and a power range of 0.12 to 22KW.

Product Overview


The S Series Gear Motor (models SAF37, SAF47, SAF57, SAF67, SAF77, SAF87, SAF97) is an innovative helical gear worm reducer that integrates helical gears and a worm drive into a single, high-performance unit. Designed to meet international standards, this gear motor features a turbo worm structure, combining the torque advantages of worms with the efficiency of helical gears. With a power range of 0.12KW to 22KW, output speed of 425r/min, and excellent adaptability, it excels in applications requiring frequent starts, precise transmission, and reliable operation in harsh environments. The S Series stands out for its compact design, heat dissipation capabilities, and versatile mounting options, making it a top choice for light to medium industrial equipment.


Features & Benefits


Advanced Gear-Worm Combination

Integrates helical gear and worm drive for enhanced torque output and transmission efficiency, outperforming traditional single-drive reducers.

Complete specifications and wide speed range (425r/min) offer strong versatility, matching diverse application requirements.

High transmission accuracy ensures consistent performance for equipment requiring precise motion control.


Efficient Heat Dissipation & Vibration Absorption

Concave-convex body surface design enhances heat dissipation, reducing temperature rise during prolonged operation and extending component life.

Strong vibration absorption capabilities minimize operational instability, protecting connected equipment from damage.

Low temperature rise and low noise operation make it suitable for noise-sensitive environments like workshops and laboratories.


Flexible Installation & Environmental Adaptability

Supports 90-degree transmission operation and multiple mounting types (flange-mounted, foot-mounted, hollow shaft-mounted), fitting various equipment configurations.

Excellent sealing performance prevents dust, moisture, and debris ingress, adapting to harsh working environments (e.g., dusty or humid conditions).

Compatible with various motor types, forming mechatronic integration for simplified equipment design.


Durable & Wear-Resistant Construction

Key components (gears, worm) are made of high wear-resistant materials and undergo special heat treatment, ensuring long service life.

Compact size with large bearing capacity maximizes space utilization, ideal for equipment with limited installation space.

Safe and reliable performance with a long service life, reducing replacement and maintenance costs.
