S Series Worm Gear Units – Key Features

Smooth & Quiet Operation
Unlike conventional hypoid or helical gearing, the sliding contact design enables exceptionally smooth transmission with reduced vibration and noise.

Self-Locking Capability
The output shaft is non-reversible, providing inherent holding capability for applications requiring position stability and safety.

Compact Right-Angle Design
Orthogonal shaft configuration allows efficient installation in confined spaces while maintaining high torque transmission.

Wide Reduction Ratio Range
Single-stage reduction ratios from 10:1 to 60:1 deliver reliable speed reduction without complex multi-stage gearing.

Flexible Shaft Arrangements
Available in single-shaft and double-shaft configurations to suit varied input and output requirements.

High Torque Capacity
Torque range: 47 – 56,600 N·m, suitable for demanding industrial duties.

Extensive Model Range
17 frame sizes covering applications from light machinery to heavy industrial drives.

Available Types
B / BP / W / WP / K configurations for versatile installation layouts.

The SM Series Worm Gear Units are compact, high-performance speed reducers designed for smooth, quiet, and reliable power transmission. Built for durability and efficiency, they are ideal for applications requiring high torque output at low speeds, especially where space is limited.

Engineered with precision-cut worm and wheel geometry, the SM Series provides excellent load-carrying capability, stable operation, and inherent self-locking characteristics for added safety in lifting or holding applications.

Key Highlights:

• Compact design for space-saving installations

• High torque output with smooth, low-noise performance

• Reliable self-locking feature for secure positioning

• Robust construction for long service life

• Suitable for conveyors, mixers, machinery drives, and industrial automation
