MHI HASEG Worm Gear Reducer SCOA Series

The MHI HASEG Worm Gear Reducer SCOA Series is a single-stage vertical shaft type reducer designed for compact, high-efficiency power transmission in space-constrained or vertically oriented applications. With advanced Niemann tooth profile technology, high-precision machining, and robust construction, the SCOA Series delivers smooth, quiet, and dependable performance in a wide range of industrial environments.

Key Features

1. Vertical Shaft Design for Space-Saving Layouts
   
   The SCOA Series features a vertical shaft configuration, making it ideal for equipment where a compact footprint and top-down or bottom-up power transmission are needed—such as mixers, agitators, and hoists.
   
   

2. Advanced Niemann Tooth Profile
   
   The special concave-convex tooth design improves contact surface area, reduces stress concentration, enhances oil film retention, and contributes to high efficiency and low wear under heavy loads.
   
   

3. High Load Capacity and Long Life
   
   Constructed with alloy steel worm shafts and high-strength bronze worm wheels, the SCOA Series ensures reliable performance, extended service life, and excellent resistance to shock and radial/axial loads.
   
   

4. Quiet and Stable Operation
   
   Precision gear finishing and optimal tooth geometry minimize noise and vibration, supporting smoother machinery operation, especially in production environments sensitive to sound and vibration.
   
   

5. Self-Locking Capability for Safety
   
   When using low lead angles, the SCOA Series prevents reverse motion, providing built-in mechanical holding power in vertical applications such as lifting mechanisms or conveyors.
   
   

6. Simple Maintenance
   
   Splash lubrication (using Klüber SYNTHESO HT or SYNTH GH6) ensures continuous gear protection. External grease nipples and oil-level indicators simplify routine maintenance.
