MHI HASEG Worm Gear Reducer SEUA Series

The MHI HASEG Worm Gear Reducer SEUA Series is a compact, two-stage horizontal-shaft worm gear reducer specifically engineered for high-reduction, light-duty applications. Combining MHI HASEG’s precision Niemann tooth profile with a space-saving double-worm design, the SEUA Series delivers smooth torque output, self-locking performance, and stable operation for small-scale machinery and automation systems.

Key Features

1. Two-Stage Compact Design
   
   The SEUA Series uses a dual-worm gear configuration to achieve high reduction ratios (up to 250:1) within a small housing, making it ideal for applications where high torque at low speed is needed in a limited space.
   
   

2. Niemann Tooth Profile for Smooth Operation
   
   The concave-convex Niemann tooth geometry increases tooth engagement area and improves oil film retention, providing smoother, quieter operation with reduced wear and longer gear life.
   
   

3. Self-Locking for Safety and Stability
   
   With low lead-angle worm gears in both stages, the SEUA Series offers strong self-locking properties, which prevent back-driving and help maintain precise positioning without the need for additional braking mechanisms.
   
   

4. Quiet and Vibration-Free Performance
   
   Optimized gear mesh design ensures low noise and minimal vibration, which is particularly important in laboratory, medical, or sensitive automation settings.
   
   

5. Efficient Lubrication & Easy Maintenance
   
   Splash lubrication with Klüber SYNTHESO HT or SYNTH GH6 ensures consistent performance. The reducer includes oil-level indicators, grease nipples for bearings, and accessible ports for oil filling and draining.
   
   

6. Compliant with JIS Standards
   
   All dimensions and tolerances are manufactured according to JIS B1301-1976, ensuring compatibility and ease of integration with other mechanical components.
