MHI HASEG Worm Gear Reducer SEOH Series

The MHI HASEG Worm Gear Reducer SEOH Series is a high-performance, two-stage horizontal-shaft reducer designed for demanding applications requiring high reduction ratios, superior durability, and consistent torque delivery. With its advanced Niemann tooth profile and precision-crafted gearing, the SEOH Series offers compact power transmission with excellent efficiency, reliability, and self-locking capability.

Key Features

1. Two-Stage Horizontal Shaft Design
   
   The SEOH Series features dual worm gear stages in a horizontal configuration, allowing high reduction ratios (up to 250:1) within a compact footprint. Ideal for applications where horizontal layout is preferred and space is limited.
   
   

2. High Reduction Ratios with Niemann Tooth Profile
   
   MHI HASEG’s proprietary concave-convex Niemann tooth profile ensures superior surface contact, improved oil film retention, and uniform load distribution. This results in smooth operation, reduced wear, and increased transmission efficiency.
   
   

3. Robust Load Handling
   
   The SEOH Series is engineered with hardened alloy steel worm shafts and high-strength bronze worm wheels, delivering strong resistance to both radial and axial loads, and maintaining high performance under continuous operation.
   
   

4. Self-Locking Mechanism
   
   With low lead angles in both stages, the SEOH Series naturally resists back-driving, providing built-in safety and stability in lifting or braking-critical systems.
   
   

5. Reliable Lubrication & Maintenance
   
   Splash lubrication using Klüber “SYNTHESO HT” or “SYNTH GH6” ensures continuous gear protection. Separate oil chambers and level gauges for each stage support reliable long-term operation. Grease nipples allow for simple bearing maintenance without disassembly.
   
   

6. Precision Housing & Easy Installation
   
   The housing is machined to JIS B1301-1976 standards, ensuring proper shaft alignment and minimal backlash. Designed with installation-friendly mounting surfaces and accessible service points.
