Worm Gear:

- Bronze worm wheel
- No bearing
- Harder to install
- Heavier housing & limited mounting positions

- Bearing
- Grease lube (maintenance free!)
- No leak, triple lipped seals
- Easy to install
- Lightweight housing with universal mounting
- High efficiency hypoid gearing

Sumitomo's Hyponic drives use patented, all-steel hypoidal gear technology that leads the industry in high-efficiency and quiet operation.
All-steel hypoid gears transmit torque more efficiently, ensure long service life and deliver efficiencies of 80-85% across ratios from 30:1 to 1440:1!
