Worm Gear Sets
Our precision worm wheels, worms and worm gear sets are available in modules 0.5 to 4 and in various configurations, ensuring reliable power transmission through their steel and bronze material combination. These components are ideally suited for general mechanical engineering and for achieving high reduction ratios in compact gearbox solutions.
- 1–8 thread starts
- High reduction ratios achievable
- Self-locking depending on reduction ratio
- Lower efficiency compared to spur or bevel gears
