Configuration
Double Reduction
The double-reduction drive places two worm stages in series to reach very high reduction ratios — up to 5,000:1 — while retaining the compact right-angle footprint of the family. Ideal where extreme output-speed reduction and high mechanical advantage are required from a single sealed unit.

Features & Benefits
Why the Double Reduction Drive
Two-stage reduction
Serial worm stages deliver ratios beyond 70:1 up to 5,000:1.
Hardened & ground worms
Both stages use ground alloy-steel worms for long life.
Sealed cast housing
Single rugged housing protects both stages from harsh environments.
Built in the USA
Machined, assembled and supported in Cleveland, OH.
