* Caution - The motor power may exceed the gear unit’s mechanical torque capacity. Limits Based on 1750rpm input speed.
Ê Non-footed units only.
The mechanical power limit of the solid input shaft type “W” may limit the reducer rating.
All ratings are mechanical. See page 14 for thermal considerations.
