* Actual ratio combinations supplied by Factory may vary from above depending on application and manufacturing requirements. Refer to page 141 for exact ratio of worm gear primary stage and worm gear secondary stage. At speeds above 1750 input RPM, gear reducers may become thermally limited. For continuous operation, limit input HP to 1750 RPM input ratings shown. Contact Factory with application requirements if higher speeds are required.
