* Actual ratio combinations supplied by Factory may vary from above depending on application and manufacturing requirements. ** Size 860 is only available in GR and EL Series *** Sizes 870, 880 and 8100 are only available in GR Series Refer to page 211 for exact ratio of helical 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.

For input/ output shaft overhung load and thrust load ratings, refer to pages 646-648. EL Series sizes 842-860 have cast iron primary. Contact Factory for dimensions.
