LMI has selection options for several different sizes of shaft mounts, all of which share the nominal ratios of 9:1,15:1, and 25:1, with output speeds up to 200RPM and ratings up to 200HP. DIR shaft mount reducers are selected by input horsepower and the output speed they provide. AGMA load applications have been provided in our brochure to help you determine the correct size of shaft mount for your specific application.

Determine the AGMA Load Classification Number for your application from the tables. In mechanical drives, the presence of shock loads will usually reduce the life of the reducers. In order to provide optimum service in heavily loaded applications, it is necessary to use load classes to adjust the reducer ratings for the stresses created by different types of loads. The AGMA Load Classes provide for a momentary or starting load of 2.0 times for Class I, 2.8 for Class II, and 4.0 for Class III.
