How to use the table<\/h2>\n

First exclude sizes that cannot accept either shaft. Then compare the actual operating speed with the reference maximum for the candidate size. Finally review torque or motor duty. If the installed unit is a replacement, include its marking and measured hub dimensions so a model-name mismatch can be caught before quotation.<\/p>\n
