Our motor mounting codes can be configured automatically using our online selection tool. These tables supply the details behind these codes. The tables start with Input Bore measurement and the Part # Code, which are indicated at the end of every model code.
For each Part # Code, the Pilot, BCD, Tapped Hole, and Pilot Depth, are explained.
Please note that even though the Part# Code may have the same letters (i.e. DC, FB, HA, etc.), the Pilot and BCD dimensions may not be the same if a different input bore diameter. Locate the table by input bore diameter first, and then find the appropriate adapter Part# Code to check the dimensions. If you have any questions, contact Nidec Drive Technology for support.
