Jmp Equipment Company 118723 Bg Coupler 1/4-1/3 Hp

Product Description

The JMP EQUIPMENT COMPANY 118723 is a BG-style motor coupler rated for use with fractional horsepower motors in the 1/4 to 1/3 HP range. Couplers of this type serve as the flexible drive connection between a motor shaft and a blower wheel or pump impeller, absorbing minor misalignment and reducing vibration transfer during operation. This part is typically installed by HVAC technicians and equipment service professionals during motor replacements or blower assembly rebuilds.

This coupler is suited for residential and light commercial HVAC applications where BG-frame motors are used to drive blower assemblies. It is commonly encountered during evaporator blower motor replacements in split-system air handlers and package units. Proper coupler selection depends on matching the motor HP rating and shaft size to the application requirements.
