Baldor-Dodge 120431 QD Bushing

The Baldor-Dodge 120431 QD Bushing is a quick-disconnect style shaft-hub interface designed for Baldor-Dodge power transmission assemblies. It has a bore diameter of 1-5/8 in and a barrel diameter of 2.81 in, with the part number 120431 used to identify this specific item. This bushing provides the essential inner bore for the shaft and an outer barrel that engages with a compatible hub or drive component in the Baldor-Dodge family. The exact fit is defined by those two dimensions, ensuring proper alignment and fit in installations that call for a QD mounting approach. This type of bushing is selected when removable, serviceable connections between rotating parts are required, enabling quicker disassembly for maintenance or replacement compared to more permanent mounting options. When specifying the 120431, confirm that your shaft diameter matches the 1-5/8 in bore and that the mating hub can accommodate a 2.81 in barrel to ensure a secure, accurate assembly.
