Hydraulic Coupling

This general-purpose industrial coupling is designed to mechanically connect two rotating shafts of different diameters, accommodating a 1-1/4? bore on one end and a 1-7/16? bore on the other. It transmits torque between a motor or pump and the driven equipment, making it suited for use in food processing applications such as grinders, conveyors, mixers, and stuffers.

Each bore is machined with a keyway to ensure fixed shaft phasing and to increase torque-carrying capacity beyond what friction alone provides. This configuration allows for reliable, slip-resistant power transfer between a hydraulic motor or gearbox output shaft and the connected machine drive shaft.

The coupling is intended for general industrial service where two shafts of differing diameters must be joined in a direct-drive arrangement without alignment compensation.
