Industrial CHC5016 Keyed Coupling Half One And One Quarter Inch Bore

Industrial CHC5016 keyed coupling half with a 1-1/4 in bore. This half of a two-piece keyed shaft coupling transmits torque between shafts in mechanical power transmission systems. The "keyed" design uses a machined keyway in the hub to mate with a corresponding shaft key, preventing slip and maintaining proper angular alignment. The 1-1/4 inch bore specifies the shaft diameter it accepts and works with standard coupling hardware to secure the assembly. The CHC5016 part number identifies this specific coupling half within an industrial family designed for pairing with a matching half to form a complete, torque-ready connection. In typical industrial setups, this half is paired with a matching CHC5016 mate to form a complete, torque-transmitting coupling, enabling reliable performance in drive trains where positive engagement is required.
