Controlflex Coupling Hub: 1° Angular Misalignment, 0.04 in Axial Motion, Inch

Double insert hubs for keyed shafts feature a slotted clamp with a machined keyway, secured with a socket cap screw to firmly grip the shaft without marring. The addition of a keyway allows for more reliable torque transmission. These hubs have longer connecting pins to accommodate the installation of two controlflex inserts between the two hubs.
