Bores from 2 3/16" to 3". These rugged cast-iron couplings handle high torque and are longer than our other rigid couplings to maintain alignment on long shaft runs. Able to come apart in two halves, you can install and remove them anywhere on your shaft without disassembling your machinery. They clamp on for superior holding power without damaging your shaft. Tighten the six bolts (unless noted) to secure. A keyway with standard ANSI keyway dimensions (unless noted) provides a more secure hold making these coupling especially good for alternating-motion applications. Specify required bore when ordering.
