Disengageable Couplings
These couplings have a rugged, time tested design. They are best suited for starting, stopping, and reversing motions. Their most unique feature is the ability to engage and disengage a second in-line shaft upon demand. Misalignment is acceptable in these couplings up to .020” out of parallel and up to ½° angularity.
