Help finding a shaft coupling 7/8" --> 5/8"?
Help finding a shaft coupling 7/8" --> 5/8"?
(OP)
It seems nobody makes a shaft coupling that steps down 1/4" from 7/8" to 5/8". I am looking for a clamp-style coupling. Hooking up a gearbox that has an output shaft of 7/8" DIA with a 3/16" keyway to a ball-screw setup that has a shaft size of 5/8" DIA with a 3/16" keyway. Any ideas of someone that makes one that can handle these sizes, with or without the keyway? Thanks.

Mcmaster has rigid couplers with a fixed 7/8" bore on one side and a machinable-bore (.235" pilot hole) on the other side that you could enlarge to size. (part number 3084K47)
They also have step up/down clamp on shaft adapters.. (like part number 9783T2)
Have you tried Misumi?.. They have a large selection too.

Just google 7/8-5/8 shaft coupling
