Question by: Duane B on Apr 2, 2026, 3:16 PM
got a 7/8 shaft with a 3/16 keyway. is this the right coupling half for it?
Answer by: Customer Support on Apr 4, 2026, 9:26 AM
It matches a 0.875 inch (7/8) bore and a 3/16 inch key, so it’s intended for that shaft size and key.
Question by: Billy R on Apr 27, 2025, 7:56 PM
