This Hi-Q Coupling Half from Maurey Manufacturing features a 0.88 inch bore and a 3/16 inch key, designed to prevent metal-to-metal contact and compensate for minor angular and center line misalignments.
Common applications include coupling hydraulic pumps to electric motors. The coupling is precision machined and rust resistant for fast installation. It is rated to 13.1 HP with a Buna-N spider and 28.8 HP with a Urethane spider, based on driving hydraulic pumps at 1800 RPM.

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.
