Question by: Tammy F on Jul 3, 2025, 3:11 PM

Got a hydraulic pump I'm trying to mate up to an electric motor and wondering if this coupling half will handle that kind of setup?

Answer by: Customer Support on Jul 5, 2025, 6:16 AM

Coupling hydraulic pumps to electric motors is exactly what this part is built around. The Hi-Q half is machined cast iron, so it holds up well in industrial use, and it compensates for minor misalignments which is a real help when you're lining up a pump and motor in the field. Just keep in mind the angular offset tolerance is 1 degree and the parallel offset tops out at 0.015 inches, so your alignment still needs to be reasonably close before you button everything up.

got a 7/8 shaft with a 3/16 keyway, is this the right coupling half or am i off a size

Answer by: Customer Support on Jun 11, 2025, 9:52 PM

This one matches a 0.875 inch (7/8) bore and a 3/16 inch key, so it lines up with a 7/8 shaft that uses a 3/16 key.
