Description & Features

The Hi-Q Coupling Half with a 1.00-inch bore and 1/4 inch key provides superior performance in various applications. This flexible coupling is engineered by Maurey Manufacturing Co renowned for its precision-ground and machined parts. Its design effectively prevents metal-to-metal contact compensating for minor misalignments and ensures rust resistance. Quick installation is facilitated by its sintered metal construction suitable for coupling hydraulic pumps to electric motors. Designed to handle a temperature range of -20F to 180F with a Buna-N spider this coupling can also accommodate temperatures from -80F to 180F using a urethane spider. The horsepower rating for Buna-N is 3.2 while for urethane it is 5.0.

Question by: Stan F on Jun 30, 2025, 7:07 AM

What size key do I need for this coupling half? Quarter inch, right?

Answer by: Customer Support on Jul 1, 2025, 12:38 PM

it's designed for a 1/4 inch key.

Question by: Dale B on Apr 16, 2025, 8:55 PM

What kind of temperatures can this coupling handle? We run equipment in a cold storage facility and need something that won't get brittle on us in winter.

Answer by: Customer Support on Apr 18, 2025, 6:04 AM

Cold storage should be fine depending on which spider element you pair with it. The Buna-N spider holds up from -20F down to 180F on the high end, but if your facility gets colder than that, the urethane spider version extends the low end all the way down to -80F. Either way the upper limit stays at 180F, so heat isn't usually the concern in your situation. Just make sure you're specifying the urethane spider when ordering if those temperatures dip real low.

got a 1 inch shaft with a 1/4 keyway, is this coupling half the right fit?

Answer by: Customer Support on Feb 23, 2026, 6:10 AM

It matches a 1.00 inch bore and a 1/4 inch key, so it’s made for that shaft and key size combination.
