With a bore of 1.125 inches and a key of 1/4 inch it offers horsepower ratings of 3.2 for Buna-N and 5.0 for Urethane. The coupling maintains performance within a temperature range of -20F to 180F for Buna-N and -80F to 180F for Urethane.

Question by: Howard H on Jun 1, 2025, 6:24 PM
got a 1-1/8" shaft with a 1/4" keyway. is this the right coupling half for that?
Answer by: Customer Support on Jun 3, 2025, 6:03 PM
It matches a 1.125 inch bore with a 1/4 inch key, so it’s intended to go on a 1-1/8 inch keyed shaft.
