Product Questions & Answers

what's the horsepower limit on one of these if I'm running a hydraulic pump off a standard 1800 RPM electric motor?
Question by: Gene E on Dec 21, 2025, 8:44 PM
At 1800 RPM driving a hydraulic pump, the rating is 3.2 HP with a Buna-N spider and 5.0 HP with a urethane spider. Those numbers already account for a service factor of 1.5, so they reflect real working conditions rather than theoretical maximums. If your motor falls outside that speed, the rating will shift, but at 1800 RPM those are your numbers.

trying to match up a coupling half i’ve already got, is this one a 1/2 inch bore with a 1/8 keyway?
Question by: Dean H on Feb 3, 2026, 5:09 PM
It matches a 0.50 inch bore and a 1/8 inch key, and the supplier part number is L095-1/2-W-1/8K.

got a 1/2 inch shaft with a 1/8 keyway. is this coupling half the right fit or am i missin somethin
Question by: Denise C on Jun 22, 2025, 8:46 AM
Fit comes down to the bore and key size, and this one is set up for a 0.50 inch bore with a 1/8 inch key. It is the Hi-Q coupling half style used in flexible couplings, so it matches that shaft size and key requirement as stated.

what's the temperature range on this thing if i'm running a urethane spider versus the buna-n? trying to figure out which setup makes more sense for where we're using it
Question by: Carl R on Jan 15, 2026, 8:11 PM
Buna-N spiders are rated from -20°F up to 180°F, so they cover most standard shop and equipment room conditions just fine. Urethane spiders give you a wider cold-side range, starting at -80°F, with the same 180°F ceiling on the high end. If your application sees any kind of extreme cold, the urethane is the better call. For typical indoor pump and motor setups that don't get especially cold, either material will get the job done within that upper limit.
