This pulley is listed as "fractional hp". I need a pulley for a 5 hp electric motor. will this pulley work in my application?
A: Yes, we have had customers operate these pulleys on that horsepower, as long as the motor rpm does not exceed 1750 rpm. At higher speeds the allowable speed of the pulley itself is exceeded. Whether it will work in your application is your decision, using that information.
