Smaller shafts in coupling bore range and short key applications may not transmit horsepowers listed above, check shaft and key stress.

*Normal Service* Ratings are steady, non-reversing, eight hour service per day, with normal starting torque motor. Apply Service Factor per page 134 for more rugged service.

To determine torque in inch pounds at any given speed use formula: T = ~~⁶³°RPM/1^H'^P~~

Ratings for speeds less than 50 or 100 R.RM. can be determined by torque value derived from torque formula at 100 R.RM.
