Normal Service Ratings are steady, non-reversing, eight hour service per day, with normal starting torque motor. Apply Service Factor per page 37 for more rugged service.
63025 x H.P.
To determine torque in inch pounds at any given speed use formula:
T =
R.P.M.
Neoprene mold designations of S and N are one in the same
Couplings with Bronze Inserts limited to 250 RPM.
Ratings for speeds less than 50 or 100 R.P.M. can be determined by torque value derived from torque formula at 100 R.P.M.
Small shafts in coupling bore range and short key applications may not transmit horsepowers listed above, check shaft and key stress.
Bronze inserts may be noisy on some applications.
