Note 1: The temperature 80° includes temperature rises during rotation.
Note 2: The starting rotational torque does not change with the supply pressure or with non-use (remains within starting allowable rotational torque), but it does change with the rotational speed.
Note 3: If using at a speed above 600 min^-1 (r.p.m.), ensure rotation is in the direction in which the joint is fastened.
Note 4: Rubber/resin couplings are recommended due to their excellent absorption of off center misalignments, shocks and vibrations.
Note 5: min^-1 is the number of rotations per minute.
