H Couplings
The life expectancy of couplings is determined by tightening torque, bend angle, and axle core displace-
ment volume.
D Tightening Torque and Rotation Life
Tightening torque (%)
Rotation life expectancy (No. of rotations)
Note Tightening torque is given as a percentage of allowable tightening torque. (Refer to 2-2-3 Mount-
ing the Resolver.)
D Bend Angle and Rotation Life
Bend angle (%)
Rotation life expectancy (No. of rotations)
Note Bend angles are given as a percentage of allowable bend angles. (Refer to 2-2-3 Mounting the
Resolver.)
