The Rotortorc gear set employs an interlocking set of teeth making them suitable for long operating periods at moderate pressures or short operating periods at high pressures.

For optimal utilization of these motors, the following is recommended:

1. Normal oil operating temperature should be 70° t 150°F (20° to 60°C)
2. Maximum operating temperature should not exceed 190°F (90°C)
3. Filtration level per ISO Cleanliness Code level 18/3.
4. Minimum oil viscosity should be 100 SUS.
5. Motors should be operated at less than 30% of rated performance for the first hour of operation.
6. Simultaneous maximum torque and maximum speed is NOT recommended.
