Note:
- A simultaneous maximum torque and maximum speed are not recommended.
- ∆Bar refers to true pressure difference between inlet port and outlet port.
- Continuous Rating means that the motor may be run continuously at these ratings.
- Intermittent operation refers to that the motor running time must not exceed 10% per minute under this condition.
*To assure the best orbital motor life, run it for approximately one hour at 30% of rated pressure before application to full load. Be sure this motor is filled with fluid before any load applications.

Tips: Reasons for bubbles in hydraulic orbital motor
When the hydraulic orbital motor is being transported, a small amount of gas will be suspended in the gear oil as a spherical bubble with a small diameter during filling. Gas and gear oil melt into each other and will not change the physical properties of gear oil, but when gear oil melts some amount of gas and becomes saturated, it melts because of a sudden drop in pressure when it flows through the overflow valve or the inlet of the pump. A part of the saturated gas in the gear oil will be separated out and slowly gathered together, resulting in large bubbles.
Suppose the oil level in the hydraulic orbital motor's hydraulic oil tank is too low. In that case, the returned gear oil will appear on the surface of the oil tank and cause a lot of bubbles, and if the oil inlet pipe and the inlet of the hydraulic pump leak, there will be a lot of bubbles. The gas enters the hydraulic circulation system and bubbles appear.
