| Metric | Standard Orbit Motors | BM5 LSHT Series |
|---|---|---|
| Low-Speed Stability | Moderate Pulsation | High Stability/Smooth |
| Wear Resistance | Standard Lining | Auto-Compensation Design |
| Load Capacity | Limited Radial Load | Enhanced Double-Bearing |

The normal working oil temperature should be between 20℃ and 60℃, with a maximum allowable system operating temperature of 90℃ for no more than one hour.
When the oil return port pressure exceeds 10MPa (and rotation speed is below 200rpm), pressure relief must be conducted via the leakage port, preferably connecting it directly to the tank.
We recommend a filter filtration accuracy of 10-30 microns and a solid pollution level not exceeding 19/16. Installing a magnetic block at the bottom of the tank is highly advised.
Yes, the BM5 series motors are designed to be versatile and can be utilized in either series or parallel connections depending on your system requirements.
To maximize motor life, load the motor for one hour at 30% of the rated pressure. Always ensure the motor is completely filled with oil before applying any load.
The output shafts of the BM5, BM6, BM7, BM8, and BM10 series motors are specifically engineered to bear larger axial and radial loads.
