·雙滾動軸承設計,具有更大的側向承載能力。
·可靠的軸密封設計，承受背壓高，可以串并聯使用。
·正反轉換向方便、轉速平穩。
·多種油口、輸出軸、法蘭等連接形式。  

Characteristic features：
It adapts the gerolor design, which has a higher distribution accuracy and Mechanical efficiency.
Supported by double ball-bearing, the shaft can carry bigger radial force than BM2 motor.
Credible design for shaft seal, which can bear high pressure and be used in parallel or in series.
Direction of shaft rotation and speed can be controlled easily and smoothly.
Best combination of efficiency and economy in medium duty applications.

1.最大工作壓力指入口最大壓力，額定壓力指工作壓差。
2.馬達不能同時在最大壓力和最高轉速下工作。
3.在斷續工作條件下，運行時間每分鐘不得超過10%。
4.推薦用68#抗磨液壓油，粘度37-73cSt,清潔度ISO18/13。
5.最高工作油溫80°。
6.馬達全負荷工作前，應在最高工作壓力的40%以下磨合1小時。
7.馬達允許最高背壓10MPa，但建議不要超過5MPa，超過時應接外泄油管.  
Note: 
1. Intermittent means the entrance of maximum pressure; continuous working pressure means the differential pressure.
2. Motor should not work under the highest pressure and the maximum speed.
3. The running time should not exceed 10% under intermittent working conditions.
4. The Maximum working temperature is 80℃.
5. The maximum allowable back pressure is 10Mpa, but the recommended back pressure should not exceed 5MP, a leaking pipes is needed when exceeding.
6. One hour running time under 40% of maximum working pressure is recommended before full capacity working.
7. Recommending N68 anti-wear hydraulic oil, viscosity 37-73cSt, cleanliness ISO 18/13.
