    BK2 Orbit Motor FAQ:


    1. What is the BK2 Orbit Motor?

    BK2 orbit motor is a disc-distributed geroler hydraulic motor, fully interchangeable with Eaton Char-Lynn 2000 series. It features compact size, large starting torque and stable low-speed operation. With reinforced bearings to bear heavy radial and axial loads, it covers multiple displacements for agricultural, construction, sanitation and forestry machinery drive.


    2. What makes the BK2 Orbit Motor ?


    • Advanced disc compensation geroler structure, high volumetric efficiency and long service life

    • Low startup pressure, smooth low-speed rotation without crawling, stable forward/reverse running

    • Reinforced output bearing, capable of heavy radial and axial load

    • Max continuous pressure up to 21MPa, peak pressure reaches 31MPa for heavy overload

    • Complete displacement lineup and multiple shaft/flange options for flexible matching

    • Fully interchangeable with Eaton Char-Lynn 2000 series for direct replacement

    • Compact layout, low noise vibration and reliable anti-leak sealing performance


    3. What is the working pressure range of
    BK2 Orbit Motor ?

    • Continuous working pressure: 20.5–21 MPa (205–210 bar)

    • Intermittent pressure: 26–31 MPa (260–310 bar)

    • Instant peak pressure: Max 31 MPa (310 bar)

      Note: Peak pressure is only allowed for short-time overload operation. Long-term running shall stay within continuous rated pressure to extend motor service life.

    4. Can BK2 Orbit Motor replace other brands?



    Yes, BK2 orbit motor is a direct drop-in replacement for multiple mainstream brand models without modifying installation frames or hydraulic pipelines.
    1. Perfect interchange with Eaton Char-Lynn 2000 / 2K series: same 2-hole SAE flange, shaft sizes, port layout and torque-speed performance

    2. Compatible with Danfoss OMS series and M+S MS series orbit motors of matching displacement and mounting standard.

    3. Multiple optional shafts (straight key, involute spline, tapered spline) and customized port threads support matching most domestic Chinese BM2/BMS hydraulic motors.

    4. Identical pressure, torque and speed parameters guarantee consistent machine running performance after replacement.
