BM6 BMT OMT Series Motor | 6K-310 6K-490 6K-985 | Heavy Duty Orbital Hydraulic Motor

BM6 / BMT / OMT / 6K Series Heavy-Duty Disc Valve Orbital Motors

Product Overview: The BM6 Series (Equivalent to BMT, OMT, and 6K) is a high-performance, Low Speed High Torque (LSHT) orbital motor engineered for extreme duty cycles. Utilizing advanced Disc Valve technology and a Geroler gear set with precision rollers, the BM6 range delivers superior starting torque and smooth operation under high-pressure conditions. This category features the full displacement matrix: 245, 310, 390, 490, 630, 800, and 985. These motors are the industry choice for rotary drill heads, heavy-duty winches, marine cranes, injection molding machines, and large-scale harvesting equipment.

Key Technical Advantages:

• Extreme Load Capacity: Integrated with heavy-duty tapered roller bearings, the motor handles massive axial and radial loads, ideal for direct-wheel drives or high-tension sprocket applications.

• Superior Volumetric Efficiency: The disc valve distribution system automatically compensates for wear, maintaining consistent torque and efficiency throughout its service life.

• Geroler Technology: Precision rollers reduce internal friction and increase mechanical efficiency, ensuring pulse-free operation at ultra-low speeds.

• Rugged Sealing System: Equipped with premium high-pressure shaft seals to withstand significant backpressure spikes, ensuring leak-free performance in harsh environments.

• Technical Spec Decoding:

  • BM6 / BMT / OMT: Interchangeable designations for this heavy-duty disc valve frame size.

  • 6K Series: Corresponds to the international 6000 Series industry standard.

  • 245 – 985: Denotes displacement per revolution (cc/rev).
