High Torque Hydraulic Motor | BMK6-315, BMK6-500, BMK2-400 | Geroler Disc Valve Motor

BMK2 & BMK6 Series High Torque Geroler Hydraulic Motors

Product Overview: The BMK Series hydraulic motors are high-performance driving units specifically engineered for heavy-duty industrial and mobile machinery. Utilizing advanced Geroler parameter sets and Disc Valve technology, these motors ensure exceptional volumetric efficiency even at ultra-low speeds. This selection features core models, including the heavy-duty BMK6 Series (315cc, 250cc, 500cc) and the versatile BMK2 Series (125cc, 400cc). BMK motors are capable of handling extreme output torque and side loads, making them the premier choice for agricultural machinery, rotary drilling rigs, plastics machinery, and conveyor systems.

Key Technical Advantages:

• Disc Valve Design: The independent distribution valve provides more precise oil flow, significantly enhancing mechanical efficiency and extending service life under high-pressure conditions.

• Geroler Technology: Compared to standard gerotors, the roller structure minimizes friction, delivering superior starting torque and smoother low-speed operation.

• High Back Pressure Tolerance: Equipped with high-pressure shaft seals, these motors can operate under substantial back pressure environments, often eliminating the need for an external drain line.

• Superior Side Load Capacity: The BMK6 series is fitted with large-scale tapered roller bearings, allowing the motor to drive heavy implements directly without additional bearing supports.

• Target Applications: Heavy-duty winches, rotary drill power heads, injection molding screws, combine harvester drives, and various heavy-duty material handling systems.
