High Torque BM6 BMT OMT 6K Series Hydraulic Motor | 6K-490, 6K-625, 6K-800, 6K-985

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

Product Overview: The BM6 Series (Equivalent to BMT, OMT, and 6K Series) represents the performance standard for large-displacement geroler motors. Engineered with advanced Disc Valve technology and Geroler gear sets, this series is specifically designed for consistent, high-torque output at low speeds. This range highlights heavy-duty specifications: 6K-490, 6K-625, 6K-800, and the ultra-large 6K-985. Featuring integrated tapered roller bearings, these motors can withstand significant radial and axial loads, making them the definitive drive choice for heavy-duty winches, rotary drilling rigs, and complex conveyor systems.

Key Technical Advantages:

• Superior Starting Torque: The geroler gear set minimizes friction, ensuring smooth start-up at low pressures and providing full torque output immediately.

• High-Pressure Shaft Seal: Equipped with high-performance shaft seals as standard, allowing the motor to handle high back-pressure without the need for an external drain line.

• Excellent Low-Speed Stability: The precise disc valve mechanism automatically compensates for wear, maintaining smooth operation even at speeds as low as a few RPM.

• Heavy-Duty Load Capacity: The drive shaft is supported by two large tapered roller bearings, allowing the motor to directly drive heavy-duty wheels or winch drums.

• Target Applications: Rotary drilling rig power heads, marine winches, heavy-duty injection molding machines, road sweeper brush drives, agricultural harvesters, and specialized industrial conveyors.
