MB Series High-Performance External Hydraulic Gear Motors

Product Overview: The MB Series is a premier fixed-displacement external gear motor engineered for medium-to-high pressure industrial and mobile applications. Featuring a high-strength extruded aluminum alloy housing and precision-ground gear sets, the MB series delivers exceptional power density within a compact footprint. This category covers the full matrix from MB1 to MB8, highlighting precision models: MB1AK692, MB2AK692, MB3AK692, MB4AK692, MB5AK692, MB6AK692, MB7AK692, and MB8AK692. These motors are the industry choice for agricultural fan drives, conveyor systems, street sweeper hydraulics, and industrial hydraulic power units.

Key Technical Advantages:

• Elite Pressure Compensation: Integrated axial floating plates automatically adjust clearances based on operating pressure, maintaining superior volumetric efficiency across the entire performance curve.

• Heavy-Duty Load Tolerance: Equipped with high-performance composite bushings to handle significant radial loads, ensuring operational reliability at high RPMs.

• High-Pressure Shaft Seal: Features specialized sealing technology that handles significant back pressure, often eliminating the need for an external case drain line in standard circuits.

• Universal Interchangeability: Fully compliant with international mounting standards (e.g., European 4-bolt or SAE). The AK692 configuration ensures seamless drop-in replacement.

• Technical Spec Decoding:

  • MB1 – MB8: Denotes frame sizes and displacement ranges (cc/rev).

  • AK692: Detailed code correlating to mounting flange specs, shaft ends (Tapered 1:8 or Keyed), and porting configurations.
