GMC4 Series High-Pressure Cast Iron Gear Motors

Product Overview: The GMC4 Series is a fixed-displacement hydraulic gear motor engineered for the most punishing industrial and mobile environments. Featuring a high-strength cast iron housing and a three-piece construction, the GMC4 series provides exceptional stability under extreme pressures and load fluctuations. This category covers the full matrix from 20cc up to 80cc, highlighting precision models: GMC4-20-B2F-11 and GMC4-25-B2F1-30. These motors are the premier choice for mower drives, sweeper hydraulic systems, wood processing machinery, and heavy-duty mobile equipment.

Key Technical Advantages:

• Cast Iron Ruggedness: Compared to aluminum gear motors, the cast iron build withstands higher internal pressures and external impacts, ensuring quieter and smoother operation at high RPMs.

• Superior Volumetric Efficiency: Precision-engineered pressure balance plates automatically compensate for clearance via lateral pressure, maintaining high efficiency even under high-temperature and high-pressure conditions.

• Heavy-Duty Bearing Support: Equipped with reinforced needle bearings, allowing the motor to handle radial loads typical of sprocket or gear-driven applications.

• Highly Configurable: Available with various mounting flanges (e.g., B2F) and specific shaft configurations (indicated by -11 or -30 codes) for seamless machinery integration.

• Technical Spec Decoding:

  • GMC4-20 / 32 / 80: Denotes displacement per revolution (cc/rev).

  • B2F / B2F1: Relates to mounting flange standards (e.g., SAE or European specs).

  • -11 / -30: Represents diverse shaft types, such as keyed, splined, or specialized tapered shafts.
