Vickers 45M & 46M Series Heavy-Duty Balanced Vane Hydraulic Motors

Product Overview: The Vickers 45M and 46M Series are high-capacity, fixed displacement vane motors engineered for the most demanding industrial environments. Renowned for their exceptional reliability and high efficiency, these motors are the industry choice for marine winches, deck machinery, injection molding screw drives, material handling cranes, and forming presses. This category features the core precision models: 45M130A-11C20, 45M155A, 45M185A, and the reinforced 46M185A-1A20. Its unique hydraulically balanced design minimizes internal loads, ensuring an extended service life even under high-pressure cycles and frequent start-stop duty.

Key Technical Advantages:

• Hydraulically Balanced Architecture: The internal rotor is balanced to eliminate radial loads on the bearings, ensuring smooth operation and dramatically extended component life under high pressure.

• Modular Cartridge Kit Design: Rotating elements are contained within a self-contained cartridge, allowing for rapid on-site replacement without removing the motor housing from the installation, significantly reducing downtime.

• Superior Startup Torque: Optimized vane-tip technology ensures excellent breakout performance under heavy loads, reducing vibration during initial rotation.

• High-Pressure & Rapid Response: Engineered for rigorous pressure cycles and frequent reversals, delivering perfectly symmetric performance in both clockwise and counter-clockwise directions.

• Technical Spec Decoding:

  • 45M / 46M: 45M is the standard heavy-duty series; 46M is the reinforced version optimized for higher pressure thresholds.

  • 130A / 155A / 185A: Torque displacement codes (lb-in/100 psi), representing 130, 155, and 185 torque levels respectively.

  • 1A20 / 1C20 / 11A20: Precise codes relating to mounting flanges (e.g., SAE C) and shaft ends (Keyed or Splined).
