Vickers M Series Motor | 25M 35M 45M 50M | High Speed Hydraulic Vane Motor

Vickers M Series High-Speed High-Pressure Balanced Vane Motors

Product Overview: The Vickers M Series vane motors are the industry standard for power in both industrial and mobile hydraulic systems. This category encompasses the full range from compact 25M/26M and mid-size 35M to heavy-duty 45M/50M frames. We highlight precision specifications: 45M185A1C-20, 25M65A11C20, 26M42A1C20, and 25M55A1C20. Engineered with the renowned hydraulically balanced architecture, these motors neutralize internal radial loads, ensuring exceptionally long bearing life under high-speed and high-pressure cycles. They are the premier choice for injection molding screw drives, marine winches, material handling machinery, and metal-cutting equipment.

Key Technical Advantages:

• Fully Balanced Architecture: Internal forces are automatically offset to eliminate radial bearing loads, drastically increasing reliability during demanding duty cycles.

• Low Startup Torque Loss: Precision-engineered vane-tip sealing ensures superior breakout performance under load, eliminating “cogging” or instability at low speeds.

• Bi-rotational Versatility: The symmetrical design supports consistent bi-directional rotation, maintaining high mechanical efficiency through frequent start-stop and reversing cycles.

• Modular Cartridge Design: Rotating elements are self-contained within a Cartridge Kit. This allows for rapid servicing without removing the motor housing from the equipment, minimizing downtime and costs.

• Technical Spec Decoding:

  • 25M / 35M / 45M / 50M: Frame size identifiers correlating to torque capacity.

  • 42A / 55A / 65A / 185A: Torque codes (lb-in/100 psi) defining displacement and power output.

  • 1C / 11C: Relates to shaft configurations (e.g., standard SAE Keyed or Splined shafts).
