45M155A-11A20 Vane Motor | 100% Vickers Compatible | High Torque | YHDE
Product Overview: Unleash Maximum Torque for Heavy-Duty Drives
When your system demands the highest torque density available in a vane configuration, the Vickers 45M155A-11A20 is the industry standard. As the largest displacement model in the 45M series, this motor is specifically engineered for high-load applications like heavy winches, industrial mixers, and large-scale conveyor drives.
At YHDE, we leverage over 9 years of specialized manufacturing history in our Foshan facility to provide 100% "drop-in" replacements that match every original Eaton Vickers dimension. Our 45M155A series allows you to maintain peak performance on your heavy machinery without the long lead times and premium costs of original equipment.
Key Performance Benefits
Maximum Displacement: Delivering 155 lb-in per 100 psi (241 ml/r), providing the necessary power for high-inertia startups.
100% Interchangeability: Directly replaces original Vickers 45M155A units. Mounting, porting, and shaft dimensions are identical for a seamless swap.
Dual-Vane Efficiency: Our precision-engineered internal cartridge minimizes friction and wear, ensuring consistent torque even in the most demanding 2026 production environments.
100% Load Tested: Every unit undergoes a rigorous full-load performance test at our factory to verify volumetric efficiency and seal integrity.
Factory-Direct Value: By sourcing from YHDE, you gain direct engineering support and eliminate middleman markups.

Expert Risk Reminder: The "Life-Saving" Case Drain Detail
As a skeptical expert, I must warn you about a common failure point for the 45M155A: Case Drain Negligence.
Risk Warning: Due to the massive displacement of this motor, internal leakage is naturally higher than smaller models. You MUST connect the external case drain line directly to the reservoir. If the case drain is blocked or restricted, the internal pressure will instantaneously blow out the shaft seal and may cause irreversible damage to the internal cartridge kit. Always check your drain line flow before full operation.
