MRE1400G-F2N1N1N1NX1000 Parker Radial Motor 250Bar

Product Overview:

The MRE1400G-F2N1N1N1NX1000 is a world-class, Low-Speed High-Torque (LSHT) radial piston motor built for the most demanding heavy-duty applications. Engineered as a premium, 100% interchangeable alternative to the Parker Hannifin (Calzoni) MRE series, it perfectly mirrors the original flange dimensions, spline specifications, and port alignments for a seamless “Plug & Play” integration. Unlike traditional cam-lobe motors, the MRE series utilizes Calzoni’s iconic eccentric crankshaft and telescoping cylinder design. This rod-less architecture eliminates lateral friction, delivering extraordinary mechanical efficiency and starting torque. To guarantee uncompromised industrial-grade reliability, every single motor is subjected to 100% simulated full-load dynamic testing, ensuring your equipment operates flawlessly under extreme conditions.

Key Technical Advantages:

• 100% True Interchangeability: Precision-manufactured to match the exact dimensional tolerances of the OEM Parker Calzoni MRE1400G. It functions as a zero-risk, cost-effective replacement for plastic injection machines and marine winches without requiring structural modifications.

• Frictionless Rod-less Design: By eliminating the connecting rods and utilizing a patented telescoping cylinder system, the hydrostatic pressure is transmitted directly to the eccentric shaft. This removes lateral forces, allowing mechanical efficiency to reach up to 96% and significantly reducing heat generation.

• Exceptional Starting Torque: Thanks to its low internal friction and brilliant hydrostatic balancing, the motor delivers massive starting torque from 0 rpm and guarantees incredibly smooth rotation at speeds as low as 1-2 rpm, entirely free of the “cogging” effect.

• 100% Dynamic Load Testing: We do not believe in batch sampling. Every assembled unit undergoes rigorous full-power testing on our hydraulic benches, including pressure spiking, full-speed operations, and internal leakage checks, ensuring absolute zero-defect delivery.

Application Areas:

Benefiting from its precise low-speed controllability and high radial load capacity, this motor is the ultimate drive solution for:

• Plastics & Rubber Machinery: Plasticizing screw drives in injection molding machines and large extruders.

• Marine & Offshore: Anchor windlasses, heavy-duty towing winches, and deck cranes.

• Mining & Metallurgy: Heavy scraper conveyors, ball mill drives, and steel rolling drives.

Expert Maintenance Tips:

• Pre-fill the Case: Despite its high mechanical efficiency, dry running is fatal. Before the initial start-up or after prolonged storage, the motor housing must be completely filled with clean hydraulic fluid through the highest case drain port to establish an essential lubricating film.

• Control Case Drain Pressure: The main shaft seal in eccentric shaft motors is sensitive to pressure spikes. Ensure the continuous case drain pressure does not exceed 1 bar. Always route the case drain line directly to the reservoir, independent of return lines.

• Fluid Cleanliness: The micro-clearances of the hydrostatically balanced components require pristine fluid. Maintain a fluid cleanliness level of at least ISO 4406 18/16/13 and use a 10μm absolute return line filter to maximize component longevity.
