Poclain MK05 MK04 Hydraulic Motor | MK05-0-124-F07-1340-0000 | Compact Piston Motor

LIC Hydraulic’s Poclain MK Series represents the high-density power solution in the compact orbit motor market. Built on Poclain’s legendary Multi-cam Lobe Piston technology, the MK series (including MK04 and MK05) is specifically designed for applications where axial space is at a premium. Our models, such as MK05-0-124-F07-1340-0000 and MK04-2-114-K04-3340-3000, offer 100% seamless interchangeability. These “Compact” versions provide the same rugged torque as the MS series but with a significantly shorter footprint, making them ideal for modern wheel hub integrations and narrow-track machinery.

Technical Specifications

• Model Codes: MK05-0-124-F07-1340-0000 / MK04-2-114-K04-3340-3000

• Rated Pressure: $400\text{ bar}$ (5800 psi)

• Peak Pressure: $450\text{ bar}$ (6525 psi)

• Startup Torque Efficiency: $>90\%$

• Design Type: Radial Piston / Cam-lobe

• Key Feature: Axial length reduced by approx. 20% compared to standard MS models.

Key Technical Advantages

• Space-Saving “Compact” Profile: The MK design removes unnecessary axial bulk, allowing for easier integration into skid-steer wheel motors or horticultural tractors where narrow machine width is critical.

• Smooth Low-Speed Performance: The multi-action piston geometry ensures pulse-free torque delivery at near-zero RPMs, essential for precision construction and material handling tasks.

• Highly Integrated Options: Features modular designs for integrated parking brakes, speed sensors, and 2-speed displacement valves without increasing the motor’s envelope.

• Extreme Durability: Engineered to withstand continuous high-pressure cycles, the reinforced cam and roller sets ensure a long service life even in heavy-duty soil-working environments.

Application Areas

• Ag-Machinery: Specialized harvesters, orchard tractors, and vineyard sprayers.

• Construction: Steering systems for rollers, auxiliary drives for pavers, and mini-excavators.

• Material Handling: Compact wheel drives for forklifts and telescopic handlers.

• Marine & Industrial: Small-scale winches and deck machinery.

Expert Maintenance Tips

• Case Flushing Best Practice: For high-load or continuous-duty cycles, we recommend a case flushing flow to manage internal temperatures and extend the life of the cam-lobe interface.

• Oil Cleanliness: Given the precision of cam-lobe systems, maintain oil at ISO 18/16/13. Particle contamination can cause rapid scoring of the cam track.

• Port Orientation: Ensure all ports are oriented correctly during installation, especially the case drain. A blocked drain line will result in immediate shaft seal failure due to high internal case pressure.
