MS18-2-124-F19-1410-5800 Poclain Radial Motor 400Bar

Product Overview:

The MS18-2-124-F19-1410-5800 is a heavy-duty, low-speed high-torque (LSHT) radial piston motor engineered for the most demanding mobile and industrial applications. Designed as a top-tier alternative to the original Poclain Hydraulics MS18 series, this motor offers 100% true interchangeability. Its mounting flanges, shaft dimensions, and fluid ports perfectly mirror the OEM specifications, ensuring effortless “Plug & Play” installation without any machine modifications. Equipped with an upgraded F19 high-capacity wet multi-disc parking brake, it guarantees superior holding torque for enhanced safety in heavy-load scenarios. To uphold our rigorous quality standards, every single motor undergoes 100% simulated load and dynamic testing prior to dispatch, guaranteeing peak operational readiness and drastically reducing your total cost of ownership.

Key Technical Advantages:

• 100% True Interchangeability: Precision-machined to match the exact tolerances of the Poclain MS18 footprint. Whether used for aftermarket replacement or OEM assembly, it integrates seamlessly, significantly cutting down procurement costs and downtime.

• Heavy-Duty F19 Brake System: Compared to standard brakes, the integrated F19 wet multi-disc brake provides a larger friction surface and exceptional static holding torque. It acts as a fail-safe parking mechanism, ideal for mining vehicles or machinery operating on steep inclines.

• Fatigue-Resistant Cam Ring: The core cam ring is forged from premium alloy steel and deeply carburized for maximum hardness. The optimized cam-lobe profile ensures uniform piston loading, delivering massive starting torque and perfectly smooth rotation without low-speed cogging.

• 100% Dynamic Load Testing: We do not rely on batch sampling. Every assembled unit is rigorously tested on our hydraulic test benches. From pressure retention and low-speed stability to brake actuation and thermal cycling under full load, we guarantee zero-defect deliveries.

Application Areas:

Powered by extreme load-bearing capabilities and robust F19 braking, this motor excels in heavy machinery such as:

• Mining Equipment: Underground LHD loaders, heavy drill rigs, and wheel drives for mining dump trucks.

• Construction Machinery: Large tonnage road rollers, crawler excavator drives, and horizontal directional drills (HDD).

• Heavy Industrial Systems: Industrial scrap shredders, tunnel boring machine (TBM) cutter heads, and heavy marine winches.

Expert Maintenance Tips:

• Verify Brake Release Pressure: The F19 brake utilizes high-tension internal springs. Before operating the main drive, ensure the pilot pressure to the brake release port reaches a minimum of 15 bar. Inadequate release pressure will cause the motor to drive through the brakes, destroying the friction discs within minutes.

• Pre-fill the Housing: Never start the motor dry. Before the initial run or after prolonged storage, the main motor housing must be completely filled with clean hydraulic fluid via the highest case drain port to properly lubricate the main bearings and piston rollers.

• Control Case Drain Pressure: To prevent catastrophic shaft seal blowouts, strictly maintain the internal case drain pressure below 2 bar. Route the case drain line directly to the reservoir, and never manifold it with high-pressure return lines.
