M3X800ACN-005A Kawasaki M3X Hydraulic Motor 29.4MPa

Product Overview

The M3X800ACN-005A (P-37WXQ005A), M3X200ACN-004A (P-37E004A), M3X280ACN-001A (P-37G001A) and M3X530ACN-501A (P-37L501A) belong to the Kawasaki M3X series of fixed-displacement swash-plate axial piston motors. Designed for mobile and industrial applications, these motors offer excellent self-priming capability and high starting efficiency, built on Kawasaki’s extensive experience with swash-plate technology. Manufactured to original specifications with full dimensional, interface and performance interchangeability, every unit undergoes 100% simulated duty-cycle testing to ensure low-speed performance, smooth starting, torque output and service life equal to or exceeding genuine Kawasaki standards. Ideal for high-load drive systems such as crushers, cranes and drill rigs.

Key Technical Advantages

1. Superior low-speed performance and smooth starting: Optimized swash-plate and rotary-group design significantly reduces pressure ripple and friction, extending the low-speed operating range and delivering stable starting torque ideal for frequent start-stop heavy-duty cycles.
2. High starting efficiency and self-priming capability: Leveraging Kawasaki’s proven swash-plate technology, the motors provide excellent self-priming characteristics that minimize auxiliary system requirements and improve overall transmission efficiency.
3. Robust construction and long-life bearings: High-strength materials and precision manufacturing support intermittent high-pressure and continuous-duty operation; optional parking brake enhances suitability for demanding mobile environments.
4. Full interchangeability and 100% duty-cycle testing: Mounting flanges, shaft ends, ports and control interfaces match original Kawasaki M3X units exactly. Every motor is tested under simulated pressure, flow, torque, leakage and noise conditions prior to shipment for true plug-and-play reliability.

Application Areas

Mobile crusher drives, crawler and rough-terrain cranes, drill and pile-driving rigs, tunnel boring machines, plastics and die-casting machinery, cargo vessels, oil tankers, offshore vessels, industrial vehicles and any hydraulic drive system requiring high torque and reliable low-speed operation. Can be combined with RG series reduction gears for expanded capacity coverage.

Expert Maintenance Tips

Ensure adequate inlet supply to prevent cavitation; fully bleed the system and verify correct rotation direction before first start-up. Use hydraulic fluid meeting recommended cleanliness and viscosity ranges (typical operating oil temperature –20 °C to 90 °C). Regularly monitor case-drain temperature and bearing condition; avoid over-pressure or over-speed operation. When replacing, always confirm the complete type code (including ACN configuration suffixes) so that control valves and brake options match the original machine. For long-term storage, drain the fluid and apply corrosion-protective oil; inspect seals and interfaces before recommissioning.
