Product details

1.This wide range of hydraulic vane motors allows selection of a model to suit any particular application.

2.They are used industrially where there is a need to provide a relatively high torque from a power source of small dimensions.

3.The low moment of inertia of the rotating group admits high acceleration and deceleration resulting in rapid response to system control signals.

M4E/M4SE Series Vane Motors: Technical Overview

(Engineered for High-Performance Industrial and Mobile Applications)

------

1. Product Series & Classification

• M4E Series: High-speed vane motor (144.4 ml/rev displacement), optimized for efficiency and compact design.

• M4SE Series: Heavy-duty variant of the M4E, featuring reinforced construction for extreme loads (e.g., mining, offshore drilling).

• Key Variant:M4E-024/M4SE-024(standard model) with SAE-B 2-hole flange mounting.

Parameter M4E/M4SE Details Notes

Displacement 144.4 ml/rev (fixed) Designed for medium-to-high flow systems.

Rated Pressure 210 bar (M4E), 175 bar (M4SE) Peak pressure tolerance up to 280 bar.

Max Speed 4,500 RPM (M4E-024) Speed varies with displacement.

Torque Output 12.0–85.0 Nm (at 6.9 bar) Scalable with pressure/displacement.

Mounting Options SAE-B 2-hole flange, ISO 3019-2 Side/tail port configurations available.

Weight 25.0–38.0 kg (model-dependent) Robust design for heavy-duty use.

3. Performance Advantages

• High Efficiency:

• Advanced vane profiling reduces friction loss (>90% efficiency at rated speed).

• Low noise operation (≤85 dB(A)) due to precision-balanced rotor assembly and vibration-damping materials.

• Durability:

• M4SE variant: Hardened steel shafts, tungsten carbide bearings, and high-grade seals for extreme conditions.

• Dual-lip seals with anti-extrusion rings prevent oil leakage in high-pressure environments.

• Adaptability:

• Bidirectional rotation(clockwise/counterclockwise) via port A/B switching.

• Compatible with mineral-based, fire-resistant, and biodegradable hydraulic fluids.

------

4. Key Applications

• Industrial Equipment:

• High-speed winches, hydraulic pumps, and conveyor drives in construction/material handling.

• Mobile Machinery:

• Drive systems for excavators, cranes, and agricultural tractors.

• Specialized Environments:

• Underground mining (explosion-proof design for M4SE models).

• Marine applications (corrosion-resistant coating and saltwater-resistant seals).

------

5. Installation & Maintenance

• Port Configuration:

• SAE 4-bolt, UNC thread, or metric thread options.

• Optional integrated relief valves and pressure sensors for advanced control.

• Service Recommendations:

• Replace hydraulic oil every 1,500–3,000 hours (depending on operating conditions).

• Inspect seals, bearings, and vane tips quarterly for wear.

------

6. Customization & Support

• Tailored Solutions:

• Adjustable pressure ratings (up to 280 bar) for custom systems.

• Special coatings for extreme temperatures (-30°C to +120°C).

• Supplier Network:

• Global availability through distributors (e.g., Denison Hydraulics, Eaton).

• Technical support for system integration, failure analysis, and troubleshooting.

------

7. Competitive Comparison

【表格】

Metric M4E/M4SE Alternative Brands (e.g., Parker, Bosch Rexroth)

Load Capacity High (M4SE for heavy-duty) Comparable, but fewer high-speed options.

Noise Level ≤85 dB(A) Slightly higher in some models.

Customization Extensive port/mount options Limited to standard configurations.
