Product details

1. Product Positioning

• Core Component: The MR450E is a critical piston assembly used in high-performance hydraulic motors manufactured by Nabtesco (Japan) or similar hydraulic system providers.

• Applications: Primarily deployed in construction machinery (e.g., excavators, loaders, drill rigs), agricultural equipment (harvesters, tractors), and industrial hydraulic drive systems.

2. Structure & Function

• Materials:

• Piston Body: High-strength alloy steel (e.g., 42CrMo4) with heat treatment for wear resistance and fatigue durability.

• Seals: Fluororubber (FKM) or polyurethane (PU) to withstand high-pressure/high-temperature hydraulic fluids.

• Design Features:

• Double-Acting Piston: Alternates hydraulic pressure on both sides to enable bidirectional motor rotation.

• Precision Machining: Piston-to-cylinder clearance maintained at 0.01–0.03 mm to minimize leakage and maximize volumetric efficiency.

• Surface Treatment: Hard chrome plating or DLC (Diamond-Like Carbon) coating to reduce friction and extend service life.

3. Key Performance Attributes

• Efficient Power Transmission:

• Collaborates with the swashplate to convert hydraulic energy into rotational motion with >90% efficiency.

• Impact Resistance:

• Withstands high-frequency shock loads (e.g., soil reaction forces during excavation).

• Leak-Free Operation:

• Composite seals (O-ring + backup ring) prevent high-pressure oil leakage, ensuring stable torque output.

4. Common Failures & Maintenance

• Failure Modes:

• Piston Seizure: Caused by contaminated hydraulic oil scarring the cylinder bore.

• Leakage: Resulting from seal degradation or improper assembly.

• Wear: Long-term high-pressure operation leads to piston diameter wear beyond tolerance.

• Maintenance Recommendations:

• Replace hydraulic oil and filters every 500 hours; maintain oil cleanliness (NAS 6 or better).

• Regularly inspect piston stroke smoothness; disassemble for inspection if abnormalities occur.

• Avoid cold starts (high oil viscosity accelerates wear).
