0714410405 , 07144-10405 BUSHING KOMATSU

High-Precision OEM-Grade Component Engineered for Komatsu Heavy Machinery

The 07144-10405 BUSHING KOMATSU (also cataloged as 0714410405 BUSHING KOMATSU) is a premium-grade cylindrical sleeve designed to ensure reliable alignment, smooth rotation, and minimal wear between moving parts in Komatsu construction and mining equipment. It is a critical part of the linkage and joint assemblies that sustain immense loads and continuous mechanical stress.

As an OEM-quality part supplied by 3GEN Export, this bushing is engineered for exact dimensional compatibility with Komatsu machines and built to outperform traditional aftermarket alternatives. It ensures prolonged operational life, reduced maintenance intervals, and consistent performance even in the harshest environments — from high-humidity job sites to abrasive quarry conditions.

Advanced Material Composition and Heat-Treated Strength

Each BUSHING KOMATSU 07144-10405 is crafted from high-tensile alloy steel (typically 42CrMo4 or SCM435)that offers superior yield strength and fatigue resistance. Through precision CNC machining and induction hardening, the bushing achieves a surface hardness of 58–62 HRC, maintaining stability under extreme load conditions.

The outer layer undergoes fine grinding and polishing for micro-smoothness, reducing friction while allowing controlled lubricant flow. An integrated lubrication groove and precision oil hole deliver consistent lubrication to all contact points, minimizing heat build-up and extending service life.

Technical Specifications

Compatible Komatsu Models

The KOMATSU Bushing 07144-10405 is widely used across Komatsu’s construction and mining machine range. It fits multiple models where the bushing supports linkage motion, pin joints, and cylinder pivots.

Commonly Compatible Komatsu Machines:

• Excavators: PC200-7 / PC200-8 / PC210 / PC220 / PC240 / PC300 / PC350 / PC400

• Bulldozers: D65EX / D85EX / D155AX

• Wheel Loaders: WA200 / WA250 / WA320

• Motor Graders: GD555 / GD675

These machines rely on the 07144-10405 KOMATSU BUSHING in high-friction joints such as:

• Boom and arm linkage connections

• Bucket pivots and main pins

• Swing and track frame joints

• Hydraulic cylinder mount points

The precise fit and load tolerance make it an essential part of maintaining Komatsu’s hallmark durability and operational precision.

Functional Importance of the 07144-10405 BUSHING KOMATSU

1. Friction Control and Load Absorption

This bushing minimizes friction between the pin and housing, absorbing shock loads during digging, lifting, and pivoting movements. Its oil groove pattern ensures even grease distribution, preventing dry zones and reducing the risk of metal-on-metal wear.

2. Dimensional Stability Under Pressure

Maintaining perfect roundness and concentricity under dynamic load conditions is vital. The 07144-10405 BUSHING KOMATSU is engineered with high tolerance control, ensuring smooth articulation while avoiding vibration-induced wear and pin deformation.

3. Resistance to Corrosion and Environmental Stress

Working conditions in construction and mining often expose bushings to dust, moisture, and corrosive agents. The phosphate coating on this bushing adds an essential protective layer, resisting oxidation and chemical degradation over long operational periods.

Engineering and Manufacturing Process

Each KOMATSU 0714410405 BUSHING follows a multi-stage production process that ensures optimal mechanical reliability and geometric accuracy:

1. Material Inspection: Certified alloy steel billets are selected after metallurgical testing.

2. CNC Machining: Precision lathing ensures exact internal and external dimensions.

3. Heat Treatment: Induction hardening and tempering balance surface hardness with core ductility.

4. Grinding & Polishing: Both inner and outer surfaces are ground to sub-micron finish tolerances.

5. Lubrication Channel Formation: Oil grooves and holes are cut for consistent grease flow.

6. Surface Coating: Anti-corrosive phosphate coating applied for environmental durability.

7. Quality Control: Every unit is measured for tolerance, roundness, and hardness.

These procedures guarantee the 07144-10405 BUSHING KOMATSU performs reliably across extreme operational conditions.

Technical Advantages

• OEM-Level Fit and Performance: Fully compatible with Komatsu specifications for plug-and-play replacement.

• Superior Wear Life: Hardened and ground surface offers high endurance under oscillating motion.

• Optimized Lubrication Flow: Oil grooves and ports minimize friction, lowering energy loss.

• Reduced Maintenance Downtime: Prolonged service intervals and fewer replacements required.

• High Impact Resistance: Maintains stability under severe shock and cyclic loading.

• Global Availability: 3GEN Export ensures rapid 5-day delivery anywhere in the world.

Installation and Maintenance Guidelines

Installation Steps

1. Preparation: Clean all mounting surfaces and inspect the housing and pin for damage.

2. Alignment: Match the oil hole of the bushing with the lubrication channel in the housing.

3. Press Fit: Use a hydraulic or mechanical press for even insertion — avoid hammering.

4. Lubrication: Inject grease through the fitting until it flows through the exit port.

5. Validation: Rotate the pin to confirm smooth articulation and proper lubricant coverage.

Maintenance Tips

• Re-grease every 250–300 operating hours for optimal performance.

• Inspect for abnormal clearance or vibration after 1000 hours of use.

• Always replace both pin and bushing if excessive wear is found.

Following these recommendations ensures long-term durability and consistent Komatsu performance.

Quality Testing and Endurance Validation

Every KOMATSU BUSHING 0714410405  supplied by 3GEN Export undergoes a comprehensive testing protocol before shipment. These include:
