0714410404 , 07144-10404 BUSHING KOMATSU

Premium OEM-Grade Precision Component for Komatsu Heavy Machinery

The 07144-10404 BUSHING KOMATSU (also listed as 0714410404 BUSHING KOMATSU) is a high-precision cylindrical sleeve engineered to handle extreme mechanical stress in Komatsu construction and mining machines. This component serves as a friction-reducing interface between rotating and stationary parts, ensuring smooth motion, accurate alignment, and extended equipment life.

Designed and supplied exclusively by 3GEN Export, this part offers full OEM-level quality with enhanced wear resistance and dimensional accuracy. Each bushing is produced under ISO 9001 standards and delivered globally within 5 working days, ready to install in demanding field environments.

Advanced Engineering for Maximum Durability

Every 07144-10404 BUSHING KOMATSU is manufactured from high-grade Cr-Mo alloy steel, treated through controlled carburizing and induction-hardening processes. The result is a part that withstands the repetitive high-load cycles characteristic of Komatsu excavators, dozers, and wheel loaders.

A dual lubrication groove and precision oil hole system ensure consistent grease distribution, reducing the risk of metal-to-metal contact and overheating. The inner surface is super-finished to sub-micron roughness, maintaining stable performance even under extreme vibration or pressure.

Functional Purpose and Design Features

High-Load Friction Control

The 07144-10404 BUSHING KOMATSU functions as a bearing surface that absorbs radial loads, preventing direct metal contact between pin and housing. The integrated oil grooves distribute lubrication evenly, maintaining an optimal film thickness throughout repetitive cycles.

Structural Stability and Precision

Machined to ISO H7 tolerance, the bushing ensures a tight yet serviceable press-fit within Komatsu housings. Its concentricity minimizes vibration and alignment drift under dynamic conditions, essential for hydraulic performance and chassis stability.

Corrosion and Fatigue Resistance

A phosphate-treated exterior and hardened surface layer defend against rust, abrasive dust, and slurry corrosion commonly encountered on construction and mining sites.

Manufacturing Process

1. Material Selection – Premium alloy bar stock verified for microstructure uniformity.

2. Precision CNC Turning – Maintains micron-level roundness and parallelism.

3. Heat Treatment – Multi-stage carburizing + quenching + tempering for balanced hardness.

4. Grinding and Finishing – External and internal surfaces ground to ≤ 0.005 mm tolerance.

5. Quality Inspection – 100 % dimensional and surface finish validation before shipment.

These controlled steps ensure that each 07144-10404 BUSHING KOMATSU meets or exceeds Komatsu’s factory standards for load endurance and alignment precision.

Advantages and Key Benefits

• Superior Wear Resistance extends service life under high-pressure articulation.

• Reduced Friction Loss leads to smoother machine operation.

• Improved Lubrication Flow via engineered grooves and oil ports.

• Perfect Fit for Komatsu Assemblies without modification.

• Easy Press-Fit Installation saves time in field maintenance.

• OEM-Level Reliability validated through fatigue and salt-spray tests.

• Global Availability with rapid 5-day delivery from 3GEN Export.

Installation Instructions

1. Clean the housing and pin assembly thoroughly.

2. Align the oil hole on the 07144-10404 BUSHING KOMATSU with the lubrication channel.

3. Press-fit the bushing evenly using a hydraulic fixture or arbor press.

4. Apply high-pressure grease until flow appears at the exit groove.

5. Rotate the pin to verify smooth motion and clear lubricant distribution.

Regular lubrication intervals (250–300 operating hours) maintain maximum longevity and performance.

Testing & Performance Validation

3GEN Export conducts extensive bench and field tests to qualify each production batch of the 07144-10404 BUSHING KOMATSU. Performance tests include:

• Fatigue testing under 50 000 oscillating load cycles.

• Friction coefficient tracking through progressive heat rise analysis.

• Corrosion exposure exceeding 240 hours in neutral salt spray.

• Impact resilience tests at –30 °C to simulate cold region operation.

These verifications ensure that the bushing delivers long-term stability and consistent performance in real-world conditions.

Applications Across Komatsu Machinery

The 07144-10404 BUSHING KOMATSU serves critical motion points in Komatsu machines, such as:

• Boom Link Assemblies – absorbing tensile and compressive forces during excavation.

• Arm and Stick Joints – ensuring controlled pivoting and pin alignment.

• Hydraulic Cylinder Eyes – facilitating smooth linear motion.

• Track Frames and Roller Supports – resisting mud and shock impact loads.
