0714310304 , 07143-10304 BUSHING KOMATSU

Heavy-Duty Precision Component for Komatsu Construction and Mining Machinery

The 0714310304 BUSHING KOMATSU is a precision-machined cylindrical bearing designed to reduce friction, absorb impact, and ensure long-term alignment between moving components in Komatsu heavy equipment. Manufactured with high-grade alloy steel and surface-hardened to withstand the severe working conditions of excavators, bulldozers, and loaders, this bushing is a cornerstone of Komatsu’s structural integrity and smooth operation.

As an OEM-grade product supplied exclusively by 3GEN Export, it meets rigorous dimensional tolerances, metallurgical hardness, and performance standards, providing operators the same reliability expected from factory-installed parts—with the added advantage of worldwide delivery in 5 working days.

Engineered for Durability and Accuracy

Each 07143-10304 BUSHING KOMATSU is produced using advanced forging, precision turning, and induction-hardening techniques. The inner bore achieves mirror-finish accuracy (Ra < 0.2 µm), minimizing friction and wear during oscillation and rotation.

The outer surface is ground to ISO fit H7 tolerance, ensuring a press-fit connection within Komatsu housings or pivot arms. Its metallurgical balance—tough core, hardened surface—delivers superior shock absorption and prevents micro-cracks even under high radial loads.

Technical Specifications

Compatible Komatsu Models

The 07143-10304 BUSHING KOMATSU is compatible with a wide range of mid-size and large Komatsu machines. Common applications include boom and stick pivots, bucket linkage assemblies, and hydraulic cylinder joints.

Used In These Komatsu Models:

• PC200-6 / PC200-7 / PC200-8 Hydraulic Excavators

• PC210 / PC220 / PC240 Series Excavators

• PC300-7 / PC300-8 and PC350 Series

• D65EX / D85EX / D155AX Bulldozers

• WA200 / WA250 / WA320 Wheel Loaders

• GD555 / GD675 Motor Graders

This versatility allows the same bushing to function seamlessly across multiple Komatsu platforms—making inventory management easier for maintenance teams and repair centers worldwide.

The Role of 07143-10304 BUSHING KOMATSU in Machine Assemblies

A bushing acts as the sacrificial, wear-resistant interface between a rotating pin and its housing. Without it, metal-to-metal contact would rapidly degrade precision joints. The 07143-10304 BUSHING KOMATSU ensures:

• Reduced Friction: The inner bore’s fine finish creates a consistent lubricating film, minimizing resistance.

• Shock Absorption: It cushions impact loads during digging, grading, or lifting operations.

• Alignment Retention: Maintains perfect geometry between structural arms and cylinders.

• Extended Component Life: Prevents wear on costly housings and pins.

Manufacturing Excellence

1. Raw-Material Selection

Only certified alloy bars (Cr-Mo series) are used, providing superior fatigue strength and machinability.

2. Precision Machining

CNC turning and internal grinding achieve dimensional repeatability within ± 0.01 mm.

3. Heat Treatment

A two-stage process—carburizing followed by induction hardening—produces a wear-resistant surface layer while preserving core ductility.

4. Quality Control

Each 07143-10304 BUSHING KOMATSU undergoes 100 % inspection for dimensions, surface hardness, and roundness before shipment.

Advantages and Benefits

• Exceptional Wear Resistance under continuous load.

• High Load-Bearing Capacity for hydraulic pivot points.

• Easy Installation due to precision sizing.

• Longer Maintenance Intervals reduce downtime.

• Corrosion Resistance with protective surface finish.

• Cost-Effective Solution compared to replacing entire assemblies.

Installation Guidelines

1. Clean both housing bore and shaft pin thoroughly.

2. Align the 07143-10304 BUSHING KOMATSU with the housing axis.

3. Press-fit evenly using a hydraulic tool or fixture.

4. Apply lubricant through grease fittings or internal channels.

5. Recheck clearance and rotational smoothness after assembly.

Maintenance Tip: Lubricate every 250–300 operating hours to maintain the oil film and minimize metal contact.

Applications in Heavy-Machinery Systems

• Boom and Arm Connections on excavators

• Track Roller Frames on dozers

• Steering Knuckle Joints on wheel loaders

• Hydraulic Cylinder Mounts across Komatsu equipment

In each case, the 07143-10304 BUSHING KOMATSU acts as a critical interface absorbing torsional stress and vibration, preserving both structural and hydraulic efficiency.

Testing and Validation

Every bushing manufactured under 3GEN Export’s OEM program is tested to simulate real Komatsu operating conditions:

• 50 000 cycle fatigue load tests under axial pressure.

• Salt spray corrosion testing exceeding 240 hours.

• Dimensional stability under thermal expansion.

• Lubrication retention and film adhesion analysis.

Results confirm that the 07143-10304 BUSHING KOMATSU offers 50 % longer service life than typical aftermarket alternatives.
