Product Introduction

Revised description of Komatsu bushing 6246-71-3190

1. General description

The Komatsu 6246-71-3190 bushing is a genuine factory part designed and manufactured by Komatsu Corporation to company quality and manufacturing standards. As a key element of the chassis and articulated part of Komatsu special equipment, it is responsible for the stability and durability of moving joints, is adapted for intensive use in harsh industrial conditions and is indispensable for maintaining the performance of construction, quarry and other heavy equipment.

2. Specifications

2.1 Material and strength properties

The part is made from a specialized high-strength alloy that combines increased resistance to abrasive wear and impact loads. The material maintains geometric stability under long-term static and dynamic loads, eliminates plastic deformation, and guarantees the maintenance of performance characteristics under intensive use.

2.2 Geometric accuracy

The 6246-71-3190 bushing is manufactured on precision equipment with all dimensional parameters (diameter, length, wall thickness) controlled according to Komatsu specifications. Its perfect geometry ensures a gap-free fit in mating assemblies, a tight seal with adjacent components, and eliminates runout or play in the connection.

2.3 Resistance to operational factors

The bushing is resistant to adverse environmental conditions, including dust, moisture, temperature fluctuations, and contact with operating fluids (oils, lubricants, and coolants). This allows the part to maintain its properties without losing efficiency on construction sites, quarries, agricultural fields, and other challenging conditions.

3. Application in Komatsu equipment

Bushing with part number 6246-71-3190 is designed for installation in the hinge assemblies of a wide range of Komatsu special equipment models, including excavators, bulldozers, and road construction equipment. Main applications:

• Hinges of the rotating mechanism of the working element (excavator bucket);

• Extension and lifting units of lever mechanisms;

• Other moving joints requiring smooth rotation and uniform load distribution.

The part performs two main functions: it ensures smooth interaction of moving elements and protects the axles, hinges, and adjacent components from premature wear, thereby extending the overall service life of the equipment.

4. Key benefits

4.1 Increased reliability

Strict quality control at all stages of production, from raw material selection to final inspection, guarantees reliable operation of the bushing under intensive use. The absence of unexpected failures and breakdowns minimizes equipment downtime and improves overall fleet productivity.

4.2 Long service life and cost effectiveness

The material's high wear resistance significantly increases the interval between repairs and reduces the frequency of component replacement. This reduces operating costs, spare parts, and maintenance expenses.
