Engineering Excellence and Construction

Material Composition

The 23B-27-11330 PIN KOMATSU is manufactured using high-strength alloy steel known for its combination of toughness, fatigue resistance, and excellent machinability. The composition is typically equivalent to AISI 4140 (42CrMo4), a chromium-molybdenum steel that offers a fine balance between hardness and elasticity.

Material Details:

• Base Alloy: 42CrMo4 / AISI 4140 hardened steel

• Surface Treatment: Induction-hardened and tempered to achieve superior surface hardness

• Hardness Level: 55–60 HRC on the outer surface, 30–35 HRC at the core

• Coating: Phosphate or anti-corrosive oil film for oxidation protection

• Finish: Ground and polished to mirror smoothness for minimal friction during operation

This careful metallurgical composition allows the 23B2711330 PIN KOMATSU to withstand repetitive shock loads, while its internal ductility prevents brittle failure even under torsional stress.

Dimensional Characteristics

• Total Length: ≈ 165 mm

• Diameter: ≈ 42 mm

• Thread Pitch: M16 × 2.0 mm (standard fine thread)

• Surface Roughness: ≤ 0.4 µm

• Weight: ≈ 2.44 kg

Every 23B-27-11330 PIN KOMATSU is CNC machined with ultra-low tolerance deviation (±0.005 mm) to ensure perfect fitment within Komatsu boom, arm, and bucket assemblies.

Function and Mechanical Role

The 23B-27-11330 PIN KOMATSU acts as a mechanical hinge and load distributor in Komatsu’s heavy equipment linkage systems. It connects structural components that must pivot freely while maintaining precise alignment, such as:

• Arm-to-boom joints

• Boom-to-bucket couplings

• Tilt and lift cylinder linkages

Its fundamental purpose is to sustain rotational motion under compression and shear, ensuring that all parts move smoothly within hydraulic motion sequences.

Mechanical Functions:

• Transfers hydraulic cylinder force to the working tool (bucket or blade)

• Maintains geometric stability of moving joints

• Minimizes side load stress on bushings

• Ensures accurate pivot alignment during load cycles

• Absorbs impact during digging, lifting, or grading operations

Without this precision-engineered pin, the machine’s articulation system would experience misalignment, excessive vibration, and premature wear, causing loss of efficiency and possible component failure.

Key Performance Features

• High Strength: Built to endure axial and radial forces during demanding excavation cycles.

• Surface Hardness: Induction-hardened to resist wear and abrasion.

• Perfect Geometry: Maintains tight tolerance for consistent rotation without play.

• Anti-Corrosive Coating: Phosphate treatment for long-lasting rust protection.

• Friction Reduction: Polished surface minimizes wear on mating bushings.

• Threaded Design: Securely locks into housing with precision thread pitch.

• Heat Resistance: Performs consistently in high-temperature hydraulic environments.

• Extended Lifespan: Exceeds 10,000 operational hours under normal duty conditions.

Every 23B-27-11330 PIN KOMATSU from 3GEN Export is tested for concentricity, micro-cracks, and surface uniformity using advanced non-destructive inspection methods.

Compatible Komatsu Models

The 23B-27-11330 PIN KOMATSU is used in a variety of Komatsu construction and mining machines. It is typically installed in boom, arm, and bucket linkages or hydraulic pivot joints.
