Material Composition and Manufacturing

The 23A-27-11620 BUSHING KOMATSU is produced using induction-hardened alloy steel, selected for its high compressive strength, fatigue resistance, and durability in abrasive environments. Every stage of production, from forging to grinding, adheres to strict OEM tolerances.

Manufacturing Process Overview:

1. Alloy Selection: High-carbon chromium-molybdenum steel chosen for wear resistance.

2. Forging: The material is forged under controlled heat for uniform grain structure.

3. Machining: CNC machining ensures precision in both internal and external diameters.

4. Heat Treatment: Induction hardening increases surface hardness while maintaining a tough, flexible core.

5. Grinding: Mirror-smooth finish achieved through multi-stage grinding for optimal fit and lubrication flow.

6. Quality Inspection: Each bushing is measured to ±0.01 mm accuracy for diameter and roundness.

Technical Highlights:

• Material: Alloy steel (Cr-Mo or SAE 4140 equivalent)

• Surface Hardness: 58–62 HRC

• Core Toughness: Maintained through tempered core design

• Coating: Phosphate anti-corrosion treatment

• Tolerance: ±0.01 mm

• Lubrication Retention: Internal oil grooves for consistent grease film

• Weight: 0.16 kg

This combination of mechanical strength and refined surface precision makes the 23A2711620 BUSHING KOMATSUone of the most reliable pivot bushings for Komatsu machines operating under heavy load conditions.

Installation and Maintenance Guidelines

Proper installation of the 23A2711620 BUSHING KOMATSU ensures long-term performance and minimal maintenance.

Installation Procedure:

1. Surface Cleaning: Remove rust, grease, or debris from the bore before inserting the bushing.

2. Lubrication: Apply assembly grease to both outer and inner surfaces for smooth fitting.

3. Press Fit: Use a hydraulic press to install the bushing evenly—avoid hammering to prevent distortion.

4. Alignment Check: Ensure the bushing is centered and seated fully flush within the housing.

5. Final Inspection: Rotate the mating pin by hand to verify smooth, friction-free movement.

Maintenance Recommendations:

• Grease joints at regular intervals to maintain consistent lubrication.

• Check for wear every 500 operational hours.

• Replace both pin and bushing simultaneously to maintain proper tolerance.

• Avoid operating equipment with worn bushings, as this can damage housings and increase maintenance costs.

Following these best practices ensures the 23A-27-11620 BUSHING KOMATSU functions flawlessly for thousands of operational cycles.
