23A-70-14220 BUSHING KOMATSU / 23A7014220 BUSHING KOMATSU

The 23A-70-14220 BUSHING KOMATSU (also listed as 23A7014220 BUSHING KOMATSU) is a precision-engineered component designed to reduce friction, distribute loads evenly, and enhance the mechanical stability of Komatsu heavy machinery. Serving as a vital element between shafts and housings, this bushing ensures smooth pivot movement and minimizes wear in joints, arms, and suspension points exposed to constant vibration and impact.

Developed to perform under harsh job-site conditions, the 23A-70-14220 BUSHING KOMATSU combines metallurgical strength with a mirror-finish surface that promotes longer service intervals and higher operational reliability. Whether used in the linkage of a bulldozer, the boom joint of an excavator, or the pivot connection of a loader, it guarantees consistent performance and reduced downtime.

Supplied globally by 3GEN Export, this OEM-quality part is available for worldwide delivery within 5 working daysand built to match Komatsu’s original engineering standards.

Functional Role

Bushings act as the silent protectors within a machine’s joint system. The 23A-70-14220 BUSHING KOMATSU is specifically designed to isolate metal-to-metal contact, ensuring that rotating shafts or pins move freely without seizing or distortion.

Inside Komatsu machines, where immense hydraulic forces and mechanical stresses occur, this bushing absorbs impact energy and distributes it evenly over the contact surface. By doing so, it prevents localized wear, extends pin life, and maintains precise alignment between mating components.

Its superior internal surface finish reduces the friction coefficient, allowing lubricants to form a stable film between the pin and bushing surface—essential for minimizing temperature rise and material fatigue during extended work cycles.

Design & Engineering

Each 23A7014220 BUSHING KOMATSU is the product of advanced CNC machining and high-temperature heat treatment. The inner bore and outer diameter are ground to micrometric tolerances, ensuring tight fits without distortion.

Key design highlights include:

• Hardened alloy-steel composition for maximum strength.

• Precision internal grinding achieving ≤ 0.2 µm surface roughness.

• Optimized wall thickness for even stress distribution.

• Anti-corrosion finishing layer for long-term storage and field use.

• Oil-retaining internal surface that improves lubrication intervals.

These features make the 23A-70-14220 BUSHING KOMATSU ideal for high-impact joints such as track frames, swing arms, and boom pivots where continuous motion and heavy loads meet.

Installation and Maintenance

Proper installation of the 23A7014220 BUSHING KOMATSU is essential to preserve alignment and performance.

Installation Guide

1. Clean and degrease the housing bore.

2. Align the bushing perpendicular to the axis.

3. Press-fit using hydraulic or mechanical equipment.

4. Lubricate the inner bore before pin insertion.

5. Verify rotation clearance within spec limits (0.02–0.05 mm).

Maintenance Tips

• Re-grease every 500–1000 operating hours.

• Check for oval wear or surface grooves.

• Replace in pairs to maintain load balance.

• Store in dry, temperature-controlled conditions.

Following these steps helps prevent premature wear and ensures the bushing performs optimally throughout its lifecycle.
