Detailed Description
The 20Y-70-34221 BUSHING KOMATSU is a cylindrical bearing sleeve with a flanged rim that facilitates better alignment and load distribution during articulation. Precision-machined to strict OEM tolerances, this bushing is built from high-strength steel alloy that undergoes special heat-treatment and surface hardening processes. These enhancements provide exceptional wear resistance, superior mechanical strength, and long-lasting performance in aggressive environments.
The flange aids in controlling axial movement and assists in securing the bushing firmly in place, minimizing the risk of displacement during high-impact operations. Additionally, the inner bore is designed with lubrication grooves that ensure effective grease retention, reducing wear and enabling smoother movement between the mating parts such as pins and joints.
Operators working in rugged construction, mining, or forestry environments understand the critical importance of reliability. The 20Y-70-34221 bushing is designed for precisely that—minimizing unplanned downtime while maintaining the articulation integrity of Komatsu machines.

Role in Excavating Systems
Bushings like the 20Y-70-34221 BUSHING KOMATSU play a central role in the joint systems of heavy-duty excavators. Installed between pins and bores of the arm, boom, or bucket, they allow smooth rotational movement while bearing heavy mechanical loads. Over time, due to repetitive movements and environmental exposure, bushings may experience wear. Timely replacement ensures proper alignment, reduces vibrations, and prevents premature damage to adjacent parts such as bores or pins.
Choosing the correct bushing ensures minimal play and maximum machine responsiveness—critical for applications requiring pinpoint digging accuracy or high cycle counts per hour.
Maintenance and Replacement
Routine inspection of bushings is vital for preventing more severe mechanical failures. Here are a few maintenance insights:
• Inspection Interval: Every 500 operating hours or during routine pin & bush service intervals
• Wear Indicator: Excessive play between the bushing and pin, visible scoring or elongation
• Replacement Time: When radial play exceeds 10% of the original clearance or as recommended in the service manual
• Installation Tips: Always lubricate before insertion; use a press-fit method for consistent alignment
Proper maintenance and timely replacement of the 20Y-70-34221 BUSHING KOMATSU ensures maximum uptime and protects the structural integrity of your equipment.
