Detailed Description

Bushings are indispensable in ensuring the operational longevity of heavy machinery. The 208-70-72170 BUSHING KOMATSU plays a fundamental role in maintaining structural integrity between moving metal components. It minimizes direct metal-to-metal contact, distributes loads evenly, and reduces surface fatigue — ultimately preventing early component failure.

This particular bushing features a flanged design that provides extra support, ensuring a tight seating within the bore and preventing axial movement. The internal spiral grease grooves allow for consistent lubrication even during continuous high-load use, enhancing the component’s durability while lowering maintenance frequency.

Built from a high-carbon alloy steel, this bushing undergoes a heat treatment process to enhance hardness and wear resistance without compromising toughness. Whether you are working in mining, earthmoving, or demolition environments, this bushing withstands shock, vibration, and dirt intrusion — conditions that frequently cause premature wear in lower-grade alternatives.

Key Features

• OEM-quality fit and performance: Perfect alignment with KOMATSU excavator models

• Extended service life: Heat-treated alloy steel resists wear and corrosion

• Reduced operational downtime: Supports longer maintenance intervals

• Excellent load distribution: Withstands radial and axial stress effectively

• Smooth articulation: Supports optimal bucket and boom movement

• Easy lubrication: Spiral grooves ensure uniform grease coverage during operation

• Flanged base: Locks the bushing in place and prevents axial slip

Role in Excavating Systems

The 208-70-72170 BUSHING KOMATSU is strategically positioned in the pivot joints of boom arms, link rods, or bucket connections. In excavators, where these joints experience frequent load changes, vibrations, and motion, bushings absorb wear that would otherwise damage the main structure. By acting as a buffer, this bushing not only protects adjoining parts but also supports high-precision movements crucial for digging, lifting, and grading.

Maintenance and Replacement

Timely replacement of the 208-70-72170 BUSHING KOMATSU ensures machinery runs efficiently and safely. A worn-out bushing may cause misalignment, poor articulation, or unexpected failure of pins and shafts. It is advisable to inspect bushings:

• After every 1000–2000 operating hours (depending on load intensity)

• When unusual vibrations or play is noticed at bucket joints

• If hydraulic movement becomes jerky or unresponsive

Proper lubrication is essential to maximize performance. This bushing is compatible with standard lithium-based greases used in KOMATSU systems. Always follow KOMATSU maintenance schedules or consult with your technical team or 3GEN Export’s support staff for optimal care practices.
