Hitachi EX60-5 Excavator Carrier Roller For Heavy Duty Wheels

Hitachi EX60-5 Carrier Roller Product Specifications

Product Description
The carrier roller (also called track roller) is a critical component of the undercarriage system in crawler excavators. It supports the machine’s weight, guides the track chain, and reduces friction between the track and the frame. Designed for the Hitachi EX60-5 compact hydraulic excavator, this roller must provide high wear resistance, load-bearing capacity, and effective sealing to withstand diverse working conditions.

Key Features
1,Superior Wear Resistance

High-frequency hardened roller surface (HRC 55-62) minimizes wear from track shoe friction.

2,Advanced Sealing

Dual-lip seal + O-ring prevents contamination and grease leakage (critical for longevity).

3,Heavy-Duty Load Capacity

Reinforced structure distributes load evenly, handling machine weight and dynamic shocks.

4,Low-Friction Operation

Precision bearings and high-quality grease ensure smooth movement and reduce energy loss.

5,Exact OEM Fit

Manufactured to Hitachi’s original specifications for seamless installation.

Recommended Applications

• 1,Municipal Work: Road repairs, pipeline installation (low-impact conditions).

• 2,Agriculture/Farming: Trenching, land leveling (soft/muddy terrain).

• 3,Construction Sites: Gravel, backfilling (moderate abrasion environments).

• 4,Rental Fleets: High-usage scenarios requiring durable components.

• Maintenance & Troubleshooting

1,Routine Checks

• Inspect for cracks, abnormal wear, or oil leaks (seal failure).
• Rotate roller manually to detect bearing roughness.

2,Common Failures

• Track Misalignment: Uneven roller wear or improper installation.
• Noise: Contaminated bearings or insufficient lubrication.
• Grease Leakage: Seal damage—replace immediately.

Critical Notes

• Never operate with damaged rollers—risk of track derailment or undercarriage damage.
• In muddy/abrasive environments, inspect every 50 service hours.

For exact part numbers, provide:

• Machine serial number (S/N plate near cab rear).
• Photos of old rollers (show dimensions/part numbers).

Replacement Tips:

• Replace in pairs (left/right) to avoid uneven track wear.
• Tighten bolts to specified torque (refer to service manual).

Conclusion

The Hitachi EX60-5 carrier roller directly impacts machine stability and operating costs. Prioritize sealing quality and material hardness when selecting replacements. Proper maintenance extends service life (typically 3,000–5,000 hours).
