Product Specifications

For Komatsu D60(141-30-00581,141-30-00585,KM117) dozer track rollers, you’ll need durable, high-quality rollers designed to handle the constant stress of pushing, grading, and excavation. Track rollers (also called bottom rollers) support the weight of the dozer and guide the track chain, making them critical for smooth operation and undercarriage longevity—especially in harsh conditions like mining, construction, or forestry.

Key Features of Komatsu D60 Track Rollers

1. Material & Construction:

   • Forged or high-carbon steel (for heavy-duty applications).

   • Hardened outer shells for wear resistance.

   • Sealed & lubricated bearings (prevents dirt/debris ingress).

2. Types of Rollers:

   • Single-flange rollers (standard for most dozers).

   • Double-flange rollers (extra stability for high-stress use).

   • Rebuilt/remanufactured rollers (cost-effective alternative).

3. Compatibility:

   • Must match Komatsu D60 undercarriage specs (older models may differ).

   • Check shaft size, bolt pattern, and roller width before purchasing.

Maintenance Tips for Dozer Track Rollers

✔ Inspect regularly for wear, cracks, or bearing failure.
✔ Keep seals intact (contamination causes premature failure).
✔ Maintain proper track tension (too tight/loose increases roller wear).
✔ Replace in sets (if one roller is worn, others may be close behind).
