Komatsu Bearing 17A-15-39310 – Heavy-Duty Rotating Support for Large Crawler Dozers
The Komatsu Bearing (Part No. 17A-15-39310) is a precision-machined rotary support component engineered for select large Komatsu crawler dozers. As a critical part of the undercarriage or drivetrain system, this bearing ensures smooth rotation, reduces friction, and supports heavy radial and axial loads — directly impacting track mobility, blade operation, and overall machine stability.
Manufactured to Komatsu's original equipment specifications, this genuine-grade bearing delivers consistent performance, wear resistance, and long service life under extreme pushing, ripping, and dozing conditions. Whether you are performing scheduled undercarriage maintenance, rebuilding a final drive, or replacing worn rotating components, choosing the 17A-15-39310 guarantees a perfect fit and factory-correct performance.
