1953003040 track carrier roller assembly

The Komatsu D375 (A-2, A-3, A-5, A-6) is a 70-ton class bulldozer designed for extreme ripping and bulk earthmoving. At this scale, the Carrier Roller (Top Roller) does more than just hold up the track; it maintains the harmonic stability of the entire undercarriage. Our D375 series carrier rollers are engineered with reinforced dual-cone seals and deep-case hardening to survive the massive centrifugal forces and abrasive dust of mining environments.
