The Komatsu 195-30-01433 Idler Assembly (Front Idler) is a genuine OEM-specification undercarriage component designed for the Komatsu D375A-6R and D375A-8 mining dozers. This idler is a critical component that guides the track chain and maintains proper track tension at the front of the undercarriage.
The D375A-6R and D375A-8 are large mining dozers used in surface mining, heavy dozing, overburden removal, and land reclamation applications. The idler features a precision-machined tread surface with induction hardening for maximum wear resistance. Advanced floating seals prevent contamination and retain lubrication, ensuring extended service life in severe mining conditions.
