Undercarriage is the biggest maintenance cost on a tracked excavator — and correct track specification is the biggest variable in how long it lasts. This track roller 6 301.7d is built to OEM pitch and material specification to maximise service life and protect sprockets and rollers.

Why Choose This Track Roller 6 301.7D
– OEM pitch maintained to ±0.2mm tolerance — correct sprocket engagement from new
– High-carbon alloy pin and bush; surface-hardened at the wear interface for maximum service life
– Shoe bolt holes matched to OEM spacing for standard track shoe fitment

Heavy-Duty Construction
This track roller 6 301.7d is manufactured using forged track link for superior fatigue resistance at the pin boss and shoe bolt holes. Induction-hardened rail surface for correct roller and idler contact wear resistance. Sealed and lubricated pin/bush joints reduce re-greasing intervals and extend bushing service life. Designed to withstand vibration, impact loads, and harsh operating environments commonly found in construction, quarry, mining, and earthmoving applications. Precision manufacturing helps ensure correct fitment and long service life.
