Track chain wear accelerates once pin and bush wear allows pitch elongation — an elongated chain jumps sprocket teeth and wears the sprocket rapidly. This track roller e330d is manufactured to OEM pitch, pin diameter, and bush specification to restore correct drive engagement and extend undercarriage service life.

Why Choose This TRACK ROLLER E330D
– OEM-matched pitch for correct sprocket tooth engagement at rated chain speed
– Pin and bush diameters held to OEM tolerance — correct joint clearance from new
– Shoe bolt hole pattern matched to OEM for direct track shoe attachment

Heavy-Duty Construction
This track roller e330d is manufactured using high-carbon alloy steel pin and bush; surface-hardened to resist wear at the pin/bush interface. Track link forged for correct grain structure. Sealed and lubricated pin/bush joints available for extended service intervals in abrasive conditions. 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.

Applications
