The E320 Top Roller is a precision-engineered component designed for Caterpillar 32-ton series excavators. This critical wear part in the undercarriage system supports the upper run of the rubber track, reducing friction between the track and machine frame to ensure smooth operation during heavy-duty tasks.
Engineered for durability and excellent load-bearing capacity, this top roller withstands significant vertical and horizontal forces, preventing track slippage, uneven wear, and costly downtime in demanding construction environments.
- High-grade Material Selection: Premium materials for maximum durability
- Outer Race/Shell: High-carbon chromium bearing steel (SUJ2) for superior hardness and wear resistance
- Inner Roller/Spindle: Alloy steel (SCM440) engineered to withstand significant radial and axial loads
- Seals & Lubrication: Nitrile rubber (NBR) seals with lithium-based grease for long-term lubrication
- Quality Assurance: Thorough inspection of all materials for chemical composition and mechanical properties
