E330 Cat Undercarriage Parts SF Track Rollers Replacement

Asymmetrical single flange structure to guide the track chain and prevent lateral slippage, specifically engineered for the E330’s undercarriage geometry.

Flange edge is precision-machined and rounded to minimize wear on track links.

Double floating seals (high-chromium alloy, HRC 65–70) to prevent oil leakage and block contaminants (mud, dust, water) in harsh working conditions.

FKM O-rings with temperature resistance (-20°C to 200°C) for reliable sealing in extreme temperatures.

Pre-filled with high-performance lithium complex grease (NLGI 2) for lifetime lubrication, eliminating the need for regular maintenance.
