The Hot Sale Komatsu PC220-5 Excavator Carrier Roller is a heavy-duty undercarriage component designed to support and guide the upper section of the track chain. As an essential part of the excavator undercarriage system, the carrier roller helps maintain proper track alignment and supports smooth track movement during traveling, excavation, loading, and other demanding operations.

Designed for the Komatsu PC220-5 Excavator, this carrier roller is manufactured from high-strength steel to withstand continuous loads, vibration, impact, and abrasive working conditions. Precision machining helps maintain accurate dimensions and smooth interaction with the track chain, while controlled heat treatment can improve wear resistance and structural durability.

The carrier roller works together with the track chain, track rollers, front idler, and sprocket. Because it continuously supports the upper track assembly, excessive wear can affect track alignment and increase stress on other undercarriage components. Replacing a worn carrier roller at the appropriate time can help maintain stable track movement and reduce unnecessary maintenance.

Public parts references identify 20Y-30-00022 as a carrier roller applicable to the Komatsu PC220-5, with the same reference also listed for PC200-5, PC220-6, PC220LC-5 and several related models. Komatsu service documentation for the PC220-5 also specifically includes the carrier roller within the track-frame and undercarriage system.
