The 152-4130 Track Roller is a single-flange lower roller designed for selected Caterpillar 375 and 375L excavators. As a major undercarriage component, the track roller supports the excavator’s weight and guides the track chain along the crawler frame during travel and working operations.

Caterpillar identifies 152-4130 as a Roller Group and lists compatibility with the 375-A and 375-A L excavators. The published specifications include a tread diameter of approximately 260 mm, a track pitch of 260.4 mm, and a flange diameter of approximately 304 mm.

The roller is positioned between the track chain and track frame, carrying substantial machine loads while helping maintain correct track movement. A worn or damaged bottom roller can contribute to uneven track wear, increased resistance during travel, and additional stress on other undercarriage components. Replacing worn rollers as part of regular undercarriage maintenance can help maintain stable track operation.

Aftermarket parts catalogs also cross-reference 152-4130 with several Caterpillar roller numbers, including 109-1215, 137-3369, 143-0367, 149-7110, 185-5065 and 6Y8124, depending on machine configuration and production version.
