The Kobelco 7055 Track Roller is a heavy-duty aftermarket undercarriage component developed for Kobelco crawler crane applications. Also known as a bottom roller or lower roller, it carries the crawler crane’s weight and guides the track chain along the lower section of the crawler frame.

Xiamen Doozer manufactures replacement track rollers with a strong focus on durability, precision, and stable performance. High-strength steel is used for the roller body, followed by precision machining and controlled heat treatment. These processes help improve the working surface’s wear resistance and provide reliable performance under repeated loading.

The track roller operates together with the track chain, track shoes, front idler, sprocket, and carrier rollers. Because crawler cranes operate under substantial loads, a worn or damaged roller can affect track movement and accelerate wear across the undercarriage. A properly matched Kobelco 7055 track roller helps support stable crawler movement and maintain consistent track alignment.

The reference 24100N2017F3 is listed by aftermarket crawler-crane parts suppliers as a track roller for the Kobelco 7055. Other supplier catalogs identify the 7055 track roller as a sealed lower roller designed for demanding crawler crane applications. Kobelco’s official 7055-3F specification also confirms the use of sealed track rollers for maintenance-free operation.

Xiamen Doozer provides factory-direct aftermarket crawler crane undercarriage parts for distributors, contractors, repair companies, and equipment-parts dealers. Our manufacturing process emphasizes accurate dimensions, strong working surfaces, and dependable replacement performance.

Before ordering, buyers should confirm the machine version, serial number, and original part number because crawler undercarriage configurations may differ between 7055 generations.
