Description for part number 278-9540

A double-flange track roller is a component of the undercarriage system. It is designed to evenly distribute the weight of the machine and the load it carries over a larger surface area, reducing ground pressure and minimizing the risk of sinking or getting stuck in soft or uneven ground conditions. It consists of a cylindrical metal body with a central shaft and two flanges, one on each side. The flanges are positioned symmetrically and are slightly larger in diameter than the central body.

Attributes:
Designed to withstand heavy loads.
Designed to resist wear and deformation.
Provide proper alignment and prevent excessive slack.

Applications:
A double-flange track roller allows the equipment to navigate various terrains and work efficiently. It is extensively used in Cat® 227 Tree Harvester, 229, 235, 235B, 235C, 235D, 320 and 322 Excavators, 517, 527 and D5H Skidder, 566, 572R, 578, 583R, 583T, 587R, 587T, PL72, PL83 and PL87 Pipelayer, 924G, 936, 936E, IT18, IT18B, IT28 and IT28B Wheel Loader, 963 and TR35 Powertrain, 963, 963B, 963C, 973, 973B and 973C Track Loader, D5H, D6H, D6R, D7H, D7R, D8, D8L, D8N, D8R, D8T, D9N, D9R, and D9T Track Type Tractor.
