A top roller is an essential component of a tracked vehicle’s undercarriage, such as an excavator or bulldozer. It is located on the upper side of the track system, positioned above the track links. The primary function of the top roller is to support the weight of the vehicle while guiding the track as it moves over the rollers, preventing the track from sagging. Top rollers help distribute the vehicle's weight evenly, reduce friction, and extend the lifespan of the track system. Made from durable materials like steel, they are designed to withstand heavy loads and harsh working conditions.
