Track Roller

A track roller, also known as a bottom roller, is a component of a track-type machine that supports and guides the tracks. Track-type machines, such as bulldozers, excavators, and crawler cranes, use a track system instead of wheels for movement over uneven terrain. The track rollers play a critical role in supporting the weight of the machine and guiding the track along the undercarriage.Track rollers are typically made of steel or a similar durable material and are mounted on a shaft that is attached to the undercarriage of the machine. The rollers are designed to rotate freely on the shaft, which reduces friction between the track and the undercarriage, and also helps to distribute the weight of the machine evenly over the track.
