carrier roller

Carrier rollers are part of the track system of heavy tracked construction equipment like excavators and bulldozers.
They support the track from the top side and are used in conjunction with the track chain to provide a smooth operation.
How it works:
Structure: Small cylindrical rollers that are mounted to the frame of the machine above the tracks.
Operation: As the track chain revolves around the undercarriage, the carrier rollers bear the weight of the machine, reduce the level of wear on other components, and assist in track alignment. Carrier roller is a component in the undercarriage of tracked construction machinery. It supports and guides the upper section of the track chain, distributes the machine’s weight evenly, and allows for smooth rolling movement.
