The guide wheel is an important component in the walking system of tracked construction machinery, such as bulldozers, excavators, and so on. The function of the idler wheel is to guide the movement of the track. Together with the tensioning device, it can maintain a certain degree of tension on the track and alleviate the impact force from the road when moving forward, reducing the vibration of the body. The idler is not only the idler of the track, but also the tensioning wheel in the tensioning device.

The excavator guide wheel is used to guide the track to rotate correctly, preventing it from deviating and deviating from the track. Most excavators also serve as supporting wheels at the same time. This can increase the contact area between the track and the ground, and reduce the ground pressure. The surface of the guide wheel is made into a smooth surface, with a retaining arm ring in the middle serving as a guide, and the ring surfaces on both sides support the rail chain.

The idler is an important component in the walking system of large construction machinery such as excavators. It is installed on the track to guide the track. Its main function is to guide the track to roll correctly, and at the same time, the tensioning device is used to move the idler to adjust the tension of the track. The idler is not only the idler of the track, but also the tensioning wheel in the tensioning device.
