Product Description
Carrier Roller also called top roller or upper roller which is an important undercarriage part for crawler excavator or bulldozer. They are in a close contact with the ground walking undercarriage, therefore the quality of carrier roller has great influence on the performance of the excavator and bulldozer.
The carrier roller of the excavator is used to hold the track to prevent the track from sagging too much, so as to reduce the vibration of the track in motion and prevent the track from sliding sideways. Compared with the supporting bottom roller, the supporting roller bears less force, is less eroded by dirt in work, and the working conditions are better than the supporting roller. Therefore, the structure of the supporting roller is simpler and the size is smaller.
In order to reduce the friction loss between top roller and track group, the quantity is not too many, usually used 1pc or 2pcs. The position of the top roller should be favorable for the disengage from the engagement of the driving sprocket, and slide smoothly through the top track and maintain the tension of the track chain. When used 2pcs, the rear one should be close to the driving sprocket.
