Excavator Undercarriage Track Roller OEM Excavator Spare Parts DF Track Rollers

Track roller is an important part of undercarriage, it has two kinds of welding methods, one is traditional and the other is friction-welding. Friction-welding track roller is better in the wear-resistance and has a longer working lifetime. Roller bodies of traditional track roller are connected by the welding rod, but the friction ones are connected by the friction between rollers' bodies. So the friction-welding roller will be added more raw material to make sure the roller is perfect to the standard size after welding. For the traditional rollers, the welding is done after two processes of machining, so the size of the inner parts is not so precise as friction-welding ones. For the friction-welding ones, after the welding, there is one more precise machining with concentric locating to make sure the conformity of inner size, this means the inner parts are more precise with a higher standard.
