3.Differences between Friction-welding and Traditional Type

• Friction-welding track roller is better in the wear-resistance and has a longer working lifetime.
• Consumption of raw material: the 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.
• Inner parts: For the traditional rollers, the welding is done after two processes of maching,so the size of the inner parts are not so precise as friction-welding ones. For the fricion-welding ones, after the weilding, there is one more precise maching with concentric loing to make sure the conformity of inner size,this means the inner parts are more precise with higher standard.
