EX55 HITACHI Bottom Track Rollers OEM Undercarriage Parts for Construction Machine

1. What is a roller?

The roller, a crucial component of the belt conveyor, serves to support both the conveyor belt and the weight of the conveyed material. Representing 35% of the overall cost of the belt conveyor, it generates over 70% of the resistance, highlighting the significance of roller quality. There exist two welding techniques: the traditional method and friction welding, with the latter yielding superior friction-welded track rollers.

2. 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 rollers 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 to 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 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 loing to make sure the conformity of inner size, this means the inner parts are more precise with a higher standard.
