Komatsu PC200-5 Track Roller OEM Replacement - Undercarriage Bottom Rollers Factory Direct
1. Appliion
Undercarriage systems – comprising sprockets, rollers, and track pads – critically impact excavator performance. These core components (sprockets, idlers, track rollers, carrier rollers, track pads) directly affect operational efficiency, with their combined weight and production costs accounting for 25% of total excavator manufacturing expenses
2. Differences between Friction-welding and Traditional Type
* Friction-welded track rollers exhibit superior wear resistance and extended service life due to their metallurgically bonded interfaces, which maintain structural integrity under sustained operational stresses.
* 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.
