2. Differences between Friction-welding and Traditional Type

* Friction-welded track rollers show enhanced wear resistance and longer lifespan.
* Material: Unlike conventional rollers joined with filler, friction-welded ones rely on body-to-body contact, requiring extra material to maintain desired dimensions post-weld.
* Precision: Traditional rollers are welded after two machining stages, leading to less precise internal dimensions.Friction-welded rollers undergo additional precise machining post-weld for concentric alignment, ensuring higher precision and quality.
