The supporting disc is a structural component within the drum or drive assembly of the roller, providing a stable bearing surface that distributes rotational or compressive loads evenly across mating parts. It keeps critical components correctly aligned during operation, which is essential for smooth drum rotation and consistent compaction output. When a supporting disc wears or fails, it can cause uneven load transfer, accelerated wear on adjacent components, and vibration or noise that signals deeper mechanical issues if left unaddressed.
