- Genuine Wacker Neuson Part — Supplied as an authorized OEM component, carrying the full assurance of Wacker Neuson's parts quality standards for this collar type.
A collar in this application serves as a precision retaining and locating component, holding a shaft, bearing, or rotating element in its correct axial position within the drum or drivetrain assembly. By keeping the mating parts properly seated, it prevents unwanted lateral movement that would otherwise accelerate wear on adjacent bearings and seals. When a collar becomes worn, cracked, or dimensionally out of spec, it allows shaft migration that can lead to uneven drum performance, increased vibration, and secondary damage to surrounding components — making timely replacement an important part of routine roller maintenance.
