The Wacker Neuson 5100012950 is a genuine OEM Locking Ring designed for the RD24, RD27, RD28, RD40, and RD45 series tandem rollers and the RC70 and RC110 single-drum soil compactors. As a factory-sourced component, this Locking Ring is manufactured to the exact specifications of the original part it replaces, ensuring a consistent, correct installation every time. Fitment spans a broad range of configurations across the RD and RC families, including open-ROPS, cab, DPF, combination, and electric variants. Confirm your model number against the compatibility list before ordering to ensure this is the right part for your machine.
Key Features
- Genuine OEM Retention Integrity — Sourced directly from Wacker Neuson, this Locking Ring meets the original dimensional and material tolerances required to hold its mating components securely under sustained vibration and load cycling.
- Drop-In Installation — Engineered to the same profile as the original, this ring seats and locks into position without modification, maintaining the correct axial retention geometry on installation.
- Broad RD and RC Family Coverage — Compatible with RD24, RD27, RD28, RD40, and RD45 tandem rollers across multiple configurations, as well as RC70 and RC110 single-drum soil compactors including cab, ROPS, DPF, and electric variants.
- Sustained Performance Under Vibration — A correctly seated locking ring prevents axial drift and component loosening during high-frequency compaction cycles. A worn or failed ring can allow critical assemblies to shift, leading to accelerated wear of adjacent components.
A locking ring is a retention component used to secure rotating or sliding assemblies — such as bearings, shafts, or drum-drive elements — against axial movement during operation. On compaction equipment like tandem rollers and single-drum soil compactors, these machines generate continuous vibration loads, and the locking ring plays a key role in keeping internal assemblies properly positioned. When a locking ring wears, deforms, or fails, the components it retains can shift out of alignment, causing uneven wear, noise, or more serious mechanical damage to surrounding parts if not addressed promptly.
