Key Features
- Genuine OEM Retention Integrity — manufactured to Bomag's original dimensional and material specifications, ensuring the ring seats and holds exactly as intended for secure component retention
- Drop-In Replacement — engineered to match the original retainer ring profile, allowing straightforward installation with no machining or modification to mating components
- Broad BW-Series Coverage — fits tandem rollers including BW 100 AD-5, BW 120 AD-5, BW 138 AD-5, BW 154 AP-4, BW 174 AP-4, BW 190 AD-5, and BW 202 AD-5; single drum rollers including BW 145 DH-5, BW 177 DH-5, and BW 124 DH-5; and pneumatic tyred rollers BW 27 RH-4i and BW 11 RH-5
- Sustained Component Security — a correctly seated retainer ring prevents axial movement of bearings, shafts, and housings; a worn or missing ring can lead to component migration, accelerated wear, and unplanned assembly failure
- Verified Part Number — ordering as Bomag part number 05821381 eliminates compatibility guesswork across the many BW-series model variants this ring serves
A retainer ring — also known as a snap ring or circlip — is a fastening device that sits in a machined groove on a shaft or inside a bore to hold rotating or sliding components in their correct axial position. In Bomag roller assemblies, retainer rings are commonly used to secure bearings, seals, and other precision components within housings, preventing them from shifting under the vibration and load these machines produce during compaction work. When a retainer ring becomes deformed, fatigued, or dislodged, the components it holds can migrate out of position, causing rapid bearing wear, seal failure, or structural damage to the surrounding assembly.
