The Bomag 31780453 Retainer Ring is a genuine OEM component designed for BW-series tandem rollers, single drum rollers, and pneumatic tyred rollers, including the BW 184 AD, BW 180 AD, BW 177 D-3, BW 177 DH-3, BW 177 PDH-3, BW 178 D-3, BW 212 D-3, BW 213 D-3, BW 213 PDH-3, BW 24 R, C 850 C, and C 560 B. Sourced directly from Bomag, this retainer ring carries the same part number 31780453 used in the original assembly, so there is no guesswork on compatibility. This part installs as a direct replacement, maintaining the mechanical integrity of the assembly it secures across the full range of compatible machines.
Key Features
- Genuine OEM Retention Geometry — manufactured to the exact dimensional tolerances Bomag specifies for this retainer ring, ensuring the secured component seats and holds correctly without slipping or deforming under load.
- Direct Drop-In Replacement — matches the original retainer ring profile and seating groove dimensions for a straightforward installation on compatible Bomag roller assemblies.
- Broad Roller Coverage — fits BW-series tandem rollers including the BW 184 AD and BW 180 AD, single drum rollers including the BW 177 D-3, BW 213 D-3, and BW 213 PDH-3, and pneumatic tyred rollers including the BW 24 R and C 560 B.
- Sustained Clamping Integrity — a properly functioning retainer ring keeps rotating or reciprocating components correctly positioned; a worn or missing ring allows unwanted axial movement that accelerates wear across surrounding parts.
- Verified Bomag Part Number — ordered and supplied under part number 31780453, matching the Bomag OEM catalog reference for every machine in the fitment list.
A retainer ring — also known as a circlip or snap ring — is a fastening device that seats into a machined groove on a shaft or inside a bore, locking a component such as a bearing, gear, or drum assembly into its correct axial position. It prevents the secured part from sliding or walking out of place during operation, which is critical on compaction equipment subject to continuous vibration and dynamic loading. When a retainer ring becomes worn, corroded, or loses its spring tension, the component it holds can shift, causing accelerated wear, noise, and eventual mechanical failure in the surrounding assembly.
