Key Features
- Genuine OEM Retention Integrity — Manufactured to Bomag's original bore-diameter tolerances, this internal circlip delivers the precise spring tension and groove engagement needed to securely retain shafts and assemblies without play or slippage.
- Drop-In Replacement — Matches the original groove dimensions and material hardness, allowing straightforward installation using standard circlip pliers with no rework to the housing or bore.
- Broad Bomag Fleet Coverage — Fits a wide Bomag lineup including BW-series tandem rollers, single drum rollers, the BW 12 R pneumatic tyred roller, and BC 601 RS and BC 601 RB refuse/landfill compactors.
- Secure Component Retention — A correctly seated internal circlip prevents axial movement of bearings, gears, and shafts; a worn or missing circlip allows components to migrate, causing accelerated wear and mechanical failure.
An internal circlip is a spring-steel retaining ring that snaps into a machined groove inside a bore or housing, preventing a shaft, bearing, or gear from moving axially out of position. It acts as a mechanical stop, keeping rotating and reciprocating components properly located so the assembly functions as designed. When an internal circlip becomes worn, corroded, or dislodged, the components it retains can shift under load, leading to uneven wear, noise, vibration, and ultimately premature failure of surrounding parts.
