The Bomag 9214000 External Circlip is a genuine OEM retaining component designed for a broad range of Bomag cold milling machines, tandem rollers, single drum rollers, walk-behind rollers, and recycler/stabilizers. This circlip delivers an exact OEM fit across multiple Bomag equipment families, including BM-series cold milling machines, BW-series rollers, and MPH-series recyclers. As a genuine Bomag part, it is manufactured to the same specification as the original, ensuring correct retention and dimensional accuracy right out of the box. Compatible machines span models such as the BM2000/50, BM1000/30-2, BW 164 AD, BW 202 AD-2, BW 177 DH-4, MPH 122, MPH 600, and RS 650, among others.
Key Features
- Genuine OEM Retention Spec — manufactured to Bomag's original groove-diameter and spring-temper tolerances, so this circlip seats and holds exactly as the original did
- Direct Drop-In Installation — matches the OEM groove dimensions on all listed Bomag shaft and bore applications, requiring no filing, bending, or modification
- Broad Cross-Family Coverage — fits BM cold milling machines (including BM1000/30-2, BM1200/30-2, BM1300/30-2, BM2000/50, BM2000/65 Stage V, and BM2200/65 Stage V), BW tandem rollers, BW single drum rollers, BW walk-behind rollers, MPH and RS recyclers/stabilizers
- Secure Axial Retention — a correctly fitted external circlip prevents shaft components from migrating axially under vibration and load; a worn or missing circlip allows bearing, gear, or pulley walk that leads to accelerated wear and mechanical failure
- Corrosion-Resistant Construction — hardened spring steel resists the moisture, debris, and vibration cycles common to compaction and milling environments, maintaining clamping force over the full service interval
An external circlip is a precision-formed open ring that snaps into a machined groove on the outside of a shaft or pin, creating a positive mechanical stop that prevents mounted components — such as bearings, pulleys, or gears — from sliding off axially. It works entirely through radial spring tension against the groove walls, so correct material hardness and dimensional accuracy are critical; an undersized or worn circlip will not generate enough retention force and can slip free under load. When a circlip fails or goes missing, the components it retains begin to shift, causing uneven wear, noise, and eventual damage to surrounding assemblies — making prompt replacement with a correctly specified part essential to keeping the drivetrain or accessory system intact.
