The Bomag 05815717 External Circlip is a genuine OEM retaining component designed for Bomag BW 120 AD and BW 138 AC tandem rollers, as well as BW 1050 T, BW 850 TR, and BW 85 T trench compactors. As an authentic Bomag part, this circlip is manufactured to the same tolerances and material specifications as the original, ensuring a secure, correctly seated installation every time. This component ships with Bomag's part number 05815717, so you can order with confidence knowing you're receiving the exact part for your machine.
Key Features
- Genuine OEM Retention Integrity — manufactured to Bomag's original material hardness and dimensional tolerances, ensuring the clip seats and retains under the dynamic loads of vibratory compaction equipment
- Drop-In Replacement — matches the groove diameter and wire gauge of the original, snapping directly into position without any modification to the shaft or housing
- Broad Model Coverage — fits BW 120 AD and BW 138 AC tandem rollers, plus BW 1050 T, BW 850 TR, and BW 85 T trench compactors, covering multiple BOMAG equipment families with a single part
- Prevents Shaft and Bearing Migration — a correctly installed external circlip locks rotating or sliding components in their designed axial position, protecting bearings, gears, and housings from wear caused by unwanted movement
- Critical Retention Component — circlip failure can allow shafts or assemblies to shift under load, creating vibration, accelerated wear, and potential drivetrain damage; replacing a worn or sprung clip restores mechanical security immediately
An external circlip is a small but structurally critical fastener that fits into a machined groove on the outside of a shaft or pin, locking adjacent components — such as bearings, pulleys, or drive elements — firmly in their axial position. Without it, these components can migrate along the shaft under vibration and load, leading to misalignment, abnormal wear, or outright component failure. On high-vibration machines like tandem rollers and trench compactors, where drivetrain and drum assemblies operate under sustained stress, keeping every retaining component in sound condition is essential to maintaining safe and consistent compaction performance.
