Bomag Circlip,External | Part 09210800

The Bomag 09210800 External Circlip is a genuine OEM retaining component designed for a broad range of Bomag pavers, rollers, reversible vibratory plates, tampers, trench compactors, recyclers/stabilizers, and walk-behind rollers. Sourced directly from Bomag, this circlip matches the original specification for a dependable drop-in installation with no guesswork on sizing or fitment. Confirmed compatibility includes BF 800 and BF 900 series pavers, BW tandem rollers including the BW 80 AD-5, BW 100 AD-5, BW 120 AD-5, and BW 138 AD-5, single drum rollers such as the BW 219 D-4i and BW 226 DH-4i, reversible vibratory plates including the BPR 25/40, BPR 30/38 D, BPR 40/45 D-2, BPR 50/52 D, BPR 65/52 D-3, and BPR 75/60 D, as well as walk-behind rollers, the BT 30 tamper, trench compactors, and MPH and RS series recyclers/stabilizers. When a retaining circlip wears or snaps, the components it secures can shift, causing accelerated wear or mechanical failure — replacing part number 09210800 promptly keeps the assembly properly located and the machine running as intended.

Key Features

• Genuine OEM Circlip Construction — manufactured to Bomag's original hardness and spring-tension specification, ensuring the circlip seats fully in its groove and holds under dynamic load without creeping or fracturing
• Direct Groove-Fit Replacement — matches the original external-circlip profile exactly, snapping into the machined groove without rework or resizing
• Broad Bomag Fleet Coverage — fits BF-series pavers, BW tandem and single drum rollers, BW walk-behind rollers, BPR and BR reversible vibratory plates, the BT 30 tamper, BW trench compactors, and MPH and RS recyclers/stabilizers, consolidating a single part number across multiple machine families
• Prevents Component Migration — a correctly seated external circlip locks shafts, pins, and bearings in axial position; a cracked or missing circlip allows components to walk out of alignment, causing premature wear on surrounding parts
• Cost-Effective Service Item — replacing this small retaining ring at scheduled service or at first sign of deformation is far less expensive than addressing the secondary damage caused by an unsecured assembly

An external circlip is a sprung-steel retaining ring that fits into a machined groove on the outside of a shaft or pin, preventing axially mounted components such as bearings, gears, or sleeves from sliding off or shifting along the shaft. When the circlip is intact and properly seated, it holds the assembly in precise axial position, transferring loads as designed. If the circlip becomes worn, corroded, or cracked — as can happen during heavy compaction or paving cycles — the components it retains can migrate, leading to accelerated bearing wear, unwanted play in drivetrain assemblies, or complete disengagement of the retained part. Routine inspection and timely replacement of the External Circlip is a low-cost measure that protects far more expensive surrounding components.
