Bomag Belleville Spring | Part 09290808

The Bomag 09290808 Belleville Spring is a genuine OEM component designed for a broad range of Bomag BW-series rollers, including BW 75 ADL walk-behind light rollers and an extensive lineup of BW tandem rollers spanning the BW 100, BW 115, BW 120, BW 124, BW 131, BW 135, BW 138, BW 141, BW 151, BW 154, BW 161, BW 170, BW 174, BW 184, BW 190, BW 191, BW 202, BW 203, BW 205, BW 206, and BW 124 D single drum roller. Sourced directly from Bomag, this genuine OEM spring meets the original design tolerances and material specifications of the factory part it replaces. Confirm part number 09290808 against your machine's service documentation to ensure a correct match before ordering.

Key Features

• Genuine OEM Spring Rate Accuracy — manufactured to the exact load-deflection curve specified for this application, ensuring the spring delivers consistent clamping or tensioning force rather than the variable behavior a worn or non-spec spring produces
• Direct Drop-In Replacement — matches the original outside diameter, inside diameter, and thickness of the factory part, so this Belleville spring seats correctly in its stack without shimming or rework
• Wide BW-Series Coverage — fits BW 75 ADL walk-behind light rollers, BW 124 D single drum rollers, and tandem roller variants including the BW 100, BW 120, BW 135, BW 138, BW 141, BW 151, BW 154, BW 161, BW 174, BW 190, BW 191, BW 202, BW 203, BW 206, and additional BW models listed in the compatibility data
• Sustained Clamping Performance — a correctly rated Belleville spring maintains steady pre-load across operating temperature cycles, preventing the gradual loosening or chatter that results from a fatigued or under-spec spring
• OEM Part Number Traceability — ordering by Bomag part number 09290808 gives you a direct cross-reference to BOMAG service documentation, so the correct part reaches the right machine every time

A Belleville spring — also called a conical disc spring or washer spring — is a ring-shaped, slightly domed metal component that stores elastic energy when compressed. In compaction equipment, Belleville springs are commonly used in clutch packs, brake assemblies, bearing pre-load arrangements, and fastener locking systems, where their high load capacity in a very short travel distance makes them well suited to maintaining consistent clamping force within tight axial space. When a Belleville spring fatigues, takes a permanent set, or fractures, the pre-load it was providing is lost, which can lead to clutch slip, brake drag, bearing play, or fastener loosening — all of which degrade machine control and accelerate wear on surrounding components. Replacing a failed spring promptly with the correct OEM specification part restores the intended force profile and protects the integrity of the assembly around it.
