The Bomag 09290011 Belleville Spring is a genuine OEM component designed for Bomag BW 213 D, BW 177 DH-4, BW 179 DH-4, BW 211 D-4, BW 213 D-4, BW 213 DH-4, and BW 226 DH-4 single drum rollers. Sourced directly from Bomag, this Belleville Spring meets the same specifications as the original part installed at the factory, ensuring a direct, trouble-free fit. If your roller is showing signs of spring fatigue, loss of clamping force, or inconsistent tension, replacing this component with part number 09290011 restores correct mechanical function across the full range of compatible machines.
Key Features
- Genuine OEM Clamping Integrity — manufactured to Bomag's original spring-load and deflection specifications, ensuring consistent clamping force without risk of stress failure from undersized or incorrect-rate substitutes
- Direct-Fit Replacement — matches the original disc geometry and bore dimensions, dropping straight into position without rework or shimming
- Broad Single Drum Roller Coverage — fits the BW 213 D, BW 177 DH-4, BW 179 DH-4, BW 211 D-4, BW 213 D-4, BW 213 DH-4, and BW 226 DH-4 single drum rollers, making it a versatile stock item for fleets running multiple Bomag models
- Sustained Tension Under Load — Belleville springs operate under high cyclic compression; a correctly rated OEM spring maintains its load curve over time, preventing the slack and vibration that a fatigued spring allows
- Verified Part Number Traceability — ordering by Bomag part number 09290011 confirms you are receiving the correct spring profile for these machines, eliminating the fitment risk of sourcing by dimension alone
A Belleville spring — also called a conical disc spring — is a washer-shaped component engineered to exert a precise, controlled axial clamping force within a mechanical assembly. On Bomag single drum rollers, these springs are used in critical clamping and tensioning applications where a consistent, high load must be maintained in a compact axial space. When a Belleville spring fatigues or fractures, the assembly it supports loses its designed preload, which can lead to loosening, vibration, premature wear of surrounding components, and ultimately mechanical failure. Replacing a worn spring promptly with the correct OEM part restores the engineered load profile and protects the integrity of the surrounding assembly.
