The Bomag 05546828 O-Ring is a genuine OEM sealing component designed for a wide range of Bomag single drum rollers, tandem rollers, and cold milling machines, including the BW 213, BW 226, BW 100, BW 120, and BM 500/15 series. As a factory-sourced part, this O-Ring meets the original material and dimensional specifications Bomag engineered into these machines. It delivers a drop-in fit across all compatible models listed, covering multiple generations of single drum rollers such as the BW 213 DH-3, BW 213 DH-4, BW 213 DH-5, BW 226 DH-4, and BW 332, as well as tandem rollers including the BW 100 AD-5, BW 100 AC-5, BW 115 AC-5, BW 120 AD-5, BW 120 AC-5, BW 131 AD-5, and cold milling machines such as the BM 500/15 and BM 600/15. When a worn or damaged O-Ring is left in service, it allows fluid to bypass the seal, leading to leaks and loss of hydraulic or cooling system integrity — replacing it with the correct OEM part restores the seal immediately.
Key Features
- OEM Material Specification — manufactured to Bomag's original compound and durometer rating, ensuring the sealing lip compresses and seats correctly under operating pressures
- Exact Dimensional Fit — matches the original groove diameter and cross-section precisely, allowing this O-Ring to seat without modification across all compatible applications
- Broad Multi-Machine Coverage — fits BW 213 and BW 226 single drum rollers, BW 100, BW 115, BW 120, and BW 131 tandem rollers, and BM 500/15 and BM 600/15 cold milling machines across multiple production generations
- Leak Prevention at the Source — a correctly installed O-Ring maintains a consistent fluid boundary, preventing hydraulic or coolant loss that can lead to system pressure drop or overheating
- Fluid System Integrity — using the correct OEM-spec seal in fuel, hydraulic, or cooling circuits is essential; an incorrect compound can swell, shrink, or degrade prematurely under operating temperatures and fluid chemistry
An O-Ring is a circular elastomeric seal fitted into a machined groove to prevent fluid or gas from passing between mating surfaces or through a port. In heavy compaction and milling equipment, O-Rings appear throughout hydraulic circuits, cooling systems, and fuel delivery components, where they must maintain a reliable seal under sustained pressure and temperature cycling. When an O-Ring hardens, cracks, or is compressed beyond its service limit, it loses its ability to seal, allowing fluid to escape — which can quickly escalate from a minor weep to a system-compromising leak if the seal is not replaced promptly.
