The Bomag 58040185 Sealing Ring is a genuine OEM component designed for Bomag BW 124, BW 145, and BW 120 series single drum and tandem rollers, as well as C 815 C and C 825 C single drum rollers. Sourced directly from Bomag, this sealing ring matches the original specification to deliver a proper, leak-free installation without modification. It is confirmed compatible across a broad range of BW-series single drum and tandem roller variants, including BW 124 DH-3, BW 124 PDH-3, BW 145 D-3, BW 145 DH-3, BW 145 PDH-3, BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 125 AD-4, BW 125 AC-4, BW 124 DH-4, BW 124 DH-5, BW 124 PDH-5, and additional generation variants. Using an authentic Bomag replacement ensures the seal performs exactly as engineered, protecting internal components from contamination and fluid loss throughout the service life of your machine.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Bomag's original material and dimensional specification, delivering the compression characteristics needed for a consistent, leak-free seal in demanding roller applications
- Direct Drop-In Replacement — engineered to the same profile and tolerances as the original, allowing this sealing ring to seat correctly in its housing without reworking or shimming
- Broad BW and C-Series Coverage — fits BW 124, BW 145, and BW 120 series single drum rollers, BW 100, BW 120, and BW 125 series tandem rollers, and C 815 C and C 825 C single drum rollers, spanning multiple generation variants
- Protects Critical Internal Components — a properly functioning sealing ring prevents hydraulic fluid or lubricant from escaping the assembly; a failed seal leads to fluid loss, accelerated wear, and potential component damage
- Correct Part Number Confidence — ordering by Bomag part number 58040185 ensures you receive the exact ring dimensioned for your machine's assembly, eliminating the risk of fitment errors common with generic alternatives
A sealing ring creates a pressure-tight barrier between mating surfaces or around rotating and reciprocating components, preventing fluid or lubricant from leaking out and contaminants from entering the assembly. On heavy compaction equipment like Bomag single drum and tandem rollers, these seals are critical to maintaining hydraulic system pressure and protecting bearings, shafts, and other internal parts from premature wear. When a sealing ring deteriorates — through heat cycling, compression set, or mechanical damage — the resulting leak can cause fluid loss, loss of drive or vibration performance, and accelerated wear across connected components if left unaddressed.
