The Bomag 05546146 Pressure Spring is a genuine OEM component designed for a wide range of Bomag tandem rollers, single drum rollers, cold milling machines, and recycler/stabilizers. As an authentic Bomag part, this pressure spring is manufactured to the same specifications as the original, ensuring correct operation across compatible machines including BW 100, BW 120, BW 174, BW 202, BW 203, and BW 179 series tandem and single drum rollers, BM 1200/30 and BM 1300/30 cold milling machines, and MPH 121 and MPH 122 recycler/stabilizers. With broad fitment coverage across multiple generations and configurations, this pressure spring is the correct choice for operators maintaining their Bomag equipment to OEM standards.
Key Features
- Genuine OEM Spring Rate and Tension — manufactured to Bomag's original specification, delivering the correct compression force and return characteristics this part demands in service
- Direct-Fit Replacement — dimensioned to match the original mounting points and seat geometry, so this spring installs into the existing assembly without rework or modification
- Broad Bomag Fleet Coverage — fits Bomag BW-series tandem rollers, BW-series single drum rollers, BM 1200/30 and BM 1300/30 cold milling machines, and MPH 121 and MPH 122 recycler/stabilizers across multiple machine generations
- Consistent Mechanical Response — a correctly tensioned pressure spring maintains proper clamping, actuation, or return force in the assembly it serves, preventing erratic operation caused by a fatigued or broken spring
- Genuine Bomag Part Number Assurance — sourced and sold under part number 05546146, confirming you are receiving the correct spring for your machine and not a mismatched substitute
A pressure spring stores and releases mechanical energy to maintain consistent force on a mating component — whether that is holding a valve seated, returning a lever to its neutral position, or maintaining clamping pressure within an assembly. When a pressure spring weakens or breaks, the component it acts on loses consistent force, leading to poor response, incorrect engagement, or accelerated wear on surrounding parts. Replacing a worn pressure spring with a genuine Bomag 05546146 restores the correct mechanical behavior the system was designed around, keeping the machine operating as intended across demanding compaction and milling applications.
