Bomag 05546155 Pressure Spring

The Bomag 05546155 Pressure Spring is a genuine OEM component designed for a broad range of Bomag tandem rollers, single drum rollers, cold milling machines, and recyclers/stabilizers — including BW-series tandem and single drum rollers, BM 1200/30 and BM 1300/30 cold milling machines, and MPH 121 and MPH 122 recyclers/stabilizers. As a factory-sourced part, this pressure spring is manufactured to the same specifications as the original, ensuring a correct, trouble-free installation with no guesswork on fit. Sourced directly from Bomag, part number 05546155 is the right choice when precision and confidence matter on your equipment.

Key Features

• Genuine OEM Spring Specification — manufactured to Bomag's original load and deflection tolerances, so compression force and return behavior match what the machine was engineered around
• Direct-Fit Replacement — this pressure spring seats and retains exactly as the original, requiring no adjustment to surrounding hardware or spring seats
• Broad Cross-Machine Coverage — fits a wide range of Bomag equipment including BW-series tandem rollers (BW 100 through BW 205 families), BW-series single drum rollers, BM 1200/30 and BM 1300/30 cold milling machines, MPH 121 and MPH 122 recyclers/stabilizers, and C-series single drum rollers
• Consistent Clamping and Return Force — a correctly rated pressure spring maintains the designed actuation force in the system it serves, preventing sluggish engagement, premature wear on mating components, or loss of system responsiveness
• Corrosion-Resistant Construction — OEM spring material and surface treatment resist the moisture, debris, and compaction-related stress cycles common in roller and milling-machine service environments

A pressure spring is a coiled or formed spring that applies a controlled, consistent force against a mating component — holding a valve, lever, piston, or mechanism in its correct operating position and returning it after actuation. In compaction and milling equipment, pressure springs appear throughout hydraulic control circuits, fuel system components, and mechanical linkages, where maintaining the right spring load is critical to consistent machine response. When a pressure spring weakens, takes a set, or breaks, the affected system may respond erratically, fail to return to neutral, or cause accelerated wear on the parts it bears against — making timely replacement with a correctly rated OEM spring essential to keeping the machine operating as intended.
