Bomag 05729490 Pressure Spring

The Bomag 05729490 Pressure Spring is a genuine OEM component designed for a wide range of Bomag single drum rollers, pavers, refuse/landfill compactors, and soil compactors — including BW 219 and BW 226 series single drum rollers, BF 800 and BF 900 series pavers, and BC-series compactors. Sourced directly from Bomag, this pressure spring delivers an exact match to the original specification, ensuring proper tension and mechanical function without modification. Confirmed fitment spans models including the BW 219 D-5, BW 219 DH-5, BW 219 PD-5, BW 219 PDH-5, BW 226-5, BW 226 DH-5, BW 226 PDH-5, BW 226 DI-5, BF 800 C S600-4i, BF 800 P S600-4i, BF 900 C S500, BF 900 C S600, BF 900 C S600-4i, BC 572 RB-2, BC 473 RB-3, and BC 473 EB-3, among others. When you need the correct spring the first time, part number 05729490 is the verified OEM choice.

Key Features

• Genuine OEM Spring Rate — manufactured to the exact tension and compression specification Bomag engineers set for this application, ensuring the spring performs as intended within the assembly
• Direct-Fit Replacement — dimensionally identical to the original, this pressure spring seats and loads correctly in the factory mounting position with no rework required
• Broad Verified Fitment — fits BW 219 and BW 226 single drum rollers (including -4i and -5 generation variants), BF 800 and BF 900 pavers, BC 572 RB-2 and BC 473 RB-3 refuse/landfill compactors, and the BC 473 EB-3 soil compactor
• Consistent Mechanical Force — a properly functioning pressure spring maintains the correct clamping or return force in its assembly; a fatigued or broken spring causes erratic operation, component wear, and potential system failure
• Long-Term Spring Integrity — OEM material and heat-treatment standards resist fatigue and set over time, keeping spring rate stable across demanding compaction and paving cycles

A pressure spring stores and releases mechanical energy to maintain consistent force or return motion between two components in an assembly. In heavy compaction and paving equipment, these springs are commonly used to hold valves, linkages, or mechanical elements under controlled tension so they respond predictably during operation. When a pressure spring fatigues, loses its rate, or breaks, the assembly it supports loses the force balance it depends on — leading to inconsistent performance, accelerated wear on adjacent components, or outright mechanical failure. Replacing a worn spring with the correct OEM part restores the designed force characteristic and protects the surrounding system.
