The Bomag 05728740 Piston Seal is a genuine OEM component designed for Bomag BW-series tandem rollers and single drum rollers. Sourced directly from Bomag, this piston seal delivers the exacting dimensional tolerances and material grade required to maintain hydraulic integrity across a wide range of BW-series machines, including the BW 184 AD, BW 174 AD AM, BW 177 DH-4, BW 206 AD-5 AM, and BW 191 AD-5 AM. As a genuine OEM part, it matches the original specification precisely, ensuring correct sealing compression and long service life in demanding compaction applications. Confirmed fitment spans tandem rollers and single drum rollers across multiple BW generations, from the BW 141 AD-4 AM through the BW 174 ACP-5 AM and beyond.
Key Features
- OEM-Grade Sealing Material — manufactured to Bomag's original compound and durometer specification, delivering the compression and resilience a hydraulic piston seal demands under continuous pressure cycling
- Drop-In Hydraulic Replacement — dimensionally identical to the original, this seal seats correctly in the piston groove without modification, restoring a leak-free hydraulic circuit
- Broad BW-Series Coverage — fits a wide range of Bomag tandem rollers and single drum rollers, including the BW 154 AD-2, BW 170 AD-2 AM, BW 177 DH 3, BW 177-5, BW 203 AD-4 AM, and BW 174 ACP-5 AM, among others
- Hydraulic Circuit Performance — a correctly functioning piston seal maintains drum drive and vibration system pressure; a worn or failed seal causes pressure loss, sluggish drum response, and uneven compaction output
- Verified Genuine OEM Part — supplied under Bomag part number 05728740, confirming authenticity and traceability for fleet maintenance records
A piston seal sits inside a hydraulic cylinder and creates a pressure-tight barrier between the two sides of the piston, allowing hydraulic fluid to drive controlled, forceful movement. In Bomag rollers, hydraulic cylinders govern functions such as drum drive, steering, and vibration amplitude adjustment — all of which depend on the seal holding pressure without bypass. When a piston seal degrades, internal fluid bypasses the piston, pressure drops, and the affected system loses force and responsiveness. Replacing a worn seal promptly with a correctly specified part, such as this genuine Bomag component, restores full hydraulic efficiency and prevents accelerated wear on cylinder walls and other hydraulic components.
