The Bomag 05586176 O-Ring is a genuine OEM sealing component designed for Bomag BW 145, BW 177, and BW 179 series single drum rollers. As an authentic Bomag part, this O-Ring is manufactured to the same specifications as the original, ensuring a proper seal and dependable service life. This O-Ring covers an extensive range of generation-3, generation-4, and generation-5 variants across the BW 145 and BW 177 families, as well as BW 179 models, including DH, PDH, DHC, PDHC, and D configurations. When you need a confirmed-fit seal replacement sourced directly from the OEM, part number 05586176 is the correct choice for your machine.
Key Features
- Genuine OEM Sealing Material — manufactured by Bomag to the same compound and durometer specification as the original, delivering consistent compression and chemical resistance in hydraulic or fluid-circuit applications
- Direct-Fit Replacement — dimensionally identical to the factory O-Ring, seating into the original groove without rework or adaptation
- Broad Single Drum Roller Coverage — fits BW 145, BW 177, and BW 179 single drum rollers across multiple generation variants, including D, DH, PDH, DHC, and PDHC configurations from the -3 through -50 series
- Leak Prevention — a correctly seated O-Ring maintains fluid containment in the circuit it seals; a worn or damaged O-Ring allows fluid to bypass the seal, leading to pressure loss, contamination, and potential component damage
- Verified Part Number Fitment — ordering by Bomag part number 05586176 confirms you are receiving the correct seal geometry for your specific roller variant, eliminating guesswork on sizing
An O-Ring is a circular elastomeric seal that sits in a machined groove between two mating surfaces or within a port, creating a pressure-tight barrier that prevents fluid or air from escaping the circuit. On single drum rollers like the BW 145, BW 177, and BW 179, O-Rings appear throughout the hydraulic drive system, drum vibration circuit, and ancillary fluid connections, where they must withstand pressure cycling and exposure to hydraulic fluid over long service intervals. When an O-Ring degrades, flattens, or takes a set, the resulting leak can cause hydraulic pressure drop, erratic drum vibration output, or fluid contamination — making timely replacement essential to keeping the roller performing at specification.
