The Bomag 05729228 O-Ring is a genuine OEM sealing component designed for Bomag BW-series tandem rollers and single drum rollers. As a direct OEM replacement, this O-Ring is manufactured to the same material and dimensional specifications as the original, ensuring a consistent seal in the hydraulic or fluid system where it is installed. This part fits a broad range of BW-series machines, including BW 100 AD-5, BW 120 AD-5, BW 120 SL-5, BW 141 AD-4, BW 145 D-5, BW 151 AD-4, BW 154 AD-4, BW 161 AD-4, BW 177 D-5, BW 177 DH-4, BW 177 DHC-4, BW 177 PDHC-4, BW 177 PDH-4, BW 177 D-5 PL, BW 179 DH-4, BW 179 DHC-4, and BW 179 PDH-4 single drum rollers, as well as BW 141 AD-4 AM, BW 151 AC-4, BW 151 AC-4 AM, BW 151 AD-4 AM, BW 154 AD-4 AM, BW 161 AC-4, BW 161 ADO-4, BW 161 AD-4 EU-Flex, and BW 145 D-5 PL variants. Verify part number 05729228 against your machine's service documentation before ordering to confirm the correct application.
Key Features
- OEM Sealing Material — manufactured to Bomag's original compound and durometer specification, delivering the same compression and chemical resistance as the factory-installed seal
- Exact-Dimension Replacement — matches the original cross-section and inner diameter so this O-Ring seats correctly in its groove without shimming or modification
- Broad BW-Series Coverage — fits BW 100 AD-5, BW 120 AD-5, BW 145 D-5, BW 177 D-5, BW 179 DH-4, and many additional BW tandem and single drum roller variants listed above
- Leak Prevention — a properly seated O-Ring maintains system pressure and prevents fluid loss; a worn or damaged seal leads to leaks that compromise hydraulic performance and can cause component damage
- Genuine Bomag Part — sourced directly from Bomag as an OEM component, with part number 05729228 traceable to the original equipment catalog
An O-Ring is a circular elastomeric seal designed to sit in a machined groove and compress between two mating surfaces, preventing fluid or air from passing through the joint. In Bomag rollers, O-Rings are used throughout hydraulic circuits, pump housings, valve blocks, and other sealed assemblies to maintain pressure integrity and keep contaminants out. When an O-Ring degrades — through heat cycling, compression set, or chemical exposure — it loses its ability to seal, leading to fluid leaks, pressure loss, and potential damage to surrounding components.
