The Bomag 05741271 O-Ring is a genuine OEM sealing component designed for Bomag BW-series tandem rollers and single drum rollers, including the BW 100, BW 120, BW 124, BW 125, BW 131, BW 135, BW 138, and BW 115 families. As an authentic Bomag part, this O-Ring is manufactured to the exact material grade and dimensional tolerances required for proper sealing in your machine's hydraulic or fluid circuits. This O-Ring fits a broad range of generation-4, -3, and -5 variants — including AC, AD, SL, SLC, ACW, PDH, and DH configurations — making it a widely applicable service part across multiple Bomag roller platforms. If you're servicing a BW 100 AD-5, BW 120 AD-5, BW 124 DH-5, or any other covered model, part number 05741271 is the correct OEM replacement.
Key Features
- OEM Material Precision — manufactured to Bomag's exact compound and durometer specification, ensuring the correct compression set and sealing performance for hydraulic and fluid applications in these roller platforms
- Direct-Fit Replacement — dimensionally identical to the original, so this O-Ring seats correctly in its groove without adjustment or trimming during reassembly
- Broad Fitment Coverage — fits BW 100, BW 115, BW 120, BW 124, BW 125, BW 131, BW 135, and BW 138 tandem rollers across generation -3, -4, and -5 variants, as well as BW 124 DH-5 and BW 124 PDH-5 single drum rollers
- Leak Prevention — a correctly seated O-Ring maintains circuit integrity, preventing fluid loss that can lead to pressure drop, overheating, or component damage in the roller's hydraulic system
- Genuine Bomag OEM Part — sourced directly from Bomag, carrying the same part number 05741271 referenced in BOMAG service documentation for verified application accuracy
An O-Ring is a molded elastomeric seal used to prevent fluid or air from passing between mating components — typically where a shaft, fitting, or housing comes together in a hydraulic or fluid system. In a tandem roller like the BW 120 or BW 138, O-Rings are found throughout the hydraulic drive system, vibration circuits, and fluid connections, where they maintain pressure and prevent contamination ingress. When an O-Ring degrades, flattens, or takes a permanent set, the resulting leak can cause hydraulic pressure loss, erratic drum behavior, or fluid contamination — making timely replacement essential to keeping the roller operating correctly.
