The Bomag 09312990 Radial Seal is a genuine OEM sealing component designed for a wide range of Bomag tandem rollers, walk-behind rollers, and reversible vibratory plates, including the BW 90 AD, BW 65, BW 75 AD-2, BPR 75/60 D, and BPR 100/80 D. Sourced directly from Bomag, this radial seal delivers the exact material grade, dimensional tolerancing, and compression characteristics required to maintain proper sealing in demanding compaction environments. This genuine OEM part carries part number 09312990 and matches the original specification for every compatible machine in the fitment list. When seal integrity matters, choosing the correct OEM component is the most reliable path to maintaining machine performance and protecting critical internal assemblies.
Key Features
- Genuine OEM Sealing Integrity — manufactured to Bomag's exact material and compression specifications, ensuring the lip geometry and elastomer grade match what the original design requires for effective sealing under vibration and load.
- Drop-In Replacement — engineered to the original dimensions so this radial seal seats correctly without modification, maintaining the proper housing fit and shaft contact needed for a leak-free installation.
- Broad Fitment Coverage — fits Bomag tandem rollers including the BW 90 AD, walk-behind rollers including the BW 62 H, BW 65, BW 65 H, BW 65-H, BW 65 S-2, BW 75 AD-2, and BW 75 S-2, and reversible vibratory plates including the BPR 50/52 D, BPR 50/52 D-2, BPR 50/52 D-3, BPR55, BPR 65/52 D-3, BPR 65/70 D, BPR 70/70 D, BPR 75/60 D, BPR 75/60 D-2, BPR 75/60 D-3, BPR 75/60 HD-3, and BPR 100/80 D.
- Protects Critical Internal Components — a correctly functioning radial seal keeps lubricants in and contaminants out of rotating assemblies; a worn or failed seal allows oil loss and ingress of dirt, accelerating wear on bearings and drive components.
- Fluid and Contamination Control — the elastomer construction resists breakdown from exposure to hydraulic fluid, gear oil, and the continuous vibration loads typical of vibratory compaction equipment, maintaining a reliable dynamic seal over the service life of the component.
A radial seal — also called a shaft seal or lip seal — sits around a rotating shaft and forms a dynamic barrier between the inside of a housing and the external environment. Its primary job is to retain lubricating oil or grease within the assembly while preventing dirt, water, and debris from entering. In compaction equipment like rollers and vibratory plates, these seals operate under constant vibration and variable loads, making the correct material grade and dimensional fit essential. When a radial seal wears out or is incorrectly sized, oil leaks develop, lubrication is lost, and internal components such as bearings and gears can suffer rapid wear or failure.
