The Bomag 05850265 Seal Kit is a genuine OEM component designed for Bomag BW 100, BW 120, BW 125, BW 135, BW 138, BW 154, and BW 174 series tandem rollers. Sourced directly from Bomag, this seal kit delivers exact material grades, dimensional tolerances, and compression ratings to match the original seals installed at the factory. It is a direct-replacement service kit covering a wide range of tandem roller variants in the BW AD, AC, AP, ACP, and APO families, including BW 100 AD-4, BW 120 AC-4, BW 125 AD-4, BW 154 ACP-4, BW 174 AP-4, and BW 174 AP-4i, among others. Keeping the sealing system in top condition is essential for maintaining hydraulic pressure, preventing fluid loss, and ensuring consistent roller performance across every shift.
Key Features
- OEM Seal Material and Compression Rating — genuine Bomag seals are manufactured to the exact elastomer grade and compression profile specified for these tandem roller hydraulic systems, ensuring a proper seal under operating pressures
- Direct Service Replacement — this kit installs in place of the worn or damaged original seals with no alteration to mating surfaces or hardware, making it the correct choice for scheduled maintenance and emergency repairs alike
- Broad Tandem Roller Coverage — fits a wide range of Bomag tandem rollers including BW 100 AD-4, BW 100 AC-4, BW 120 AD-4, BW 120 AC-4, BW 125 AD-4, BW 125 AC-4, BW 135 AD, BW 138 AD, BW 138 AC, BW 154 AP-4, BW 154 ACP-4, BW 154 AP-4i, BW 174 AP-4, BW 174 AP-4i, BW 174 AP-4f, BW 174 APO-4i, BW 174 APO-4f, and additional BW 154 and PB variants
- Hydraulic Integrity Restored — degraded or leaking seals allow hydraulic fluid to bypass critical circuits, causing erratic drum drive response and loss of compaction force; replacing seals with this kit brings the system back to full operating specification
- Genuine OEM Part Assurance — as an authentic Bomag part under part number 05850265, this kit is verified against Bomag's own parts catalog, so you order with confidence that the kit matches your machine's sealing requirements
A seal kit consolidates all the sealing elements — O-rings, lip seals, and backup rings — required to restore a hydraulic assembly to a leak-free condition. In tandem rollers, hydraulic circuits control drum drive, steering, and vibration systems, so any seal failure can lead to fluid contamination, pressure loss, and unpredictable machine behavior. Replacing worn seals on schedule, using a correctly specified kit like this one, prevents costly secondary damage to pumps, motors, and control valves.
