The Bomag 05818025 Sealing Disc is a genuine OEM component designed for Bomag BW 1050 T, BW 850 TR, and BW 85 T trench compactors. Sourced directly from Bomag, this sealing disc matches the exact material grade and dimensional tolerances of the original part. It installs directly into the sealing interface without modification, restoring the integrity of the assembly and protecting internal components from contamination or fluid loss.
Key Features
- OEM-Grade Sealing Material — manufactured to Bomag's original compression and material specifications, ensuring a consistent, leak-free seal across the full operating range of your trench compactor
- Direct-Fit Replacement — dimensionally identical to the original, this sealing disc seats precisely into the existing housing without rework or adjustment
- Confirmed Fitment — compatible with the BW 1050 T, BW 850 TR, and BW 85 T trench compactors, covering the full BW T-series range represented in Bomag's catalog
- Protects Internal Components — a functioning sealing disc prevents fluid ingress and contamination that can accelerate wear on adjacent bearings, shafts, and housings
- Genuine Bomag OEM Part — backed by Bomag's part number 05818025, giving you confidence in authenticity and correct application every time
A sealing disc creates a barrier between mating surfaces or around a rotating or static shaft to prevent the escape of lubricants or the entry of dirt, water, and debris into a critical assembly. In a trench compactor like the BW 1050 T, BW 850 TR, or BW 85 T, maintaining an effective seal is essential to keeping drivetrain and vibration system components properly lubricated and protected under the demanding conditions of trench and backfill work. When a sealing disc wears, cracks, or deforms, it can allow fluid loss or contamination that leads to accelerated component wear and eventual mechanical failure.
