The Bomag 320010579 Sealing Ring is a genuine OEM component designed for Bomag BM-series cold milling machines, including the BM 1200/30 and BM 1300/30. Sourced directly from Bomag, this sealing ring matches the original equipment specification for a drop-in replacement with no guesswork. It is compatible across multiple variants of the BM 1000/30, BM 1200/30, and BM 1300/30 cold milling machine family, covering standard, dash-2, and T3 engine-tier configurations. When a sealing ring wears or fails, fluid leaks and contamination can follow — replacing it promptly with part number 320010579 keeps your milling machine operating cleanly and efficiently.
Key Features
- Genuine OEM Sealing Material — manufactured to Bomag's original compound and dimensional tolerances, ensuring the correct compression set and leak-free seal under milling machine operating pressures and temperatures.
- Direct Drop-In Replacement — profiles and dimensions match the original installation point exactly, so this sealing ring seats correctly without trimming, shimming, or additional hardware.
- Broad BM-Series Coverage — fits BM 1000/30-2, BM 1200/30, BM 1200/30-T3, BM 1300/30, BM 1300/30-2, and BM 1300/30-T3 cold milling machines, spanning standard and Tier 3 variants.
- Leak and Contamination Prevention — a correctly seated sealing ring keeps hydraulic or lubricating fluid contained, protecting internal milling machine components from contamination-related wear.
- Fluid System Integrity — on cold milling equipment, a compromised seal can allow abrasive debris or water ingress into fluid circuits, accelerating component damage; replacing this ring at the first sign of seepage is critical to protecting those circuits.
A sealing ring creates a pressure-tight barrier between mating surfaces or around a shaft, preventing fluid from escaping the system and keeping external contaminants out. In a cold milling machine like the BM 1200/30 or BM 1300/30, sealing rings appear throughout hydraulic, lubrication, and cooling circuits where reliability under continuous vibration and load is essential. When a sealing ring degrades — cracking, hardening, or losing its compression — the resulting leak can starve downstream components of lubrication or hydraulic pressure, leading to accelerated wear or unplanned stops on the job.
