- Leak Prevention — a correctly seated radial seal keeps lubricants in and contaminants out, protecting bearings and rotating components from premature wear and fluid loss
- Genuine Bomag Part — part number 09311911 is an authentic OEM component, giving you full confidence in fit and long-term sealing performance across service intervals
A radial seal — sometimes called a shaft seal or lip seal — wraps around a rotating shaft to contain lubricating oil or grease within a housing while blocking dirt, water, and debris from entering. In walk-behind rollers and trench compactors, these seals are typically found at drum drive shafts, gearbox outputs, and bearing carriers, where rotational movement would otherwise work grease or oil out of the assembly. When a radial seal hardens, cracks, or wears, lubricant escapes and abrasive contaminants reach the bearing surfaces, accelerating wear and ultimately leading to component failure — making timely seal replacement a straightforward way to protect the drivetrain and extend the service life of the machine.
