The Bomag 05585055 Sealing Ring is a genuine OEM component designed for BW 124 and C 815 series single drum rollers. As a direct-from-BOMAG replacement, this sealing ring matches the original specification and installs without modification across the full range of compatible machines. This part is confirmed to fit BW 124 DH-3, BW 124 PDH-3, BW 124 DH-4, BW 124 PDH, BW 124 DH-5, BW 124 PDH-5, BW 124 DH-40, BW 124 PDH-40, C 815 C, and C815D single drum rollers, covering multiple generations of the lineup. When a sealing ring wears or fails, fluid loss and contamination risk follow quickly — sourcing an OEM replacement like this one keeps your machine running to specification.
Key Features
- Genuine OEM Sealing Integrity — manufactured to BOMAG's original material and dimensional specification, ensuring consistent compression and fluid containment specific to this roller's sealing application
- Drop-In Replacement — engineered to match the original sealing ring geometry exactly, allowing straightforward installation without reworking seal grooves or mating surfaces
- Broad Generation Coverage — fits BW 124 DH-3 through BW 124 DH-5, BW 124 PDH-3 through BW 124 PDH-5, BW 124 DH-40, BW 124 PDH-40, C 815 C, and C815D single drum rollers
- Prevents Fluid Loss and Contamination — a correctly seated sealing ring keeps hydraulic or lubricating fluid where it belongs, protecting surrounding components from accelerated wear
- Leak Prevention Supports Safe Operation — fluid leaks from a failed seal can create slippery surfaces and mask other developing faults; replacing the sealing ring promptly maintains safe, compliant machine operation
A sealing ring creates a pressure- and fluid-tight barrier between mating components, preventing the escape of hydraulic fluid, gear oil, or coolant and blocking the ingress of dirt and moisture. On single drum rollers like the BW 124 and C 815 series, these rings are found throughout the drivetrain, hydraulic circuit, and drum assembly, where maintaining a clean and contained fluid environment is critical to consistent compaction performance. When a sealing ring degrades — through heat cycling, compression set, or simple age — leaks develop that can lead to component overheating, loss of hydraulic pressure, and accelerated wear across the system.
