Bomag 05556039 Sealing Ring

The Bomag 05556039 Sealing Ring is a genuine OEM component designed for Bomag BW-series tandem rollers. Sourced directly from Bomag, this sealing ring delivers an exact match to the original specification, ensuring a proper seal without modification or guesswork. This part fits an extensive range of BW tandem roller models, including the BW 80 AD-2, BW 120 AD-5, BW 161 AD-5, BW 174 AP-4, BW 202 AD-5, and many others across multiple generations of the BW tandem roller lineup. Choosing a genuine OEM replacement means the sealing ring integrates seamlessly with existing hardware, maintaining the system integrity your machine depends on.

Key Features

• Genuine OEM Sealing Integrity — manufactured to Bomag's original material and dimensional standards, ensuring the compression and sealing performance expected of this ring in hydraulic or fluid-carrying circuits
• Direct-Fit Replacement — matches the original sealing ring profile exactly, dropping into place without reworking ports, housings, or mating surfaces
• Broad BW Tandem Roller Coverage — fits a wide range of BW-series tandem rollers spanning compact models such as the BW 80 AD-2 through mid-size units including the BW 151 AD-5 and BW 174 AP-4, and larger machines such as the BW 202 AD-5 and BW 206 AD-5
• Leak Prevention — a correctly seated sealing ring prevents fluid loss that would otherwise lead to pressure drop, contamination, or damage to surrounding components
• Fluid System Safety — maintaining a sound seal in hydraulic or fuel circuits is critical to safe roller operation; a worn or extruded ring can cause uncontrolled fluid loss, making timely replacement essential

A sealing ring creates a pressure-tight barrier between mating components in a fluid circuit — whether hydraulic, fuel, or cooling — preventing leaks at joints, ports, and housings. When the ring is in good condition, fluid stays contained and system pressure remains stable, allowing the roller's hydraulic drive, vibration, and steering systems to operate as intended. As a sealing ring wears, hardens, or takes a set, it loses its ability to conform to the mating surfaces, resulting in seepage or outright leaks that can cause pressure loss, contamination of surrounding components, and accelerated wear throughout the system.
