Key Features
- Genuine OEM Cartridge Construction — Manufactured to Bomag's exact pressure and flow tolerances, ensuring the safety cartridge performs its protective function precisely as the hydraulic system demands.
- Direct-Fit Replacement — Engineered to seat and seal correctly in the original cartridge bore, with matching thread form and body dimensions for a straightforward swap.
- Broad Tandem Roller Coverage — Compatible with a wide range of Bomag tandem rollers including the BW 100 AC-3, BW 120 AD-3, BW 125 ADH, BW 135 AD, BW 138 AD, and related variants across the AC and AD series.
- Hydraulic System Protection — A correctly functioning safety cartridge limits pressure spikes that can damage pumps, motors, and valves; a worn or failed cartridge puts the entire hydraulic circuit at risk.
- Pressure Relief Integrity — As a safety-critical hydraulic component, using the correct OEM cartridge maintains the intended relief setting, protecting both the machine and the operator from uncontrolled pressure events.
A safety cartridge is a pressure-relief or safety-valve element within the hydraulic circuit of a tandem roller. Its primary role is to open at a precisely calibrated pressure threshold, diverting flow and preventing dangerous over-pressurization that could rupture hoses, damage hydraulic components, or cause loss of machine control. When this cartridge wears, sticks, or fails to seal correctly, the hydraulic system loses its pressure protection, leading to erratic performance, component damage, or unsafe operating conditions. Replacing it with the correct OEM part ensures the relief setting is restored to the roller's design specification.
