Key Features

• Genuine OEM Construction — manufactured to Bomag's original specifications, matching the precise extension force, stroke length, and end-fitting geometry of the part it replaces
• Direct Drop-In Fitment — mounts to the original brackets and pivot points without modification, using the same hardware configuration as the factory-installed unit
• Broad Tandem Roller Coverage — fits the BW 161 AC-2, BW 161 AD-2, BW 164 AC-2, BW 164 AD, BW 164 AD-2, BW 202 AD-2, and BW 202 AHD-2 tandem rollers
• Consistent Damping and Support — maintains calibrated gas pressure to hold panels, hoods, or access covers securely in the open position, protecting operators during inspections and service
• Safe Access Every Time — a correctly functioning gas spring prevents uncontrolled hood or cover drop, reducing the risk of injury during routine maintenance on your tandem roller

A gas spring is a sealed, pressurized cylinder that uses compressed gas — typically nitrogen — to generate a controlled, consistent extension force across its full stroke. On Bomag tandem rollers, gas springs are commonly used to support engine hoods, access panels, and service covers, holding them open hands-free during maintenance. When a gas spring loses pressure or develops a leak, the supported panel can drop unexpectedly, creating a safety hazard and making routine service more difficult. Replacing a worn gas spring with a genuine Bomag part restores the original holding force and ensures the cover stays where it should throughout the service interval.
