A rack and pinion system uses two simple components to move a slide gate: a flat, toothed bar (the rack) that runs along the bottom of the gate, and a round gear (the pinion) mounted to the opener's motor. As the motor turns the pinion, its teeth engage the rack and push or pull the gate along its track. The result is a direct, mechanical drive with no slipping, no stretching, and consistent force across the full travel of the gate.
How It Compares to Chain Drive
Chain drive openers use a loop of chain to transfer power from the motor to the gate, similar to a bicycle drivetrain. They get the job done, but the chain introduces slack over time, requires periodic tensioning, and can wear unevenly under heavy or frequent use. Rack and pinion eliminates those variables. The gear-to-rack engagement is rigid and consistent, which means less maintenance, smoother operation, and better long-term reliability, especially in commercial or high-cycle applications.
Choosing the Right Model
FAAC's rack and pinion lineup covers a wide range of applications, from standard residential driveways to heavy-duty industrial entrances. Models are rated by gate weight and track length, so it's easy to match the opener to the job. Whether you're running a single-family driveway or a high-cycle commercial entrance, there's a model built for it.
