TheBendix rotochamberis designed to convert air pressure into mechanical force on heavy-duty commercial vehicles. Unlike standard chambers, therolling-style diaphragmensures a constant output and uniform performance throughout the entire stroke. Each model is sized by its effective diaphragm area (e.g.,Type 30provides 30 sq. in. of pressure surface), allowing for a wide range of output forces and stroke lengths. Built for durability, the unit features a moisture-sealing boot and a rugged clamped design.
