Series MY1B Cushion Capacity Cushion Selection Absorption Capacity of Air Cushion and Stroke Adjustment Units Air Cushion Stroke Bore size [mm] Air cushions are a standard feature on mechanically jointed rodless cylinders. The air cushion mechanism is incorporated to prevent excessive impact of the piston with high kinetic energy at the stroke end. The purpose of air cushion, thus, is not to decelerate the piston near the stroke end.
