DSI
Dust Seal
Advantages and Characteristics
DSI is a single-acting dust seal, with an outer diameter design with interference to ensure that the periphery of the dust ring is tightly against the groove bottom, preventing external pollutants from entering the interior of the cylinder.
DSI is suitable for medium to low pollution environments, such as indoor hydraulic presses and injection molding machines.
