CDU20-90D Applications
The CDU20-90D is the long stroke version of the CU free mount cylinder, giving 90 mm of travel from a 20 mm bore while retaining the compact square mounting body. It fits transfer, lifting, pushing and guarding applications where a longer reach is needed but bracket space is limited, such as conveyor diverters, product pushers, magazine feeders and access doors. The built-in magnet accepts auto switches for end-of-stroke confirmation.
