Festo
552789
ISO cylinder CRDSNU-20-
The Festo part number 552789 is a double-acting industrial component featuring a 20 mm piston diameter with a stroke range of 1 mm to 320 mm, built on the ISO 6432 norm with structural design comprising a piston, piston rod, and cylinder barrel. It operates at a pressure range of 0.1 MPa to 1 MPa (1 bar to 10 bar) in any mounting position, offering position sensing via proximity switch and multiple cushioning configurations including elastic cushioning rings, self-adjusting pneumatic end-position cushioning, and adjustable pneumatic cushioning at both ends. Certified for explosion protection in ATEX and UKEX zones 1, 2, and 21 with EPL Gb and EPL Db ratings, this component supports numerous variants such as heat-resistant seals, unlubricated operation, and increased chemical resistance.
