SMC C85 series ISO 6432 mini air cylinder, double acting, single rod, with built-in magnet (D) for auto switch detection. Basic mounting type (N), 20 mm bore, 250 mm stroke, rubber bumper cushioning and band mounting (B) for auto switches. Piston rod diameter 8 mm with M8 x 1.25 rod thread, G 1\/8 port size. Air operated, 1.0 MPa maximum operating pressure, 1.5 MPa proof pressure, piston speed 50 to 1500 mm\/s, allowable kinetic energy 0.27 J with rubber bumper. Ambient and fluid temperature -10 to 60 C for the built-in magnet type. 250 mm is a standard stroke for the 20 mm bore. Conforms to ISO 6432 and CETOP RP52P.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMPN:\u003c\/strong\u003e CD85N20-250-B · \u003cstrong\u003eSKU:\u003c\/strong\u003e CD85N20250B\u003c\/p\u003e\u003ch2\u003eCD85N20-250-B Applications\u003c\/h2\u003e\u003cp\u003eThe 250 mm stroke makes this C85 suited to long-travel pushing, transfer and lifting duties such as pusher arms, feed slides, diverter gates and stopper mechanisms on conveyors and packaging lines. Rubber bumper cushioning is best for light to moderate loads at controlled speeds; check kinetic energy against the 0.27 J limit and choose the air cushion version for heavier or faster loads. Band-mounted auto switches sense the built-in magnet to give end-position feedback anywhere along the barrel.\u003c\/p\u003e\u003ch2\u003eCD85N20-250-B Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSMC\u003c\/td\u003e\n\u003ctd\u003eManufacturer Part No.\u003c\/td\u003e\n\u003ctd\u003eCD85N20-250-B\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eC85 (ISO 6432)\u003c\/td\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eMini air cylinder, double acting, single rod\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eBore\u003c\/td\u003e\n\u003ctd\u003e20 mm\u003c\/td\u003e\n\u003ctd\u003eStroke\u003c\/td\u003e\n\u003ctd\u003e250 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eCushion\u003c\/td\u003e\n\u003ctd\u003eRubber bumper\u003c\/td\u003e\n\u003ctd\u003eBuilt-in Magnet\u003c\/td\u003e\n\u003ctd\u003eYes (auto switch capable)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eAuto Switch Mounting\u003c\/td\u003e\n\u003ctd\u003eBand mounting (B)\u003c\/td\u003e\n\u003ctd\u003eMounting Style\u003c\/td\u003e\n\u003ctd\u003eBasic (N)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003ePiston Rod Diameter\u003c\/td\u003e\n\u003ctd\u003e8 mm\u003c\/td\u003e\n\u003ctd\u003ePiston Rod Thread\u003c\/td\u003e\n\u003ctd\u003eM8 x 1.25\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003ePort Size\u003c\/td\u003e\n\u003ctd\u003eG 1\/8\u003c\/td\u003e\n\u003ctd\u003eFluid\u003c\/td\u003e\n\u003ctd\u003eAir\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eProof Pressure\u003c\/td\u003e\n\u003ctd\u003e1.5 MPa\u003c\/td\u003e\n\u003ctd\u003eMax.
