{"product_id":"cd85n2540cb","title":"SMC CD85N2540CB (CD85N25-40C-B) - Mini Air Cylinder, 25mm Bore, 40mm Stroke","description":"\u003cp\u003eSMC CD85N2540CB Mini Air Cylinder — 25 mm bore, 40 mm stroke, air cushion, band-mount auto switch type. SMC CD85N25-40C-B is a C85 series ISO 6432 mini air cylinder, double acting, single rod, with a 25 mm bore and 40 mm stroke. The CD85N prefix denotes a built-in magnet (D) for auto switch mounting and an N head cover, the basic type with integrated clevis. The C suffix specifies air cushion in place of the standard rubber bumper, and the B suffix specifies band-type auto switch mounting. 40 mm is a listed standard stroke for the 25 mm bore and exceeds the 25 mm minimum stroke required for the air-cushion option, so the configuration is valid per the official SMC C85\/C75 catalog. Official specifications for the 25 mm bore: fluid air, proof pressure 1.5 MPa, maximum operating pressure 1.0 MPa, minimum operating pressure 0.05 MPa, piston speed 50 to 1500 mm\/s, allowable kinetic energy 0.97 J with air cushion, port size G1\/8, piston rod diameter 10 mm, rod end thread M10 x 1.25. Non-lube operation. Ambient and fluid temperature -20 to 80 degrees C without auto switch, -10 to 60 degrees C with auto switch. Conforms to ISO 6432 and CETOP RP52P.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMPN:\u003c\/strong\u003e CD85N25-40C-B · \u003cstrong\u003eSKU:\u003c\/strong\u003e CD85N2540CB\u003c\/p\u003e\u003ch2\u003eCD85N25-40C-B Applications\u003c\/h2\u003e\u003cp\u003eA short 40 mm cushioned stroke suits high-cycle clamping, stopping, ejecting and indexing on assembly jigs, packaging machines and small conveyors. The air cushion decelerates the piston before it reaches the end cover, cutting impact noise and mechanical shock where the cylinder runs fast and often, which extends seal and bearing life over a rubber-bumper equivalent. The slim ISO 6432 round body fits tight frames, and the built-in magnet supports band-mounted auto switches for end-of-stroke PLC feedback.\u003c\/p\u003e\u003ch2\u003eCD85N25-40C-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\u003eCD85N25-40C-B\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eC85\u003c\/td\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eMini Air Cylinder, ISO 6432 Standard\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eAction\u003c\/td\u003e\n\u003ctd\u003eDouble acting, single rod\u003c\/td\u003e\n\u003ctd\u003eBore\u003c\/td\u003e\n\u003ctd\u003e25 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eStroke\u003c\/td\u003e\n\u003ctd\u003e40 mm\u003c\/td\u003e\n\u003ctd\u003eCushion\u003c\/td\u003e\n\u003ctd\u003eAir cushion (C)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eBuilt-in Magnet\u003c\/td\u003e\n\u003ctd\u003eYes (D)\u003c\/td\u003e\n\u003ctd\u003eHead Cover Type\u003c\/td\u003e\n\u003ctd\u003eN: Basic (integrated clevis)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003eAuto Switch Mounting Type\u003c\/td\u003e\n\u003ctd\u003eB: Band mounting\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.
