{"product_id":"cd85n2540b","title":"SMC CD85N2540B (CD85N25-40-B) - Mini Air Cylinder, 25mm Bore, 40mm Stroke","description":"\u003cp\u003eSMC CD85N2540B Mini Air Cylinder — 25 mm bore, 40 mm stroke, rubber bumper, band-mount auto switch type. SMC CD85N25-40-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. No C suffix is present, so the cylinder uses the standard rubber bumper rather than air cushion, and the B suffix specifies band-type auto switch mounting. 40 mm is a listed standard stroke for the 25 mm bore 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 0.4 J with rubber bumper, 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 CD85N25-40-B · \u003cstrong\u003eSKU:\u003c\/strong\u003e CD85N2540B\u003c\/p\u003e\u003ch2\u003eCD85N25-40-B Applications\u003c\/h2\u003e\u003cp\u003eA compact 40 mm stroke covers short-travel clamping, stopping, ejecting and indexing tasks on assembly jigs, packaging machines and small conveyors. The rubber bumper suits moderate speeds and light kinetic loads while keeping the cylinder short and inexpensive. The slim ISO 6432 round body fits crowded machine frames, and the integrated clevis head cover eases pivoting installations. The built-in magnet lets band-mounted auto switches confirm rod position for interlocks and PLC step sequencing.\u003c\/p\u003e\u003ch2\u003eCD85N25-40-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\u003eCD85N25-40-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\u003eRubber bumper (standard)\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.
