SMC CDQ2B12525DCZ (CDQ2B125-25DCZ) - Compact Air Cylinder, 125 mm Bore, 25 mm Stroke

SMC CDQ2B12525DCZ Compact Air Cylinder — 125 mm LARGE BORE, 25 mm stroke, double acting single rod, rubber bumper (C), Rc port, built-in magnet, Z groove on 4 surfaces. SMC CQ2-Z Series compact air cylinder, LARGE BORE SIZE type, double acting, single rod. Parsing note: the compressed part number CDQ2B12525DCZ resolves to CDQ2B125-25DCZ, i.e. 125 mm bore with 25 mm stroke (125 is a valid CQ2 large bore; the large bore range is 125, 140, 160, 180, 200 mm). Verified on the SMC WEB Catalog: 'CQ2 Z Series Compact Cylinder: Large Bore Size Type Double Acting, Single Rod', Bore Size 125 (125 mm), Port Thread Type blank = Rc, Cylinder Stroke 25, Body Option blank = standard rod end female thread, Auto Switch Mounting Groove Z = 4 surfaces, without auto switch, D = built-in magnet. In the large bore how-to-order the suffix 'DC' is Action D (double acting) plus Cushion C (rubber bumper, standard on the large bore type) - it is not a body option. Official large bore specifications: fluid air; proof pressure 1.5 MPa; maximum operating pressure 1.0 MPa; minimum operating pressure 0.05 MPa; piston speed 50 to 500 mm/s; cushion rubber bumper (standard); mounting through-hole / both ends tapped (common); port size Rc 3/8 for the 125 mm bore; ambient and fluid temperature -10 to 70 C without auto switch, -10 to 60 C with auto switch. Stroke note: the published large bore standard stroke table is 10, 20, 30, 40, 50, 75, 100, 125, 150, 175, 200, 250, 300 mm, so 25 mm is supplied as an intermediate stroke (SMC lists intermediate strokes from 5 to 295 mm for the 125-200 mm bores); the part number itself is accepted and decoded by the SMC WEB Catalog.

CDQ2B125-25DCZ Applications

Large bore compact cylinders deliver high thrust from a very short body, so they are used for heavy clamping, pressing, die and mould closing, lifting and jacking of heavy fixtures, and for hold-down duties on presses and welding jigs where headroom is scarce. At 125 mm bore the theoretical output is several kilonewtons at typical line pressure, while the 25 mm stroke suits short clamp or press strokes. The rubber bumper absorbs stroke-end impact, and switches drop into grooves on any of four faces.
