SMC CDG1BN20100Z (CDG1BN20-100Z) - Round Body Air Cylinder, 20 mm Bore, 100 mm Stroke
SMC CDG1BN20100Z Round Body Air Cylinder — 20 mm bore, 100 mm stroke, rubber bumper, basic mount, built-in magnet. SMC CG1 Series (CG1-Z) round body air cylinder, double acting, single rod, with built-in magnet (CDG1) for auto switch mounting. Per the official SMC how-to-order the code reads CDG1 + mounting + cushion + bore - stroke + Z: B = basic mounting, N = rubber bumper (A = air cushion), 20 = 20 mm bore, 100 = 100 mm stroke, and the trailing Z is the fixed series suffix of the current CG1-Z generation (it is not a selectable option in the how-to-order). Male rod end (Nil); rod end nut supplied as standard. 100 mm is a standard stroke for the 20 mm bore (25, 50, 75, 100, 125, 150, 200 mm). Fluid: air. Proof pressure 1.5 MPa, maximum operating pressure 1.0 MPa, minimum operating pressure 0.05 MPa. Ambient and fluid temperature -10 to 70 C without auto switch, -10 to 60 C with auto switch. Piston speed 50 to 1000 mm/s. Lubrication not required (non-lube). Allowable kinetic energy with rubber bumper, male rod end: 0.28 J.

CDG1BN20-100Z Applications
This CG1 round body cylinder is a compact general-purpose actuator for pushing, clamping, lifting and part transfer on assembly, packaging and conveying machinery. The rubber bumper version is the standard low-cost choice for light loads and moderate speeds, absorbing the impact at each stroke end without the need to tune cushion needles. Basic mounting keeps the envelope small and lets brackets be added later, and the built-in magnet accepts SMC auto switches for end-of-stroke position feedback to the PLC.
