SMC CDG1BN2550Z (CDG1BN25-50Z) - Round Body Air Cylinder, 25mm Bore, 50mm Stroke
SMC CDG1BN2550Z Round Body Air Cylinder — 25mm Bore, 50mm Stroke. SMC CDG1BN25-50Z is a CG1-Z series round body air cylinder with a 25 mm bore and 50 mm stroke. It is a double acting, single rod actuator with a built-in magnet (CDG1 prefix) so that SMC auto switches can be mounted directly on the round tube. The 'B' code denotes the basic mounting style and the 'N' code denotes rubber bumper cushioning. The impact-extruded aluminium tube and rod cover are hard anodised, and the piston rod is stainless steel on the magnet-equipped 20 mm and 25 mm bore sizes. It runs on air, requires no lubrication (non-lube), operates from 0.05 MPa up to a maximum of 1.0 MPa with a 1.5 MPa proof pressure, and uses Rc 1/8 ports. Rod end is male thread M10 x 1.25 with a 10 mm diameter piston rod. Ambient and fluid temperature range is -10 to 70 C without an auto switch, or -10 to 60 C with an auto switch fitted.

CDG1BN25-50Z Applications
This 25 mm bore, 50 mm stroke CG1 cylinder is a workhorse for clamping, pressing, feeding and stopper duties on assembly and packaging machines. The round aluminium tube houses a built-in magnet so auto switches can be positioned anywhere along the barrel for extend and retract sensing without extra hardware. Rubber bumper cushioning handles end-of-stroke impact, and non-lube operation with a basic mount and male M10 rod end simplifies installation and replacement.
