SMC CDG1BN2050Z (CDG1BN20-50Z) - Round Body Air Cylinder, 20mm Bore, 50mm Stroke
SMC CDG1BN2050Z Round Body Air Cylinder — 20mm Bore, 50mm Stroke. SMC CDG1BN20-50Z is a CG1-Z series round body air cylinder with a 20 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 M8 x 1.25 with a 8 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.

CDG1BN20-50Z Applications
Use this compact 20 mm bore CG1 cylinder for short 50 mm push, pull, clamp, lift and transfer moves on packaging lines, small assembly jigs, indexing stations and material handling gates. The built-in magnet lets auto switches be clamped anywhere along the round tube for end-of-stroke position sensing without extra brackets, while the rubber bumper absorbs impact at both ends. Its light, non-lube aluminium body suits high-cycle machines where a small footprint and low break-away pressure matter.
