CDG1BN40-25Z Applications
A short stroke, high thrust round body cylinder well suited to clamping, pressing, marking and locating tasks where only 25 mm of travel is needed but a 40 mm bore is required for force. The compact overall length lets it be fitted inside tight tooling and fixture assemblies. The built-in magnet allows D-M9 series auto switches to be clamped on the barrel for clamp confirm signals, and the rubber bumper limits impact noise on rapid cycling.
