SMC 10-CDG1BN20-75Z | 10-/11-CG1-Z Series Clean Room Air Cylinder Double Acting Single Rod 20mm Bore 75mm Stroke Round Body

The SMC 10-CDG1BN20-75Z is a clean room specification round body air cylinder from the 10-/11-CG1-Z series, configured with a compact 20mm bore and 75mm stroke for smaller-force clean room actuation applications. The 20mm bore generates lower actuation force compared to larger bore variants, making this cylinder ideal for light-duty positioning, small component handling, door and cover mechanisms, and any clean room application requiring moderate force with compact envelope dimensions.

How does the "N" rod end differ from "A" in the CG1 series? The "N" designation in the CG1 part number indicates a specific rod end and port configuration within the series options. Rod end and port variations allow engineers to match the cylinder interface to the mechanical design requirements of the target equipment without external adapters. The part number decode follows: "CDG1" (cushioned CG1), "B" (basic mounting), "N" (rod end type), "20" (bore mm), "75" (stroke mm), "-Z" (special specification).

The "10-" clean series specification provides fluorine grease lubrication, controlled clean room assembly, and anti-static double packaging for particle generation grade 1 performance. This ensures the cylinder itself does not contribute contaminants to the clean room atmosphere during operation, which is particularly important for actuators with exposed rod seals that could shed particles during cycling.

This cylinder is RoHS compliant and designed for integration into clean room pneumatic systems. Compatible with SMC auto-switches for position detection and clean series speed controllers for precise speed regulation.
