SMC 11-CDG1BA50-140Z | Clean Room Air Cylinder CG1 Series 50mm Bore 140mm Stroke Double-Acting Single Rod Round Body

The SMC 11-CDG1BA50-140Z is a clean room specification air cylinder from the CG1 series, configured as a double-acting single rod round body type. Part number decoded: CDG1 = CG1 series with D (double acting), B = basic type, A = band mounting or specific mount style, 50 = 50mm bore diameter, 140 = 140mm stroke length, Z = clean room specification with auto-switch groove. The 11- prefix indicates an enhanced clean room grade (Grade 2 or similar specification level different from the 10- prefix).

The CG1 series is SMC's standard round body profile air cylinder, distinct from the CQ2 compact square body and the CM2 standard tie-rod designs. The round body construction provides inherent structural rigidity and accommodates a wide range of mounting accessories (foot brackets, flange mounts, trunnion mounts, clevis brackets) that attach to the cylindrical barrel. The 50mm bore generates approximately 118N of force at 0.6 MPa, suitable for medium-duty clean room automation tasks including material handling, pressing operations, and assembly fixture actuation.

The CDG1BA50-140Z provides a 140mm stroke — a non-standard length that suggests a custom or application-specific travel requirement. For standard 50mm bore CG1 variants with different strokes, the series offers increments from short to long travel. For compact mounting at 50mm bore, the CQ2B50 compact cylinder provides a shorter overall length. For guided motion, the MGF series guide table provides anti-rotation. The CG1 series accepts D-series auto switches in the Z groove. Clean series (11-) fluorine grease. RoHS compliant.
