The SMC CDUK20-15D is a compact free-mount pneumatic cylinder from the SMC CU series engineered for precision linear motion control in industrial automation systems. Designed with a non-rotating rod mechanism and compact rectangular body, the cylinder allows direct multi-surface mounting without requiring additional brackets, helping reduce installation space in machinery and automation assemblies. Featuring a 20mm bore and 15mm stroke, the cylinder operates using double-acting pneumatic motion with built-in magnet capability for auto-switch integration. Its lightweight aluminum construction, rubber bumper cushioning, and stable piston guidance make it suitable for compact machinery, pick-and-place systems, packaging equipment, semiconductor machinery, and industrial automation applications requiring reliable and precise pneumatic actuation.
