SMC Corporation US6391 Pneumatic Air Cylinder

SMC US6391 Pneumatic Air Cylinder is a compact linear actuator from SMC that converts compressed air into precise, straight-line motion for automated systems. As part of SMC’s broad lineup of standard air cylinders, it is designed for repeatable actuation in manufacturing tasks such as part transfer, clamping, and positioning in tight or confined spaces. Cylinders in the US6391 family are typically offered in a range of bore sizes and stroke lengths and support multiple mounting configurations to fit diverse fixtures and machine layouts; they are compatible with SMC mounting brackets, end fittings, and other common pneumatic accessories to streamline integration with valves and regulators. In practice, engineers consider bore diameter for force, stroke length for travel, and serviceable connection points when selecting a cylinder for a given application, with the brand’s catalogs and distributor data emphasizing reliable piston motion and straightforward installation. For exact specifications—bore, stroke, rod end type, mounting style, and compatible accessories—for US6391, refer to the official SMC product documentation or authorized distributor listings that reproduce the exact model variant.
