SMC Corporation NCY3B15-0138-DUS01890 Rodless Cylinder

SMC NCY3B15-0138-DUS01890 is a magnetically coupled, rodless cylinder (basic type) from SMC’s NCY3B family, delivering a compact 15 mm bore and a 138 mm stroke. In this design, magnets embedded in the piston and an external carriage provide the drive via magnetic coupling, allowing the external carriage to travel along the cylinder without a piston rod extending out. Powered by compressed air, the internal magnet assembly and external carriage stay synchronized along the cylinder’s length, enabling smooth linear motion in tight spaces. The NCY3B series is intended for automation tasks requiring space-efficient, reliable linear actuation and straightforward integration with standard pneumatic controls. This model’s bore and stroke specifications—15 mm bore, 138 mm stroke—define its compact footprint and travel length, making it suitable for constrained packaging equipment and guided positioning on compact automation lines where a conventional rod-type actuator would be impractical.
