SMC Corporation NCY3B15-3800 Rodless Cylinder

The SMC NCY3B15-3800 Rodless Cylinder is a magnetically coupled, double-acting actuator that delivers long-travel linear motion without a traditional drive rod, using magnets in the piston and external carriage to transfer movement. It features a 15 mm bore and a 38-inch stroke, and is rated for up to 100 psi (0.7 MPa) of operating pressure. A 10-32 threaded feature is listed for mounting interfaces, enabling straightforward integration with fixtures or tooling on automation lines. This cylinder’s magnetically coupled design minimizes through-rod obstruction while maintaining precise alignment between the internal piston and external carriage, making it well suited to long-stroke positioning, conveyor and fixture actuation, and other applications where a rodless solution saves space and reduces assembly complexity. With its standard basic-type configuration, the NCY3B15-3800 supports reliable, repeatable motion in industrial environments where extended travel and compact form factor are important.
