RMH series pneumatic rodless cylinder

Magnetically coupled rodless cylinder: There is no mechanical connection between the piston and the carriage, ensuring excellent sealing performance.
Piston movement is transmitted to the external carriage via magnetic coupling; the absence of a piston rod saves installation space and allows for a longer maximum stroke compared to standard cylinders.
Equipped with both adjustable and fixed cushioning at both ends, ensuring smooth, shock-free directional changes and preventing mechanical damage; external hydraulic shock absorbers can be ordered separately for enhanced cushioning performance.
The piston chamber is isolated from the carriage, preventing dust and debris from entering the system and extending the cylinder’s service life.
Features an integrated guide rail design, ensuring high operational precision, minimal non-rotating deviation, and strong load-bearing capacity.

RMH series pneumatic rodless cylinder is an integrated linear-guide, magnetically coupled rodless cylinder—a precision slide-type unit. It transmits power via a magnetic linkage between the internal piston’s permanent magnet and the external carriage. Featuring an integrated linear ball guide at the base, it offers high-precision guidance without the need for external rails. It combines the space-saving benefits and leak-free magnetic sealing of rodless cylinders while overcoming the limitations of the RMS series (which lacks guidance) and the RMT series (which has weak guide-rod rigidity). Designed for applications such as small-scale precision transfer, multi-point positioning, and stations involving lateral eccentric loads, it serves as a direct alternative to the SMC CY1S slide-type magnetically coupled rodless cylinder.

Air inlet and outlet are on the same side, facilitating piping.

Equipped with mounting grooves for sensors (magnetic switches).

Addition of a guide rail design: enhances the operating precision of the main body, improves non-rotating accuracy, and increases load-bearing capacity.

Magnetic-coupling rodless cylinder section: There is no mechanical connection between the piston and the slider, resulting in excellent sealing performance.

The pneumatic cylinder can be mounted in multiple orientations.

Capable of carrying loads from multiple direction
