A rodless cylinder with mechanical joining differs from a basic air cylinder in that no piston rod extends outside the cylinder body.  Instead, the internal piston is connected to an external carriage.  SMC's rodless cylinders are ideal for long stroke applications because they are unaffected by rod overhang, bending, piston binding, and uneven seal wear, and for use in confined areas where space is a premium.

The 25A- series variations are designed using material compatible with secondary battery applications and are able to be used in low dew point environments.  The variations eliminate copper (Cu) and zinc (Zn) material where possible, making them compatible with secondary battery manufacturing for electronics, automotive, and other vehicle types.
