SMC MY1B25G-400-Z73S Pneumatic Slide Cylinder

SMC MY1B25G-400-Z73S is a mechanically joined rodless pneumatic slide cylinder from SMC's MY1B series, delivering a compact 25 mm bore and a 400 mm stroke in a double-acting configuration. As a basic-type MY1B cylinder, it uses a guided slider with a simple mounting interface and an air-cushioned travel path to reduce impact and wear. The MY1B family is documented in SMC data sheets as offering bores of Ø25, Ø32, and Ø40 with stroke options including 100, 200, 300, 400, 500, 600, 700, and longer lengths in certain configurations. The 25×400 configuration is a representative example of the MY1B basic type with a rodless design intended for compact linear actuation in automated equipment. This combination of features—rodless construction, double-acting operation, and air cushioning—provides smooth, repeatable motion in confined spaces where a traditional piston cylinder would be impractical.
