SMC Corporation MRQBS40-25CB-XN Pneumatic Cylinder

MRQBS40-25CB-XN is a rotary actuator from SMC’s MRQ series that integrates a 40 mm bore with a 25 mm linear stroke to provide 180° of rotation alongside linear motion in a compact package. Suitable for pick-and-place and part-orientation tasks, it can be combined with SMC grippers to transfer and rotate parts in a single cycle on automated lines. The unit uses Rc port connections on both ends with a dedicated rotating port for the rotary section, and it includes a magnet for sensing. Mounting is described as basic, typically via four screws, and the shaft is single; weighing about 5.0 lb, this MRQ model fits MRQ’s 5–100 mm stroke range and 40 mm bore, enabling stable, repetitive positioning across a wide range of applications, including automated assembly, packaging, and electronics-handling tasks where orientation matters.
