SMC MY1B25-400 Pneumatic Rodless Guided Air Cylinder

SMC MY1B25-400 Pneumatic Rodless Guided Air Cylinder is a compact, long-stroke linear actuator with a 25 mm bore and a 400 mm stroke, featuring a rodless design with a sliding carriage that travels along an integrated guide (often used in slide-table configurations) for precise positioning across the full travel. It belongs to the MY1B family as a mechanically jointed, double-acting, basic-type cylinder that uses a one-piece carriage and piston, with an outer dust seal and an inner belt seal to maintain air pressure while protecting against contaminants. The standard configuration employs a basic guide (Standard Type) and a 1/8 BSPT air-port, with an operating pressure range typically from 14 to 116 psi (0.95–8.0 bar) and ambient temperature compatibility around 41–140°F, making it suitable for automation tasks that require extended travel in a compact footprint, such as assembling, aligning, or positioning components in fixtures and machines.
