Specification

SEODescription

The FESTO QST-1/4-8-50 Pneumatic Cylinder is a compact, high-performance actuator designed for precision motion control in industrial automation. With a bore size of 1/4" (8 mm) and a 50 mm stroke, it operates within a pressure range of 2–8 bar, ensuring reliable force output. This FESTO Compact Cylinder supports direct mounting via standardized ISO interfaces and integrates seamlessly with pneumatic systems using G1/4 threaded ports. It operates efficiently in temperatures from -10°C to +80°C, making it suitable for manufacturing, packaging, and assembly applications. Key advantages include its space-saving design, corrosion-resistant aluminum construction, and low friction for energy efficiency. Limitations include limited stroke customization and dependency on clean, dry compressed air. Ideal for applications requiring fast, repeatable linear motion.
