The PRA series is Aventics' flagship ISO 15552 profile cylinder line, descended from the Rexroth Pneumatik product family. Aluminum extruded profile bodies cover bores from 32 mm through 320 mm with metric stroke options, integrated magnetic piston for sensing, and a full set of ISO-standard mounting kits. The PRA platform is a direct interchange for the global ISO 15552 footprint used across European machine designs and process pneumatics.
