Stainless steel cylinder
Piston rod cylinder
Festo stainless steel cylinders of the CRDSNU-B series are corrosion-resistant round cylinders to ISO 6432 with a stainless steel housing. The range covers 45 items in bore diameters from 16 to 32 mm with strokes from 10 to 200 mm. The prefix CR stands for Corrosion Resistant; the housing, piston rod and external surfaces are made of stainless steel (suffix -B), making these cylinders suitable for aggressive media, cleanroom applications, and hygiene areas with CIP/SIP cleaning.
All available variants carry the suffix -PPS-A (bilateral end cushioning, magnetic piston) in the standard form, or -P-A for smaller bores. The connection geometry conforms to ISO 6432, allowing replacement of standard DSNU cylinders without design changes.
| Type | Bore Ø | Stroke | Cushioning |
|---|---|---|---|
| CRDSNU-B-16-...-P-A-MG-A1 | 16 mm | 10-125 mm | Bilateral, magnetic piston |
| CRDSNU-B-25-...-PPS-A-MG-A1 | 25 mm | 10-200 mm | Bilateral, magnetic piston |
| CRDSNU-B-32-...-PPS-A-MG-A1 | 32 mm | 10-200 mm | Bilateral, magnetic piston |
Typical applications: Food and beverage industry with cleaning requirements (CIP/SIP), pharmaceutical manufacturing and cleanroom facilities, chemical process engineering with corrosive atmospheres, offshore and marine environments, and applications where ISO 6432 standard dimensions must be combined with enhanced corrosion resistance.
