Product Description
About the Festo DSNU-S-8-10-P-A-MQ Round Cylinder
The DSNU-S-8-10-P-A-MQ is part of Festo's DSNU-S series — a stainless-steel variant of the well-established ISO 6432 round cylinder family, purpose-built for environments where standard aluminium construction is not adequate. With an 8mm bore and 10mm stroke, this is one of the smallest members of the range, delivering a precise 30.2 N advance force at 6 bar in an extremely compact envelope. The stainless cylinder barrel and piston rod, combined with ISO Class 5 cleanroom suitability and LABS (PWIS) conformity, make this cylinder a reliable choice wherever product contamination must be eliminated and surface cleanliness is non-negotiable.Key Features
- Stainless steel cylinder barrel and piston rod — provides genuine corrosion resistance (CRC 2) for wash-down environments, humid process areas, and hygienic machinery without needing additional protective coatings.
- ISO Class 5 cleanroom suitability (ISO 14644-14) — independently tested and rated for cleanroom deployment; ideal for pharmaceutical packaging, medical device assembly, and semiconductor handling.
- LABS/PWIS conformity to VDMA 24364-B2-L — no paint-wetting impairment substances; essential for automotive body-in-white and paint-finish adjacent applications.
- Double-acting operation — positive pneumatic force in both directions gives reliable, repeatable motion without relying on a return spring, improving cycle consistency.
- M5 push-in (MQ) pneumatic connection — direct push-in port eliminates the need for separate fittings on the cylinder body, reducing assembly time and potential leak points on compact machine layouts.
- Elastic cushioning rings at both ends — absorbs end-of-stroke impact energy (0.03 J rated), extending service life even at higher cycle rates without requiring adjustable needle cushioning.
- Wide operating temperature range: –20 °C to +80 °C — suitable for cold-store conveyor systems as well as warm process environments without seal degradation.
- Any mounting position — no orientation constraint simplifies machine design; mount horizontally, vertically, or at any angle without affecting performance.
- Proximity switch compatible — cylinder body is designed for standard Festo proximity switch mounting, enabling position feedback without modifying the cylinder.
- RoHS compliant — meets EU and UK RoHS requirements, supporting compliance documentation for machine builders exporting to European markets.

Common Applications
- Pharmaceutical and medical device packaging — cleanroom Class 5 rating and stainless construction suit blister-pack indexing, vial handling, and syringe assembly lines where contamination control is mandatory.
- Food and beverage processing machinery — stainless steel barrel and rod withstand wash-down cleaning cycles on packaging conveyors and filling machines in food-grade production areas.
- Precision pick-and-place on PCB and electronics assembly — short 10mm stroke and low moving mass allow fast, repeatable micro-actuation on SMT component placement fixtures.
- Textile machinery in Coimbatore spinning mills — compact bore suits thread-tensioning and small gripper actuators on ring frames and winding machines where installation space is minimal.
- Laboratory and analytical instrumentation — low weight, cleanroom suitability, and M5 push-in port allow integration into compact bench-top test rigs and automated sampling equipment.
- Plastic injection moulding ejector and gate systems — double-acting action provides positive pin ejection and return, while stainless construction handles mould-release chemical exposure.
