Festo DSNU-S-8-100-P-A-MQ – Compact Stainless Steel Round Cylinder, Bore 8 mm, Stroke 100 mm

The DSNU-S-8-100-P-A-MQ is a miniature double-acting round cylinder from Festo's DSNU-S series — the stainless steel variant of the well-established DSNU round cylinder family. With an 8 mm piston diameter and 100 mm stroke, this cylinder is engineered for space-restricted automation where cleanliness, corrosion resistance, and repeatable linear force are non-negotiable. The stainless steel barrel and piston rod, combined with its Class 5 cleanroom suitability (ISO 14644-1), make it a first-choice component for pharmaceutical, food processing, and precision assembly applications across Coimbatore and the wider South Indian industrial belt.

Key Features

• High-alloy stainless steel cylinder barrel and piston rod — delivers reliable performance in wet, washdown, and mildly corrosive environments without surface degradation over time.
• Cleanroom Class 5 suitability (ISO 14644-14) — independently measured and certified, making this cylinder suitable for pharmaceutical manufacturing, medical device assembly, and sensitive electronics automation.
• Double-acting operation — provides positive force in both advance and return strokes (30.2 N advance / 22.6 N return at 6 bar), giving full control over both directions of movement.
• Elastic end-position cushioning at both ends — reduces mechanical shock at stroke limits, extending service life of the cylinder and the connected tooling or fixture.
• M5 pneumatic connection — compact port size that integrates cleanly with miniature push-in fittings and small-bore tubing commonly used in tight multi-axis assemblies.
• M4 piston rod thread — standard metric thread for straightforward mounting of jaw grippers, guide rods, brackets, or custom tooling without adapters.
• Wide operating pressure range: 1.5 to 10 bar (0.15–1 MPa) — compatible with standard factory compressed air networks, no pressure regulation typically required for most applications.
• Wide ambient temperature range: –20 °C to +80 °C — functions reliably from cold-room environments to hot press and oven-adjacent automation without seal degradation.
• LABS (PWIS) conformity per VDMA 24364-B2-L — important for automotive paint shops and surface-finish-critical environments where silicone contamination must be excluded.
• RoHS compliant construction — meets European and international hazardous substance restrictions for export-oriented manufacturers and OEMs.

Technical Specifications

Common Applications

• Pharmaceutical and medical device manufacturing — cleanroom Class 5 rating makes it directly applicable to tablet press tooling, vial handling, and sterile filling line actuators in regulated production environments.
• Food and beverage packaging lines — stainless steel construction and LABS-conformant materials suit washdown-zone actuators on form-fill-seal machines, portion dispensers, and product ejectors.
• Precision assembly automation — small bore and compact length allow integration into multi-axis pick-and-place heads, PCB handling grippers, and micro-component insertion fixtures.
• Textile machinery — used in yarn tensioner actuators, thread cutter mechanisms, and bobbin-change indexing systems on weaving and winding machines common in the Coimbatore textile cluster.
• Plastic injection moulding ancillary automation — gate cut-off, sprue picker, and side-core actuator duties where cycle-life and contamination control matter.
• Laboratory and analytical instrument automation — low moving mass and predictable force output support valve actuation and sample handling in scientific instruments.

Compatible Accessories

• Mounting brackets and clevis mounts — Festo DSNU-S series foot brackets, flange mounts, and swivel mounts for fixed and pivot installations.
• Proximity switches and magnetic sensors — SME/SMT series sensors for piston position detection through the cylinder barrel (specify slot type compatible with DSNU-S).
• M5 push-in fittings (QS-M5 series) — for 4 mm OD tubing connections; quick, tool-free installation on the pneumatic ports.
• 4 mm OD polyurethane or nylon tubing — compatible with M5 push-in fittings; available in cut lengths or standard coil lengths.
• Flow control valves (GRLA-M5 series) — for meter-out speed control on advance and return strokes, essential when controlling light payloads at higher pressures.
• Thread sealant / PTFE tape — recommended for M5 port connections where direct-thread fittings are used instead of push-in types.
