About the Airtac SAI50 Standard Cylinder SAI50X5S
The AirTAC SAI50X5-S is a double-acting ISO 15552 profile cylinder engineered for micro-movements, delivering a robust 982 N of push force at 0.5 MPa despite its 5 mm stroke. Its extruded aluminum barrel omits tie rods, presenting a clean exterior that drops directly into standardized ISO 15552 mounting interfaces. This specific configuration includes a magnet for position sensing and utilizes carbon steel for the piston rod.
Because this is an -S variant, it readily accommodates CMSE or DMSE series reed switches via the integrated sensor grooves on both sides of the barrel. For environments requiring elevated thermal resistance, the standard TPU seals can be swapped for Viton (H) alternatives, extending operational reliability up to the standard +70 C limit and beyond in custom builds.

Where the Airtac SAI50 Standard Cylinder SAI50X5S Is Used
Short-Stroke Clamping
Ideal for holding thin workpieces securely in machining or assembly fixtures without overextending into the work area.
Product Ejection
Delivers a rapid 5 mm punch to nudge lightweight components off a conveyor belt into a downstream packaging chute.
Valve Actuation
Provides the precise linear displacement needed to toggle small mechanical valves or trigger micro-switches in automated machinery.
Is the Airtac SAI50 Standard Cylinder SAI50X5S the Right Cylinder?
Selecting this 5 mm stroke is optimal when the application demands a short, decisive jab rather than a full extension, such as clamping or ejecting. If your process requires less impact energy, stepping down to a 40 mm bore drops the 0.5 MPa push force to 628 N. Conversely, upgrading to a 63 mm bore raises that output to 1559 N.
Since this is a non-standard 5 mm stroke, ensure your control system relies on internal mechanical stops or external limiters if precise end-of-stroke positioning is critical. This standard double-acting cylinder relies on live air pressure to maintain its state; if your workflow cannot tolerate drift during a compressed air failure, consider the SAIL variant with its integrated air-released lock. The PT tapered porting ensures a tight, reliable seal for your pneumatic fittings.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI50 Standard Cylinder SAI50X5S FAQ
At a standard operating pressure of 0.5 MPa, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. It can reach up to 1374 N of push force at 0.7 MPa.
Yes, the SAI50X5-S is dimensionally interchangeable per ISO 15552 standards. You can drop it directly into existing foot, flange, or trunnion mounts designed for equivalent ISO 15552 profile cylinders.
