About the Airtac SAI50 Standard Cylinder SAI50X220S
The AirTAC SAI50X220-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 220mm stroke. It delivers a robust 982N push force and 825N pull force at 0.5 MPa, making it well-suited for mid-range industrial motion tasks. The extruded aluminum barrel design eliminates tie rods, providing a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
Equipped with a magnetic piston (-S), this specific model is fully compatible with CMSE and DMSE series sensor switches. The integrated sensor grooves on both sides of the profile barrel allow for highly flexible switch mounting along the stroke. Standard configuration includes a carbon steel piston rod and PT tapered port threads for secure, leak-free pneumatic connections.

Where the Airtac SAI50 Standard Cylinder SAI50X220S Is Used
Package Sorting
Provides reliable 220mm linear movement to push or divert packages on high-speed material handling lines.
Clamping Fixtures
Generates up to 982N of clamping force at 0.5 MPa for holding workpieces securely during machining operations.
Gate Control
Actuates safety gates or heavy access doors with smooth deceleration provided by the adjustable end cushions.
Is the Airtac SAI50 Standard Cylinder SAI50X220S the Right Cylinder?
When specifying this actuator, verify if the 982N thrust at 0.5 MPa provides adequate safety margin for your load; stepping up to the 63mm bore yields 1559N if higher force is required. Conversely, a 40mm bore provides 628N for lighter payloads. The 220mm stroke is a standard length and falls well within the 1200mm maximum for this bore, ensuring optimal operating speeds of 30-800 mm/s.
Because the stroke exceeds 300mm, be mindful of side-load stresses on the rod bearing. For applications involving heavy off-center loads, utilize an external guide rail or select a guided cylinder to prevent premature wear. Note that the adjustable air cushions at both ends decelerate the piston near stroke end but do not lock the load; if position holding without air pressure is required, consider the SAIL variant or an external rod lock.
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.
