About the Airtac SAI50 Standard Cylinder SAI50AX200S
The AirTAC SAI50X200-S is a double-acting ISO 15552 profile cylinder offering a 50mm bore and 200mm stroke. It generates 982N of push force and 825N of pull force at 0.5 MPa, making it well-suited for medium-duty handling tasks.
This variant includes a magnet for proximity sensing and uses a SUS420J2 stainless steel piston rod (option A) for enhanced durability against moisture. The extruded aluminum barrel features sensor grooves on both sides for CMSE and DMSE switches, and the PT tapered port threads ensure a robust, leak-free pneumatic connection.

Where the Airtac SAI50 Standard Cylinder SAI50AX200S Is Used
Package Diverting
Provides the 982N push force needed to reliably divert medium-weight packages on a sorting line.
Clamping Fixtures
Holds workpieces securely in place during light machining or assembly operations using its 200mm stroke.
Material Handling
Ideal for lifting and positioning pallets or totes where a magnet-equipped cylinder is required for end-of-stroke detection.
Is the Airtac SAI50 Standard Cylinder SAI50AX200S the Right Cylinder?
If your application requires less force, stepping down to a 40mm bore yields 628N at 0.5 MPa; conversely, a 63mm bore provides 1559N for heavier payloads. Because this 200mm stroke is under the 300mm threshold, side-load bending is less severe, but you should still ensure proper rod-bearing alignment to prevent premature wear.
For a direct replacement, match the 50mm bore, 200mm stroke, G1/4 port, and desired mounting accessory (like FA flange or TC trunnion). Remember that this standard cylinder relies on live air pressure to hold its position; if power fails, the piston drifts. Use the SAIL variant with an air-released lock for fail-safe load holding.
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 SAI50AX200S FAQ
