About the Airtac SAI50 Standard Cylinder SAI50X200S
The AirTAC SAI50X200-S is a double-acting profile cylinder with a 50mm bore and 200mm stroke, delivering a push force of 982 N at 0.5 MPa. Its extruded aluminum barrel lacks tie rods, presenting a clean exterior that speeds up machine cleaning and reduces contamination traps.
This variant includes a magnetic piston for use with CMSE or DMSE reed switches, enabling precise end-of-stroke detection. The standard carbon steel piston rod offers excellent wear resistance for general industrial automation.

Where the Airtac SAI50 Standard Cylinder SAI50X200S Is Used
Component Clamping
Provides 982 N of clamping force at 0.5 MPa to secure metal workpieces for machining or welding operations.
Package Diverting
The 200mm stroke extends pop-up arms or gates to redirect packages on automated sorting conveyor lines.
Gate Control
Actuates safety gates or process doors, using the magnetic piston to confirm closed positions via sensors.
Is the Airtac SAI50 Standard Cylinder SAI50X200S the Right Cylinder?
Choose this 50mm bore when an application requires around 982 N of push force at 0.5 MPa, sitting neatly between the 40mm bore (628 N) and the 63mm bore (1559 N). The 200mm stroke is well within the 1200mm maximum standard stroke for this size, so it is a standard stroke for this bore.
Because the stroke is 200mm, side-load bending on the rod bearing is minimal, but always verify the load is guided if pushing off-center. If the machinery loses air pressure, this cylinder cannot hold its load in place; for position holding without live pressure, consider the SAIL locking variant. This unit uses PT tapered ports and is dimensionally interchangeable per ISO 15552.
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.
