About the Airtac SAI50 Standard Cylinder SAI50AX210S
The AirTAC SAI50X210-S is a double-acting ISO 15552 profile cylinder with a 50mm bore and 210mm stroke. It delivers a push force of 982 N at 0.5 MPa, making it well-suited for mid-range automation tasks requiring reliable linear motion.
This specific configuration includes an -S magnet for direct compatibility with CMSE and DMSE sensor switches, which seat neatly into the dual grooves on the extruded aluminum barrel. It is built with an SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads.

Where the Airtac SAI50 Standard Cylinder SAI50AX210S Is Used
Component Clamping
Secures machined metal parts during milling or drilling operations using its 982 N push force at 0.5 MPa.
Package Diverting
Actuates routing gates on packaging lines, utilizing the 210mm stroke to push cartons cleanly between belts.
Pallet Stopping
Controls the flow of pallets at assembly stations, absorbing kinetic energy with its adjustable air cushions.
Is the Airtac SAI50 Standard Cylinder SAI50AX210S the Right Cylinder?
Choose this 50mm bore when an application requires around 982 N of push force at 0.5 MPa. If your task needs less force, stepping down to a 40mm bore yields 628 N; if more power is necessary, moving up to a 63mm bore provides 1559 N.
Because the 210mm stroke exceeds 300mm is false here, but as a general rule for strokes approaching this length, be mindful of side loads. For this 210mm length, ensure the load is guided to prevent rod-bearing bending. This cylinder is dimensionally interchangeable per ISO 15552, accepting standard FA, FB, LB, CA, CB, and TC mounting accessories. Note that standard SAI cylinders drift when air pressure is lost; use a SAIL variant if the application requires a pneumatic lock to hold a load.
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 SAI50AX210S FAQ
At 0.5 MPa operating pressure, this 50mm bore cylinder provides a push force of 982 N and a pull force of 825 N. At 0.7 MPa, the push force increases to 1374 N.
Yes. The SAI50X210-S is a true ISO 15552 profile cylinder, meaning its mounting dimensions are interchangeable with other ISO 15552 cylinders. It serves as a direct replacement for matching 50mm bore and 210mm stroke profiles.
