About the Airtac SAI50 Standard Cylinder SAI50AX120S
The AirTAC SAI50X120-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 120 mm stroke provides the exact mid-range travel needed for compact clamping and lifting tasks. The extruded aluminum barrel design omits tie-rods, ensuring a clean exterior that drops directly into standard ISO 15552 mounting footprints.
This specific configuration includes a magnet (-S) for proximity sensing and utilizes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. Sensors mount seamlessly into the dual-side switch grooves. It features PT tapered port threads and adjustable air cushions at both ends to decelerate the piston smoothly.

Where the Airtac SAI50 Standard Cylinder SAI50AX120S Is Used
Mid-Force Clamping
Secures medium-sized metal or plastic components during machining, utilizing 982 N of thrust at 0.5 MPa for rigid holding.
Package Diverting
Actuates routing gates on packaging lines where a 120 mm stroke pushes cartons smoothly onto secondary tracks.
Vertical Lifting
Elevates workpieces or pallet stops in automated assembly cells, using the integrated magnet to confirm up/down positions.
Is the Airtac SAI50 Standard Cylinder SAI50AX120S the Right Cylinder?
Select this 50 mm bore when an application requires more power than a 40 mm cylinder (which provides 628 N at 0.5 MPa) but lacks the physical space for a 63 mm unit. The 120 mm stroke is a non-standard intermediate length, useful when 100 mm is too short and 125 mm is too long. Because the stroke is under 300 mm, side-load stress on the rod bearing remains minimal for standard loads.
This cylinder relies on continuous air pressure to move and hold its position; it will drift if pressure is lost. For applications requiring true load holding upon exhaust, consider the SAIL variant with an air-released lock or the BSAI clamp-lock cylinder. To replace an existing unit, match the 50 mm bore, 120 mm stroke, PT G1/4 port, and mounting accessories like FA or LB.
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 SAI50AX120S FAQ
At 0.5 MPa operating pressure, this cylinder provides 982 N of push force and 825 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 1374 N.
Yes. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke. Ensure you match the G1/4 port and mounting accessories.
