About the Airtac SAI50 Standard Cylinder SAI50AX700
The AirTAC SAI50X700 is a double-acting ISO 15552 profile cylinder engineered for a 700 mm stroke. It generates 982 N of push force and 825 N of pull force at 0.5 MPa, making it well-suited for mid-range linear actuation tasks.
This unit is configured with a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. It utilizes PT tapered port threads, and because it lacks the -S magnet option, it operates without integrated sensor grooves being active for reed switches.

Where the Airtac SAI50 Standard Cylinder SAI50AX700 Is Used
Long-Stroke Diversion
Pushes packages or pallets laterally across a conveyor belt over a 700 mm distance using 982 N of thrust at 0.5 MPa.
Vertical Material Lift
Raises lightweight trays or bins in automated storage systems, requiring external guidance to handle the extended rod length safely.
Door Actuation
Opens and closes large industrial machine safety doors or heavy gates where a long 700 mm travel distance is necessary.
Is the Airtac SAI50 Standard Cylinder SAI50AX700 the Right Cylinder?
When specifying this actuator, consider that a 700 mm stroke creates a long extension, which can subject the rod bearing to significant bending stress under side loads. Implementing an external guide rail or choosing a guided cylinder design is strongly recommended to prevent premature wear.
If your application requires less force, stepping down to a 40 mm bore yields 628 N at 0.5 MPa, while upgrading to a 63 mm bore provides 1559 N. Because this is a standard double-acting cylinder, it cannot hold a load if air pressure drops; use the SAIL variant with an air-released lock for fail-safe positioning. This model serves as a dimensionally interchangeable direct replacement for other ISO 15552 profile cylinders, matching the 50 mm bore, 700 mm stroke, PT port, and standard mounting accessories like the FA flange.
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 SAI50AX700 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides a push force of 982 N and a pull force of 825 N. If pressure is increased to 0.7 MPa, the push force rises to 1374 N.
Yes, it is built to the ISO 15552 standard, making its mounting dimensions fully interchangeable with other ISO 15552 profile cylinders of the same 50 mm bore and 700 mm stroke. Always confirm that your port and accessory match.
