About the Airtac SAI50 Standard Cylinder SAI50X700STC
The AirTAC SAI50X700-S is a double-acting ISO 15552 profile cylinder engineered for long-trroke automation tasks. It delivers a push force of 982 N and a pull force of 825 N at 0.5 MPa, making it well-suited for moving moderate loads over extended distances. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies cleaning and sensor placement.
Equipped with a magnetic piston (-S), this unit supports CMSE and DMSE position switches via sensor grooves on both sides of the barrel. It features a standard carbon steel piston rod and a PT tapered port thread. For environments requiring higher heat resistance, the standard TPU seals can be swapped for Viton (H) or NBR (N) options to match specific operational demands.

Where the Airtac SAI50 Standard Cylinder SAI50X700STC Is Used
Long-Stroke Material Transfer
Pushes products or pallets between distant workstations on a conveyor line, utilizing the full 700 mm stroke to bridge large machine gaps.
High-Bay Carton Pushing
Actuates sorting arms or pushing mechanisms in packaging facilities where 982 N of thrust is sufficient to move moderate cardboard loads.
Large Door Actuation
Opens and closes heavy machine safety doors or equipment panels, relying on the magnetic piston for precise mid-stroke position feedback.
Is the Airtac SAI50 Standard Cylinder SAI50X700STC the Right Cylinder?
Selecting this 50 mm bore cylinder makes sense when a 40 mm bore (offering 628 N push at 0.5 MPa) lacks the necessary thrust, but a 63 mm bore (1559 N) would be physically oversized. At a 700 mm stroke, the extended rod is highly susceptible to bending under side loads. To prevent premature seal wear and rod-bearing failure, pair this cylinder with an external guide rail or use a dedicated guided cylinder to absorb lateral forces.
This model is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other standard profile cylinders. To match your existing setup, specify the PT port thread, TC trunnion mounting accessory, and ensure the -S magnet option is included for electronic position sensing. Note that the adjustable air cushions only decelerate the piston at stroke ends; if the air supply is lost, the load will drift. Use a SAIL variant or external pilot-operated check valve for position 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 SAI50X700STC FAQ
At an operating pressure of 0.5 MPa, 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, the SAI50X700-S is built to ISO 15552 mounting interface standards, making it dimensionally interchangeable with other ISO 15552 profile cylinders. Ensure you match the TC trunnion mount, PT port, and 700 mm stroke during installation.
