About the Airtac SAI50 Standard Cylinder SAI50X800S
The AirTAC SAI50X800-S is a double-acting ISO 15552 profile cylinder engineered to deliver a push force of 982 N at 0.5 MPa. Featuring an 800 mm stroke, it is purpose-built for extended-travel automation tasks requiring substantial linear displacement. The extruded aluminum barrel design omits tie rods, providing a clean exterior that resists mechanical fouling.
This specific configuration includes a standard carbon steel piston rod and a built-in magnet (-S) for seamless integration with CMSE or DMSE reed switches via the dual sensor grooves machined into the barrel. Fluid compatibility is restricted to filtered air, and the standard TPU seals support an operating temperature range of -20 to +70 C.

Where the Airtac SAI50 Standard Cylinder SAI50X800S Is Used
Extended Transfer Lines
Provides the 800 mm reach needed to index large product between robotic processing stations on extended conveyor systems.
High-Bay Push-Out
Delivers 982 N of push force to eject heavy totes from storage tiers, utilizing the full stroke to clear structural obstructions.
Long-Stroke Forming
Actuates large press dies or forming tools over a wide working area, taking advantage of the dual adjustable cushions to stop heavy masses smoothly.
Is the Airtac SAI50 Standard Cylinder SAI50X800S the Right Cylinder?
Selecting this 50 mm bore over the smaller 40 mm variant doubles the thrust, jumping from 528 N to 825 N of pull force at 0.5 MPa, which is critical if you are moving heavier pallets. Conversely, if your application exceeds 1374 N of push force at 0.7 MPa, stepping up to the 63 mm bore is advisable. The G1/4 port and M16x1.5 rod thread are standard for this bore size.
Because the 800 mm stroke pushes the boundary of the standard range, the extended rod is highly susceptible to bending under side loads. To prevent premature rod-bearing failure, mount this cylinder using a trunnion or clevis accessory to allow self-alignment, or pair it with an external guided rail system. Note that the adjustable air cushions at both ends only decelerate the piston near stroke limits; they do not hold a load. If pressure is lost, the piston will drift. For fail-safe holding, use the SAIL variant with an air-released lock or an external pilot-operated check valve.
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 SAI50X800S FAQ
At a standard 0.5 MPa operating pressure, this 50 mm bore cylinder outputs 982 N of push force and 825 N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 1374 N.
Yes. The SAI50X800-S is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions and pin spacing are fully interchangeable with other ISO 15552 cylinders. You can drop it into existing fixtures designed for standard ISO 15552 50x800 units without modifying the mounting plate.
