About the Airtac SAI50 Standard Cylinder SAI50X800
The AirTAC SAI50X800 is a double-acting ISO 15552 profile cylinder built for long-stroke automation. It delivers a practical push force of 982 N at 0.5 MPa and a pull force of 825 N, making it suitable for moving loads over its 800 mm travel distance. The extruded aluminum barrel omits tie-rods for a clean exterior while maintaining strict dimensional interchangeability with other ISO 15552 actuators.
This configuration uses a standard carbon steel piston rod and PT tapered port threads. Because it lacks a magnet, external position sensing relies on standalone switches rather than the integrated sensor grooves. For environments exceeding standard operating temperatures, the seal options can be upgraded from standard TPU to Viton (H) or NBR (N) to match specific fluid and thermal demands.

Where the Airtac SAI50 Standard Cylinder SAI50X800 Is Used
Long-Stroke Material Transfer
Pushes workpieces or pallets across an 800 mm gap on a production line using 982 N of thrust at 0.5 MPa.
High-Bay Ejection
Actuates a long ejection arm to push cartons from a roller conveyor into a high-bay storage aisle.
Large Door Actuation
Opens and closes heavy machine safety doors or guarding panels over a wide 800 mm span.
Is the Airtac SAI50 Standard Cylinder SAI50X800 the Right Cylinder?
Selecting this 800 mm stroke model requires careful attention to side-load management. At this extended length, an unsupported piston rod is highly susceptible to bending under lateral forces. Implementing an external guide rail or switching to a guided cylinder design will protect the rod bearing and prevent premature wear. If your application requires less travel, stepping down to a bore 40 cylinder provides 628 N of push force at 0.5 MPa, which may suffice for lighter payloads.
To achieve a direct replacement per ISO 15552 standards, match the 50 mm bore, 800 mm stroke, PT G1/4 port, and the appropriate mounting accessory from the FA, LB, or TC series. Note that a standard SAI cylinder relies on air pressure to maintain its position; if pneumatic supply is lost, the load will drift. For dead-end holding without live pressure, specify the SAIL variant with an air-released lock or the BSAI clamp-lock cylinder.
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 SAI50X800 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 SAI50X800 is a profile-type cylinder dimensionally interchangeable per ISO 15552. Ensure you match the 50 mm bore, 800 mm stroke, G1/4 port, and mounting accessories for a seamless direct installation.
