About the Airtac SAI50 Standard Cylinder SAI50X475
The AirTAC SAI50X475 is a double-acting ISO 15552 profile cylinder engineered to deliver a push force of 982 N and a pull force of 825 N at 0.5 MPa. Its 475 mm stroke makes it well-suited for mid-range linear actuation tasks requiring reliable positioning. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies cleaning and sensor placement.
This standard configuration features a robust carbon steel piston rod and PT tapered port threads. Because a magnet is not specified, it operates without integrated position sensing. For high-temperature environments up to 70 C, the standard TPU seals handle typical demands, while Viton (H) alternatives are available for elevated thermal loads.

Where the Airtac SAI50 Standard Cylinder SAI50X475 Is Used
Package Diversion
Pushes medium-weight cartons across a sorting line using its 475 mm stroke and 982 N of thrust at 0.5 MPa.
Clamping Fixture
Secures workpieces during machining operations, utilizing the 825 N pull force to hold components firmly in place.
Pallet Handling
Indexes empty pallets into a wrapping station, where the 50 mm bore provides sufficient force without excessive air consumption.
Is the Airtac SAI50 Standard Cylinder SAI50X475 the Right Cylinder?
Selecting this 50 mm bore over a smaller 40 mm option steps the thrust up significantly from 628 N to 982 N at 0.5 MPa. If your application requires less force, dropping to a 40 mm bore saves space. At a 475 mm stroke, the unsupported rod length increases susceptibility to bending under side loads. To prevent premature rod-bearing wear, implement an external guide rail or choose a fully guided cylinder.
This model serves as a direct dimensional direct replacement for any ISO 15552 cylinder. To match an existing installation, pair the 50 mm bore, 475 mm stroke, and G1/4 PT port with your preferred mounting accessory, such as an FA flange or TC trunnion. Note that because a magnet is omitted (-S not specified), you cannot mount reed or solid-state sensors.
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 SAI50X475 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 increases to 0.7 MPa, the push force rises to 1374 N.
No, the standard SAI50X475 is double-acting and will drift if air pressure is lost. The adjustable air cushion only decelerates the piston at stroke ends. For position holding, consider the SAIL lock variant or an external pilot-operated check valve.
