About the Airtac SAI50 Standard Cylinder SAI50X450S
The AirTAC SAI50X450-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa and 825 N of pull force. Its 450 mm stroke provides the extended travel needed for material transfer and automated clamping tasks. The extruded aluminum barrel design eliminates traditional tie-rods, offering a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
Configured with a standard carbon steel piston rod and a built-in magnet (-S), this model is ready for CMSE and DMSE reed sensors. The barrel features sensor grooves on both sides for flexible switch mounting. It uses PT tapered port threads (G1/4) and includes adjustable air cushions at both ends to decelerate the piston smoothly at stroke completion.

Where the Airtac SAI50 Standard Cylinder SAI50X450S Is Used
Extended Material Transfer
Pushes products or workpieces across a 450 mm gap between conveyor belts or processing stations using 982 N of thrust.
Automated Edge Clamping
Secures large sheet metal or composite panels in a machining fixture, utilizing the 50 mm bore force and long stroke reach.
Carton Push-off System
Diverts or rejects heavy packaged goods from a high-speed packaging line, relying on the adjustable cushions to stop smoothly.
Is the Airtac SAI50 Standard Cylinder SAI50X450S the Right Cylinder?
This 50 mm bore is an optimal step up from a 40 mm cylinder (which provides 628 N at 0.5 MPa) when your application demands greater thrust without jumping to the larger 63 mm size. At a 450 mm stroke, the extended rod is highly susceptible to bending under side loads. To prevent premature wear on the rod bearing and seal damage, pair this cylinder with an external linear guide or use a fully guided cylinder.
For direct compatibility with other ISO 15552 cylinders, match the 50 mm bore, 450 mm stroke, G1/4 port, and appropriate mounting accessories like FA flange or LB foot brackets. If the machinery loses air pressure, this standard cylinder cannot hold its load; for fail-safe holding, consider the SAIL variant with an air-released lock or an external rod lock.
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 SAI50X450S FAQ
At a standard operating pressure of 0.5 MPa, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X450-S is a profile cylinder built to ISO 15552 dimensional standards, making it interchangeable with other ISO 15552 cylinders of the same bore and stroke. Ensure your mounting interface and G1/4 ports align during installation.
