About the Airtac SAI50 Standard Cylinder SAI50X45S
The AirTAC SAI50X45-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 45mm stroke. It generates a push force of 982 N and a pull force of 825 N at 0.5 MPa, making it a robust choice for moderate-duty handling. The extruded aluminum barrel design omits tie rods, providing a clean exterior that drops right into standard ISO 15552 mounting interfaces.
This specific configuration includes a standard carbon steel piston rod and a built-in magnet for proximity sensing. The dual sensor grooves on both sides of the barrel allow for seamless installation of CMSE or DMSE reed switches anywhere along the stroke. For environments requiring higher heat resistance, the seal options can be upgraded from standard TPU to Viton (H) or NBR (N).

Where the Airtac SAI50 Standard Cylinder SAI50X45S Is Used
Material Handling Gates
Provides the 982 N push force needed to actuate heavy diverters and sorting gates on high-speed packaging conveyors.
Clamping Fixtures
Ideal for securely holding workpieces in CNC machining stations where short, 45mm clamping strokes are required.
Pallet Stops
Reliable stopping power for pallets on roller conveyors, utilizing the integrated magnet for precise end-of-stroke confirmation.
Is the Airtac SAI50 Standard Cylinder SAI50X45S the Right Cylinder?
This 50mm bore offers a noticeable strength upgrade over the 40mm version, which provides 628 N of push force at 0.5 MPa. If your application demands even less footprint and 402 N is sufficient, stepping down to a 32mm bore is the logical choice. The 45mm stroke is ideal for short, rapid movements.
Because this is a standard double-acting cylinder, it relies on continuous air pressure to hold position. If power is lost or air is exhausted, the piston will drift. For applications that require true load holding without live pressure, consider the SAIL variant with an air-released lock or the BSAI clamp-lock cylinder. When integrating this model, ensure your setup uses PT tapered port threads and the appropriate ISO 15552 mounting accessories like FA flanges or LB foot brackets.
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 SAI50X45S FAQ
At 0.5 MPa operating pressure, the SAI50X45-S provides a push (extend) force of 982 N and a pull (retract) force of 825 N. At its maximum 1.0 MPa pressure, it can deliver up to 200 kgf of theoretical force.
Yes, the SAI50X45-S is dimensionally interchangeable per ISO 15552. It serves as a direct replacement for other ISO 15552 profile cylinders, matching standard mounting dimensions and G1/4 port locations.
