About the Airtac SAI50 Standard Cylinder SAI50X55
The AirTAC SAI50X55 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 55mm stroke. It delivers a push force of 982 N at 0.5 MPa, making it well-suited for medium-duty handling tasks that require a compact yet powerful actuator.
This tie-rod-less extruded aluminum barrel includes sensor grooves on both sides for CMSE or DMSE switches, though adding a magnet requires the -S option. The standard configuration uses a carbon steel piston rod and PT tapered port threads, ensuring robust performance in general industrial environments.

Where the Airtac SAI50 Standard Cylinder SAI50X55 Is Used
Automated Clamping
Provides reliable 982 N clamping force at 0.5 MPa for securing mid-sized workpieces during machining or assembly processes.
Package Diverting
The 55mm stroke offers rapid and precise movement for sorting or diverting packages on conveyor lines.
Material Handling
Ideal for lifting and transferring moderate loads in automated manufacturing cells where consistent actuation is required.
Is the Airtac SAI50 Standard Cylinder SAI50X55 the Right Cylinder?
Step down to a 40mm bore for lighter loads (628 N at 0.5 MPa) or up to a 63mm bore (1559 N at 0.5 MPa) if your application requires higher thrust. Because this is a double-acting cylinder, it will not hold a load if air pressure is lost; for position holding, consider the SAIL locking variant or an external rod lock. As a true ISO 15552 profile cylinder, it serves as a direct replacement matching standard 50mm bore, 55mm stroke, G1/4 port, and standard mounting accessories without relying on tie-rods.
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 SAI50X55 FAQ
At an operating pressure of 0.5 MPa, the SAI50X55 generates a push force of 982 N and a pull force of 825 N. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X55 is dimensionally interchangeable per ISO 15552. You can drop it in using the existing 50mm bore, 55mm stroke, and G1/4 port interface without altering your mounting setup.
