About the Airtac SAI50 Standard Cylinder SAI50X180S
The AirTAC SAI50X180-S is a double-acting profile cylinder with a 50mm bore and 180mm stroke. It provides a thrust of 982 N at 0.5 MPa, making it well-suited for medium-duty handling tasks. Built to the ISO 15552 standard, this extruded aluminum barrel offers a direct replacement for other ISO 15552 cylinders without requiring mounting changes.
This specific configuration includes a piston magnet for use with CMSE and DMSE sensor switches, which ride neatly in the integrated grooves on both sides of the barrel. The standard carbon steel piston rod provides robust durability for general industrial automation, while the adjustable air cushions at both ends ensure smooth deceleration at cycle speeds up to 800 mm/s.

Where the Airtac SAI50 Standard Cylinder SAI50X180S Is Used
Package Sorting
Actuates diverters and pushers on packaging lines, using the integrated magnet to trigger position sensors for precise sorting.
Clamp and Release
Provides reliable clamping force for mid-sized workholding fixtures during machining or assembly processes.
Material Handling
Drives lifting and gating mechanisms in automated material handling systems where a 982 N thrust class is required.
Is the Airtac SAI50 Standard Cylinder SAI50X180S the Right Cylinder?
Choose this 50mm bore when an application requires more force than the 40mm variant (628 N at 0.5 MPa) but does not need the heavier 63mm class (1559 N). At 180mm of travel, the stroke is below the 300mm threshold where side-load bending becomes a critical concern, though external guides are still recommended for heavy off-center loads.
For a seamless ISO 15552 replacement, match the 50mm bore, 180mm stroke, PT G1/4 port, and appropriate mounting accessory like an FA flange or LB foot. Because this is a double-acting cylinder, it relies on continuous air pressure to move; it will not hold a load if pressure drops. If your application requires failsafe position holding without live pressure, 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 SAI50X180S FAQ
At a standard operating pressure of 0.5 MPa, this 50mm bore cylinder 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 SAI50X180-S is built to the ISO 15552 profile standard, making it dimensionally interchangeable with other ISO 15552 cylinders. You can swap it directly using the existing mounting interface and G1/4 ports.
