About the Airtac SAI50 Standard Cylinder SAI50X55S
The AirTAC SAI50X55-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 55 mm stroke provides compact linear movement for mid-range automation tasks.
This variant includes an integrated magnet for position sensing using CMSE or DMSE switches, which seat neatly into the dual extruded sensor grooves on the aluminum barrel. It features a standard carbon steel piston rod and tapered PT port threads.

Where the Airtac SAI50 Standard Cylinder SAI50X55S Is Used
Package Diverting
Provides rapid actuation for diverting medium-weight packages along sorting conveyor lines.
Clamping Fixtures
Secures workpieces during light machining or assembly operations with reliable 982 N force.
Pallet Stops
Acts as a compact pneumatic stop mechanism for pallets entering processing stations.
Is the Airtac SAI50 Standard Cylinder SAI50X55S the Right Cylinder?
If your application requires less force, stepping down to a 40 mm bore yields 628 N at 0.5 MPa; conversely, moving up to a 63 mm bore provides 1559 N. Because this 55 mm stroke is relatively short, side-load stress on the rod bearing is minimal.
Being a true ISO 15552 profile cylinder, it serves as a direct replacement matching the standardized mounting interface, 50 mm bore, 55 mm stroke, PT G1/4 ports, and standard accessories. Note that this standard cylinder relies on air pressure to hold position; it will drift if air is lost, so consider the SAIL variant if pneumatic locking is required.
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.
