About the Airtac SAI50 Standard Cylinder SAI50X145S
The AirTAC SAI50X145-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 145 mm stroke provides the exact mid-range extension needed for automated clamping and lifting tasks without excessive retraction length.
This variant includes a built-in magnet for direct compatibility with CMSE and DMSE sensor switches, which seat neatly into the dual grooves on the extruded aluminum barrel. The piston rod uses standard carbon steel for high tensile strength, and fluid routing connects via tapered PT ports.

Where the Airtac SAI50 Standard Cylinder SAI50X145S Is Used
Automated Clamping
Provides reliable 982 N clamping force at 0.5 MPa to secure metal workpieces during machining operations.
Package Diverting
Uses the 145 mm stroke to push cartons off a main conveyor line at high cycling speeds.
Lift Gates
Raises and lowers lightweight access doors or machine guards using continuous double-acting air control.
Is the Airtac SAI50 Standard Cylinder SAI50X145S the Right Cylinder?
Select this 50 mm bore when a 32 mm model's 402 N output is insufficient but a 63 mm cylinder's 1559 N would be physically oversized. The 145 mm stroke offers a compact footprint while maintaining a 30-800 mm/s operating speed range.
Because this is a double-acting cylinder, it relies on continuous air pressure to hold position; if your fixture drops when air is exhausted, integrate the SAIL locking variant or an external pilot check valve. For direct mounting interchangeability, match the 50 mm bore, 145 mm stroke, PT port thread, and your required mounting accessory (such as an FA flange or TC trunnion).
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 SAI50X145S FAQ
At 0.5 MPa operating pressure, 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, it is dimensionally interchangeable per ISO 15552. You can drop it into existing setups by matching the 50 mm bore, 145 mm stroke, and mounting accessories like the LB foot or FA flange.
