About the Airtac SAI50 Standard Cylinder SAI50AX115S
The AirTAC SAI50X115-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 115mm stroke. It provides 982N of push thrust at 0.5 MPa and 1374N at 0.7 MPa, making it well-suited for medium-duty handling tasks. This specific configuration includes a SUS420J2 stainless steel piston rod (option A) for enhanced corrosion resistance in humid or mildly chemical environments.
As an ISO 15552 standardized cylinder, it offers a direct dimensional replacement for other cylinders built to the same standard. The integrated magnet (-S) allows direct mounting of CMSE or DMSE reed switches along the extruded aluminum barrel's dual sensor grooves, simplifying position verification.

Where the Airtac SAI50 Standard Cylinder SAI50AX115S Is Used
Component Clamping
Ideal for holding machined parts in place during milling or drilling operations, utilizing the 982N push force at 0.5 MPa to resist cutting forces.
Package Diverting
The 115mm stroke provides just enough extension to push products off a conveyor belt into sorting lanes without taking up excessive machine footprint.
Gate Control
Operates small pneumatic gates or machine guards, where the SUS420J2 stainless steel rod offers reliable service in factory environments exposed to washdowns.
Is the Airtac SAI50 Standard Cylinder SAI50AX115S the Right Cylinder?
Selecting this 50mm bore over the smaller 40mm variant yields a significant force jump from 628N to 982N at 0.5 MPa, whereas stepping up to the 63mm bore provides 1559N for heavier loads. The 115mm stroke is a custom intermediate length that provides an exact extension distance without needing mechanical stops.
Because this is a standard double-acting cylinder, it relies on continuous air pressure to hold the rod in place; if air is exhausted or pressure drops, the piston will drift. For applications requiring true fail-safe load holding, consider the SAIL variant with an air-released lock or the BSAI clamp-lock cylinder. To ensure ISO 15552 interchangeability, match the 50mm bore, 115mm stroke, PT G1/4 port, and appropriate mounting accessories like FA flanges or TC trunnions.
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 SAI50AX115S FAQ
At 0.5 MPa, this 50mm bore cylinder provides 982N of push force and 825N of pull force. If operating pressure is increased to 0.7 MPa, the push force rises to 1374N.
Yes, the SAI50X115-S is a profile cylinder built to ISO 15552 dimensions, making it dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke. Just ensure your setup matches the G1/4 port size.
