About the Airtac SAI50 Standard Cylinder SAI50AX105S
The AirTAC SAI50X105-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 105 mm stroke provides a compact extension length perfectly suited for mid-range actuation tasks. Built with an extruded aluminum barrel, this tie-rod-less design ensures smooth operation and easy integration.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. The -S suffix indicates an integrated magnet, allowing seamless operation with CMSE and DMSE sensor switches housed in the dual side grooves. Fluid ports feature PT tapered threading, and the unit supports adjustable air cushions at both ends to dampen impact.

Where the Airtac SAI50 Standard Cylinder SAI50AX105S Is Used
Component Clamping
Provides reliable 982 N holding force at 0.5 MPa for securing mid-sized metal workpieces during machining operations.
Package Diverting
Utilizes the 105 mm stroke to actuate routing gates and pusher arms on automated packaging lines.
Material Ejection
Delivers rapid 30-800 mm/s cycling to eject molded parts or sorted materials from production machinery.
Is the Airtac SAI50 Standard Cylinder SAI50AX105S the Right Cylinder?
Selecting this 50 mm bore over the smaller 40 mm version upgrades your thrust from 628 N to 982 N at 0.5 MPa, while stepping up to the 63 mm bore yields 1559 N. The 105 mm stroke offers a balanced footprint for standard machine spacing. Because this is a double-acting cylinder, it relies entirely on continuous air pressure to move and maintain its load; it will drift if pressure is lost.
As a true ISO 15552 profile cylinder, it serves as a direct replacement for any standard ISO 15552 unit with matching 50 mm bore, 105 mm stroke, G1/4 port, and mounting accessories like FA flanges or TC trunnions. The integrated magnet (-S) ensures out-of-the-box compatibility with standard reed switches.
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 SAI50AX105S FAQ
