About the Airtac SAI100 Standard Air Cylinder SAI100AX50S
The AirTAC SAI100X50-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty handling. It provides a robust push force of 3927 N at 0.5 MPa, making it well-suited for short, high-impact clamping and lifting tasks. The 50 mm stroke ensures rapid actuation cycles without consuming excessive machine space.
This configuration includes an integrated magnet for use with CMSE and DMSE sensor switches, which seat neatly into the dual grooves machined into the extruded aluminum barrel. The piston rod is constructed from SUS420J2 stainless steel (material code A) for enhanced corrosion resistance, and air flows through a PT-tapered G1/2 port.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX50S Is Used
Heavy-Duty Clamping
Generates 3927 N of push force at 0.5 MPa to secure thick steel plates during welding or machining operations.
Stamping Press Feed
Uses its 50 mm stroke for rapid, short-distance material indexing into heavy stamping presses.
Pallet Lift Stops
Acts as a high-force mechanical stop to halt loaded pallets on conveyor lines without bouncing.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX50S the Right Cylinder?
Select this 100 mm bore when a 63 mm cylinder falls short—the SAI63 offers 1559 N at 0.5 MPa, whereas this model outputs 3927 N. If your application requires less force, stepping down to an 80 mm bore yields 2513 N. Because the 50 mm stroke is short, side-load stress on the rod bearing is minimal, allowing direct mounting without external guides.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard 100 mm bore, 50 mm stroke unit with a G1/2 port and standard mounting accessories like FA flanges or TC trunnions. Note that the adjustable air cushions decelerate the piston at end-of-stroke but do not lock the rod; if you need failsafe holding, consider the SAIL or BSAI variants.
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 SAI100 Standard Air Cylinder SAI100AX50S FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
Yes. The SAI100X50-S is dimensionally interchangeable per ISO 15552. You can drop it into existing 100 mm bore setups using standard mounting accessories and G1/2 ports.
