About the Airtac SAI100 Standard Air Cylinder SAI100AX50
The AirTAC SAI100X50 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty handling. It generates 3927 N of push force at 0.5 MPa, making it well-suited for short-stroke clamping and high-thrust pressing tasks.
This configuration features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance. It uses PT tapered port threads and lacks a standard magnet, while the extruded aluminum barrel includes dual sensor grooves should you later require position detection.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX50 Is Used
Heavy-Duty Pressing
Provides 3927 N of thrust at 0.5 MPa for seating bearings and stamping components in automated machinery.
Pallet Stopping
Acts as a robust stopper block for heavy pallets on assembly lines, utilizing the short 50mm stroke for rapid deployment.
Industrial Clamping
Secures large metal or composite workpieces during machining, leveraging the SUS420J2 stainless steel rod for durability.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX50 the Right Cylinder?
Select this 100mm bore when a 80mm cylinder lacks thrust; stepping up from an 80mm bore increases your 0.5 MPa push force from 2513 N to 3927 N. The 50mm stroke provides rapid, compact actuation without requiring extensive rod-bearing support.
For drop-in compatibility, match the 100mm bore, 50mm stroke, G1/2 port, and your preferred mounting accessory like an FA flange or TC trunnion. Because this is a standard double-acting cylinder, it will not hold a load if air pressure drops; use an external rod lock or the BSAI clamp-lock variant for fail-safe holding.
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 SAI100AX50 FAQ
At 0.5 MPa operating pressure, the SAI100X50 delivers 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 is dimensionally interchangeable per ISO 15552. You can use it as a drop-in replacement for other ISO 15552 profile cylinders with a 100mm bore and 50mm stroke, matching the G1/2 port and mounting dimensions.
