About the Airtac SAI100 Standard Air Cylinder SAI100X25
The AirTAC SAI100X25 is a double-acting ISO 15552 profile cylinder engineered for high-force, short-stroke tasks. It provides a robust push force of 3927 N at 0.5 MPa, making it ideal for heavy pressing and clamping operations within a compact 25 mm travel. The extruded aluminum barrel design omits tie-rods, offering a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
This configuration features a standard carbon steel piston rod and PT tapered port threads. Because it lacks the -S magnet option, it operates without integrated position sensing. For applications involving elevated thermal loads, the standard TPU seals can be swapped for Viton (H) or NBR (N) alternatives to match specific environmental demands.

Where the Airtac SAI100 Standard Air Cylinder SAI100X25 Is Used
Heavy Duty Stamping
Generates 5497 N of push force at 0.7 MPa to firmly stamp or mark thick metal components in automated fabrication lines.
Pallet Clamping
Secures heavy loaded pallets in place during robotic stretch-wrapping or banding processes using its substantial 100 mm bore power.
Press Fit Assembly
Delivers the high initial impact force required to seat large bearings or bushings into housings within a precise 25 mm travel.
Is the Airtac SAI100 Standard Air Cylinder SAI100X25 the Right Cylinder?
Select this 100 mm bore model when a 80 mm cylinder (providing 2513 N push force at 0.5 MPa) cannot generate the necessary thrust for your heavy-duty application. The 25 mm stroke is highly effective for brief, powerful movements. Because the stroke is short, side-load stress on the rod bearing is minimal compared to longer units.
This cylinder is a direct drop-in replacement for any ISO 15552 mounting interface. It utilizes a G1/2 port and supports standard mounting accessories like FA flanges or TC trunnions. Remember that the standard double-acting design relies on continuous air pressure to move; if your system loses pressure, the piston will drift. To lock a load securely without live air, 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 SAI100X25 FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. If you increase the operating pressure to 0.7 MPa, the push force rises to 5497 N.
Yes. The SAI100X25 is a true ISO 15552 profile cylinder, meaning its mounting dimensions are standardized for drop-in interchangeability with equivalent ISO 15552 cylinders from other manufacturers.
