About the Airtac SAI100 Standard Air Cylinder SAI100X90
The AirTAC SAI100X90 is a double-acting profile cylinder with a 100mm bore and 90mm stroke, delivering a robust 3927N of push force at 0.5 MPa. It features an extruded aluminum barrel design that fully complies with the ISO 15552 mounting interface, ensuring a seamless drop-in replacement for other ISO 15552 cylinders. This specific 90mm stroke length is highly effective for short-travel clamping, heavy-duty lifting, and high-force ejection tasks.
Equipped with a standard carbon steel piston rod and PT tapered G1/2 port threads, this model provides reliable service in general industrial environments. The barrel incorporates dual sensor grooves, allowing for direct mounting of CMSE or DMSE switches if a magnet is specified later. For applications requiring higher temperature resistance, the standard TPU seals can be swapped for Viton (H) variants.

Where the Airtac SAI100 Standard Air Cylinder SAI100X90 Is Used
Heavy-Duty Pressing
Ideal for applying high downward force to assemble bearings or stamp components securely into housings.
Product Ejection
Provides the robust 3927N push force needed to eject heavy finished parts from molding or machining fixtures.
Pallet Stopping
Acts as a high-strength stopper block on conveyor lines, halting fully loaded pallets before a processing station.
Is the Airtac SAI100 Standard Air Cylinder SAI100X90 the Right Cylinder?
Selecting this 100mm bore makes sense when the 80mm variant (providing 2513N push force at 0.5 MPa) is insufficient for your load, but you want to avoid the larger footprint of a 125mm cylinder. The 90mm stroke offers ample travel for compact, high-force operations without taking up excessive machine space. Because the stroke is under 300mm, side-load stress on the rod bearing is minimal, though external guides are always recommended if handling heavy off-center loads.
This cylinder uses a PT G1/2 port and is dimensionally interchangeable per ISO 15552, matching standard FA/FB flange or TC trunnion mounting accessories. Note that the adjustable air cushions at both ends only serve to decelerate the piston at stroke end; they do not lock or hold a load. If your application requires dead-stop positioning safety without continuous air pressure, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants instead.
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 SAI100X90 FAQ
At an operating pressure of 0.5 MPa, the SAI100X90 generates a push force of 3927N and a pull force of 3681N. If the pressure is increased to 0.7 MPa, the push force reaches 5497N.
Yes, the SAI100X90 is a genuine AirTAC profile cylinder built to the ISO 15552 standard. It is dimensionally interchangeable with other ISO 15552 cylinders, allowing it to serve as a drop-in replacement using standard mounting hardware.
