About the Airtac SAI100 Standard Air Cylinder SAI100AX35
The AirTAC SAI100X35 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty tasks requiring short, rapid movements. Delivering a robust 3927 N of push force at 0.5 MPa, this 100 mm bore unit is built around an extruded aluminum barrel without tie-rods. Its 35 mm stroke excels in high-force clamping and holding operations.
This specific configuration utilizes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. Fluid routing connects via PT tapered threads, and the barrel omits the standard magnet, meaning position sensing via CMSE or DMSE switches is not enabled for this build.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX35 Is Used
Heavy-Duty Stamping
Provides the intense 3927 N impact force needed for short-stroke metal forming, riveting, and stamping presses.
Industrial Clamping
Secures large molds or heavy workpieces in machining centers, using its 100 mm bore to generate unwavering holding power.
Pallet Positioning
Acts as a robust stopper or alignment pusher for heavy-loaded pallets on high-throughput conveyor lines.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX35 the Right Cylinder?
Select this 100 mm bore model when your application demands substantial thrust within a compact footprint. If 3927 N at 0.5 MPa exceeds your requirements, stepping down to an 80 mm bore yields 2513 N, optimizing air consumption. Conversely, moving up to a 125 mm bore provides 6136 N for heavier loads.
Because the stroke is only 35 mm, side-load stress on the rod bearing is minimal, negating the need for external guide rails. Remember that standard air cushions only decelerate the piston at end-of-stroke; they do not lock the rod. If the mechanism must hold a load mechanically during a pressure loss, specify the SAIL variant with an air-released lock or the BSAI clamp-lock cylinder.
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 SAI100AX35 FAQ
At an operating pressure of 0.5 MPa, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. If pressure increases to 0.7 MPa, the push force reaches 5497 N.
Yes. The SAI100X35 is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 cylinders. You can drop it into existing mounts designed for standard 100 mm bore ISO cylinders.
