About the Airtac SAI100 Standard Air Cylinder SAI100BX35
The AirTAC SAI100X35 is a double-acting ISO 15552 profile cylinder engineered to deliver robust linear motion. Operating at 0.5 MPa, it generates 3927 N of push force and 3681 N of pull force, making it well-suited for heavy-duty clamping and holding tasks within its 35 mm stroke. The extruded aluminum barrel omits tie rods for a clean exterior.
This specific configuration features a SUS304 stainless steel piston rod (material code B), providing excellent corrosion resistance for humid or chemically exposed settings. It utilizes PT tapered port threads and lacks a magnet, meaning it is optimized purely for pneumatic actuation rather than direct magnetic sensing.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX35 Is Used
Heavy-Duty Stamping
Provides the high force needed for short-stroke stamping and forming operations in metal fabrication lines.
Pallet Halting
Acts as a robust stopper block for heavy pallets on conveyor lines, absorbing impact with its rigid 100 mm bore construction.
Parts Ejection
Delivers rapid, high-force ejection of molded or machined parts from machinery, leveraging the 35 mm stroke for quick cycling.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX35 the Right Cylinder?
Choose this 100 mm bore when your application requires upward of 3927 N of push force at 0.5 MPa but only a short 35 mm stroke. If your force requirements are lower, stepping down to an 80 mm bore yields 2513 N of push force, saving space and air consumption. Because the stroke is short, side-load stress on the rod bearing is minimal.
As a standard double-acting cylinder, the SAI100X35 relies on live air pressure to maintain its position. If pneumatic supply is lost, the piston will drift. For applications that must hold a load securely during exhaust or pressure loss, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. This model serves as a direct dimensional drop-in replacement for any ISO 15552 profile cylinder with matching 100 mm bore, 35 mm stroke, and G1/2 port specifications.
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 SAI100BX35 FAQ
At a 0.5 MPa operating pressure, the SAI100X35 generates a push force of 3927 N and a pull force of 3681 N. At its maximum rated pressure of 1.0 MPa, the theoretical push force reaches 801 kgf.
Yes, the SAI100X35 is a genuine ISO 15552 profile cylinder. Its mounting interface and dimensions are interchangeable with other ISO 15552 cylinders of the same bore and stroke, provided the G1/2 port and PT thread match your existing plumbing.
