This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X1000S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SI100 Standard Cylinder SI100X1000S
The AirTAC Airtac SI100 Standard Cylinder SI100X1000S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 1000mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X1000S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X1000S
The AirTAC SI100X1000S is a discontinued double-acting ISO 15552 profile cylinder with a 1000 mm stroke, delivering a push force of 3927 N at 0.5 MPa through its G1/2 port. AirTAC replaced this legacy unit with the SAI100X1000S. Because the SAI maintains the exact ISO 15552 mounting interface, bore, stroke, and output force, it serves as a direct replacement for your existing fixtures.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. For load retention, note that a standard cylinder drifts without live air; the cushion only decelerates. For locking needs, the SAI family adds SAIL and BSAI variants the SI lacked.

Where the Airtac SI100 Standard Cylinder SI100X1000S Is Used
Long-Stroke Material Transfer
Drives heavy pallets across 1000 mm transfer lines, utilizing the 3927 N push force to overcome guide friction and move loads smoothly between machining stations.
Large Press Ejection
Pushes finished stamped parts out of large press beds, where the 100 mm bore and 5497 N output at 0.7 MPa ensure positive ejection of heavy metal blanks.
Replacing the Airtac SI100 Standard Cylinder SI100X1000S with the SAI100X1000S
To replace the SI100X1000S, order the SAI100X1000S, confirming the ISO 15552 mounting interface, the 100 mm bore, the 1000 mm stroke, the G1/2 port, and the -S magnet for CS1-B/DS1-B switches. Sizing both ways: a neighbouring 80 mm bore yields 2513 N push at 0.5 MPa, while a 125 mm bore yields 6136 N. At 0.7 MPa this 100 mm bore pushes 5497 N. Because the stroke is 1000 mm, you must support side loads with an external guide to prevent rod bending. A plain cylinder does not hold load without air; use an external rod lock or pilot check valve, or specify the SAIL/BSAI lock variant. Rod material options include carbon steel, SUS420J2 (A), or SUS304 (B).
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X1000S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI100 Standard Cylinder SI100X1000S FAQ
Yes, the SI100X1000S is discontinued. The direct replacement is the AirTAC SAI100X1000S. It features the same ISO 15552 mounting interface, 100 mm bore, 1000 mm stroke, output force, and G1/2 port, fitting directly into existing fixtures without modifications.
This double-acting cylinder uses a G1/2 air port. The thrust ratings are: 3927 N push and 3681 N pull at 0.5 MPa; 5497 N push at 0.7 MPa; 7068 N push at 0.9 MPa; and a theoretical maximum force of 801 kgf at 1.0 MPa.
