This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100AX160S, 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 SI100AX160S
The AirTAC Airtac SI100 Standard Cylinder SI100AX160S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 160mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100AX160S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100AX160S
The AirTAC SI100AX160S is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm bore and 160 mm stroke. It delivers a thrust of 3927 N at 0.5 MPa, featuring a G1/2 air port and an SUS420J2 stainless steel piston rod (-A). The direct replacement is the SAI100AX160S, which shares the same interface, force, and mounting fixtures.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. Note that plain cylinders drift without live air; for load holding, explore the SAIL or BSAI lock variants.

Where the Airtac SI100 Standard Cylinder SI100AX160S Is Used
Heavy-Duty Pressing
Applies up to 5497 N at 0.7 MPa for seating bearings or forming light components in automated machinery.
Pallet Diversion
Drives robust routing gates or stoppers on high-mass material handling lines with a 160 mm stroke.
Replacing the Airtac SI100 Standard Cylinder SI100AX160S with the SAI100AX160S
To replace the SI100AX160S, order the SAI100AX160S and verify the ISO 15552 mounting interface, 160 mm stroke, G1/2 port, and the -S magnet for CS1-B/DS1-B switches. The SAI family also adds SAIF (built-in valve) and BSAI (clamp-lock) options. For sizing, a neighbouring 80 mm bore yields 2513 N push at 0.5 MPa, while the 125 mm bore offers 6136 N. Remember, a plain cylinder does not hold load without air; use an external rod lock or pilot check valve for holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100AX160S
- ✓ 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 SI100AX160S FAQ
Yes, the SI100AX160S is discontinued. The direct replacement is the SAI100AX160S. It is dimensionally interchangeable per ISO 15552, matching the 100 mm bore, 160 mm stroke, force, G1/2 port, and mounting fixtures.
