This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X160CA, 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 SI100X160CA
The AirTAC Airtac SI100 Standard Cylinder SI100X160CA 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 SAI100X160CA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X160CA
The AirTAC SI100X160CA is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 160mm stroke. It delivers 3927N push force at 0.5MPa via a G1/2 port. The direct replacement is the SAI100X160CA, sharing the exact CA clevis mounting, M20x1.5 rod thread, and output force.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this non-S SKU lacks a magnet and cannot take a sensor; the SAI family also adds SAIL, SAIF, and BSAI lock variants.

Where the Airtac SI100 Standard Cylinder SI100X160CA Is Used
Heavy-Duty Pressing
Drives large stamping or forming fixtures requiring substantial thrust, utilizing the 3927N push force available at just 0.5MPa operating pressure.
Bulk Material Diversion
Actuates heavy routing gates on high-capacity conveyor lines, relying on the robust CA clevis mount to withstand pivot stresses.
Replacing the Airtac SI100 Standard Cylinder SI100X160CA with the SAI100X160CA
To replace the SI100X160CA, order the SAI100X160CA. Verify the ISO 15552 CA clevis mounting, 160mm stroke, G1/2 port, and M20x1.5 thread. Because this specific SKU lacks the -S magnet, it cannot accept CS1-B/DS1-B sensors; order a magnet-equipped SAI if position detection is needed. Sizing both ways: the 100mm bore yields 3927N push at 0.5MPa (801kgf max at 1.0MPa), while the neighboring 80mm bore offers 2513N. For loads needing static holding on air loss, note that the air cushion only decelerates at stroke end; add an external pilot check valve or use the SAIL/BSAI lock variant. At 160mm stroke, side-load risks are low, but ensure rod alignment to prevent premature seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X160CA
- ✓ 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 SI100X160CA FAQ
Yes, the SI100X160CA is discontinued. The direct replacement is the AirTAC SAI100X160CA. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 160mm stroke, CA clevis mount, G1/2 port, and output force.
This double-acting cylinder uses a G1/2 air port. The thrust ratings are: 3927N push and 3681N pull at 0.5MPa; 5497N push at 0.7MPa; 7068N push at 0.9MPa; and a theoretical maximum of 801kgf at 1.0MPa.
