This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X65TC, 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 SI100X65TC
The AirTAC Airtac SI100 Standard Cylinder SI100X65TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 65mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X65TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X65TC
The AirTAC SI100X65TC is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 65mm stroke, delivering 3927 N push force at 0.5 MPa via its G1/2 port. AirTAC replaced this EOL unit with the SAI100X65TC, a direct upgrade retaining the exact TC trunnion mount, M20x1.5 rod thread, and 36mm cushions.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Note this no-S SKU lacks a magnet and cannot take a sensor, and the SAI family adds SAIL lock and SAIF valve variants the SI lacked.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI100X65TC carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAI100X65TC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI100 Standard Cylinder SI100X65TC Is Used
Press Fit Assembly
Drives heavy-duty pins and bearings into automotive housings using its 5497 N push force at 0.7 MPa with precise TC trunnion alignment.
Pallet Dispenser
Indexes empty pallets into high-speed packaging lines, utilizing the 200 kg vertical lift capacity and 65mm compact stroke.
Clamp Actuation
Secures large welded steel frames during machining operations, relying on the robust 25mm carbon steel rod for rigidity.
Replacing the Airtac SI100 Standard Cylinder SI100X65TC with the SAI100X65TC
To replace the SI100X65TC, order the SAI100X65TC and confirm the ISO 15552 TC trunnion interface, 100mm bore, 65mm stroke, G1/2 port (PT/G/NPT thread), and M20x1.5 rod. Since this is a no-S SKU, it cannot accept a CS1-B/DS1-B magnetic sensor. Sizing both ways: the 100mm bore yields 3927 N push at 0.5 MPa (safe load 2356 N), while the neighbouring 80mm bore offers 2513 N. A plain cylinder drifts on air loss—the cushion only decelerates—so use a pilot check valve or the SAIL/BSAI lock variant for load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X65TC
- ✓ 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 SI100X65TC FAQ
Yes, the SI100X65TC is discontinued. The direct replacement is the SAI100X65TC. It shares the identical ISO 15552 TC mounting interface, 100mm bore, 65mm stroke, output force, and G1/2 port, fitting existing fixtures perfectly while upgrading the piston seal.
The 100mm bore uses a G1/2 air port. It generates 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 of 801 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
