This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X60FA, 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 SI100X60FA
The AirTAC Airtac SI100 Standard Cylinder SI100X60FA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 60mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X60FA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X60FA
The AirTAC SI100X60FA is a discontinued double-acting ISO 15552 profile cylinder with an FA flange mount. Delivering 3927 N push force at 0.5 MPa through a 100 mm bore, it features a 60 mm stroke, a G1/2 port, and a Ø25 mm rod. The direct replacement is the SAI100X60FA, which preserves the exact ISO 15552 mounting interface, force output, and dimensions.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this non-magnet SKU cannot accept a sensor; legacy CS1-B/DS1-B switches require an -S model. The family also adds SAIL, SAIF, and BSAI lock variants.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI100X60FA 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 SAI100X60FA 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 SI100X60FA Is Used
Heavy Press Clamping
Applies 3927 N of push force at 0.5 MPa to secure heavy metal components during machining or stamping operations.
Stamping & Forming
Uses the 60 mm stroke to deliver rapid, high-impact actuation for short-travel forming and marking tasks.
Pallet Diverting
Drives robust routing gates on high-capacity conveyor lines where the FA flange mount handles lateral stress.
Replacing the Airtac SI100 Standard Cylinder SI100X60FA with the SAI100X60FA
To replace the SI100X60FA, order the SAI100X60FA. Confirm the ISO 15552 FA flange interface, 100 mm bore, 60 mm stroke, G1/2 port (PT/G/NPT thread), and Ø25 rod. Since this SKU lacks the -S magnet, it cannot support position sensing; order the SAI100X60FAS if you need CS1-B/DS1-B or current AirTAC switches. A plain cylinder drifts on air loss because the cushion only decelerates at stroke end; for load holding, use an external pilot check valve or the SAIL/BSAI lock variant. Sizing both ways: a neighbouring 80 mm bore yields 2513 N push at 0.5 MPa, while a 125 mm bore yields 6136 N. Theoretical max force is 801 kgf at 1.0 MPa.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X60FA
- ✓ 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 SI100X60FA FAQ
Yes, the SI100X60FA is discontinued. The direct replacement is the SAI100X60FA. It is dimensionally interchangeable per ISO 15552, retaining the same 100 mm bore, 60 mm stroke, G1/2 port, and FA flange mount.
This double-acting cylinder has a G1/2 port. It delivers 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 max force of 801 kgf at 1.0 MPa.
