This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X60SFA, 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 SI100X60SFA
The AirTAC Airtac SI100 Standard Cylinder SI100X60SFA 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 SAI100X60SFA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X60SFA
The AirTAC SI100X60SFA is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm bore and 60 mm stroke. It delivers a push force of 3927 N at 0.5 MPa via a G1/2 port. The direct replacement is the SAI100X60SFA, matching the bore, stroke, force, and FA flange mounting interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. It also adds SAIL, SAIF, and BSAI lock variants. This -S model supports CS1-B/DS1-B sensors.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac SI100 Standard Cylinder SI100X60SFA Is Used
Heavy-Duty Pressing
Applies 3927 N of thrust at 0.5 MPa for seating bearings and forming components securely in automated machining lines.
Pallet Diversion
Uses the FA flange mount to securely push heavy pallets onto secondary conveyor tracks with reliable 100 mm bore force.
Replacing the Airtac SI100 Standard Cylinder SI100X60SFA with the SAI100X60SFA
To replace the SI100X60SFA, order the SAI100X60SFA. Confirm the ISO 15552 interface, 100 mm bore, 60 mm stroke, G1/2 port, and FA flange. The -S magnet enables CS1-B/DS1-B sensors, while the SAI uses current AirTAC switches. For sizing, a neighboring 80 mm bore yields 2513 N push at 0.5 MPa, whereas the 125 mm bore yields 6136 N. Note that a plain cylinder drifts on air loss; the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. Rod material options include carbon steel, SUS420J2, and SUS304.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X60SFA
- ✓ 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 SI100X60SFA FAQ
Yes, the SI100X60SFA is discontinued. The direct replacement is the SAI100X60SFA. It is dimensionally interchangeable per ISO 15552, retaining the same 100 mm bore, 60 mm stroke, force, G1/2 port, and FA flange mounting interface.
This double-acting cylinder uses a G1/2 port. It delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. At 0.7 MPa the push force is 5497 N, and at 0.9 MPa it is 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa.
