This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X75SH, 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 SI100X75SH
The AirTAC Airtac SI100 Standard Cylinder SI100X75SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 75mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X75SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X75SH
The AirTAC SI100X75SH is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm bore and 75 mm stroke. It delivers a push force of 3927 N at 0.5 MPa through a G1/2 port. The direct replacement is the SAI100X75SH, which matches the original bore, stroke, force, and ISO 15552 mounting interface for existing fixtures.
The SAI upgrade introduces 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 the SI lacked. The -H seal option raises operating temperature to 0-150 C.

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 SAI100X75SH 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 SI100X75SH Is Used
Heavy-Duty Pressing
Drives robust pressing and stamping operations requiring high thrust, utilizing the 3927 N push force at 0.5 MPa to form or seat heavy components reliably.
Pallet Handling
Actuates large diverters and lifting stops in high-throughput logistics conveyors, where the 100 mm bore provides the necessary muscle to redirect loaded pallets.
Automated Clamping
Secures substantial workpieces in CNC and machining cells, using the 3681 N pull force to hold parts firmly against vibration and cutting loads.
Replacing the Airtac SI100 Standard Cylinder SI100X75SH with the SAI100X75SH
To replace the SI100X75SH, order the SAI100X75SH. Confirm the ISO 15552 mounting interface, the 75 mm stroke, the G1/2 port, and your mounting accessory (LB, FA, TC, etc.). The -S suffix means a magnet is present for CS1-B/DS1-B switches; the SAI replacement uses current AirTAC switches. Sizing both ways: the neighboring 80 mm bore yields 2513 N push at 0.5 MPa, while the 125 mm bore yields 6136 N. Note that a plain cylinder does not hold load without live air; for load holding, use the SAIL or BSAI lock variant, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X75SH
- ✓ 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 SI100X75SH FAQ
Yes, the SI100X75SH is discontinued. The direct replacement is the SAI100X75SH. It is dimensionally interchangeable per ISO 15552, retaining the same 100 mm bore, 75 mm stroke, output force, G1/2 port, and mounting interface.
This 100 mm bore double-acting cylinder features a G1/2 air port and a 25 mm piston rod. 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 maximum force of 801 kgf at 1.0 MPa.
