This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X175SH, 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 SI100X175SH
The AirTAC Airtac SI100 Standard Cylinder SI100X175SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 175mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X175SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X175SH
The AirTAC SI100X175SH is a discontinued double-acting ISO 15552 profile cylinder featuring a 100mm bore and 175mm stroke. Delivering 3927 N push force at 0.5 MPa, it includes an adjustable 36mm air cushion at both ends and a G1/2 port. The direct replacement is the SAI100X175SH, which matches the exact ISO 15552 mounting interface, bore, stroke, output force, and porting.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. This configuration includes the -S magnet for legacy CS1-B/DS1-B sensors and the -H Viton seal, raising the operating temperature range from -20 to +70 C up 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 SAI100X175SH 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 SI100X175SH Is Used
Heavy Press Clamping
Applies 5497 N of thrust at 0.7 MPa to secure heavy metal housings during machining operations.
Pallet Lift Stations
Raises 200 kg loaded pallets vertically using the 175mm stroke, guided externally to prevent rod bending.
High-Temp Ejection
Utilizes the Viton H seal to reliably eject freshly molded components in environments up to 150 C.
Replacing the Airtac SI100 Standard Cylinder SI100X175SH with the SAI100X175SH
To replace the discontinued SI100X175SH, order the SAI100X175SH direct equivalent, verifying the ISO 15552 mounting interface, G1/2 port, M20x1.5 rod thread, and the -S magnet and -H Viton seal options. Sizing both ways: the neighboring 80mm bore yields 2513 N push at 0.5 MPa, while the 125mm bore yields 6136 N; this 100mm bore provides 5497 N at 0.7 MPa. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants for load holding. The SAIF variant (bores 32-100) integrates a 4M valve if self-actuation is needed.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X175SH
- ✓ 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 SI100X175SH FAQ
Yes, the SI100X175SH is discontinued. The direct replacement is the SAI100X175SH, a current-production ISO 15552 cylinder with the same 100mm bore, 175mm stroke, 5497 N force at 0.7 MPa, G1/2 port, and mounting footprint.
The G1/2 port bore 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 of 801 kgf at 1.0 MPa. It operates at 30-800 mm/s.
