This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X175SCA, 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 SI160 Standard Cylinder SI160X175SCA
The AirTAC SI160 Standard Cylinder SI160X175SCA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 175mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X175SCA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X175SCA
The AirTAC SI160X175SCA is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 175 mm stroke. It delivers 10053 N push force at 0.5 MPa, features a 40 mm rod, M36x2 thread, and a G3/4 port. The direct replacement is the SAI160X175SCA, matching the bore, stroke, force, port, and CA clevis mounting interface for seamless fixture integration.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. For load holding, note that a standard cylinder drifts without live air; the cushion only decelerates. Use the SAIL or BSAI lock variants if needed. The -S magnet works with CS1-B/DS1-B sensors.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAI160X175SCA produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI160 Standard Cylinder SI160X175SCA Is Used
Heavy Stamping Press
Drives large heavy-duty stamping dies requiring 10053 N push force at 0.5 MPa with robust CA clevis mounting.
Automotive Assembly Jig
Actuates substantial clamping arms on vehicle frames, utilizing the 175 mm stroke to clear large workpieces.
Replacing the Airtac SI160 Standard Cylinder SI160X175SCA with the SAI160X175SCA
To replace the SI160X175SCA, order the SAI160X175SCA. Verify the ISO 15552 CA clevis mount, 175 mm stroke, G3/4 port, and the -S magnet for CS1-B/DS1-B sensors. At 0.5 MPa it yields 10053 N push (9425 N pull); if undersizing, a 125 mm bore provides 6136 N. Because stroke is 175 mm, ensure guide alignment to prevent rod bending. A plain cylinder does not hold load on air loss; for holding, use the SAIL lock variant or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X175SCA
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI160 Standard Cylinder SI160X175SCA FAQ
Yes, the SI160X175SCA is discontinued. The direct replacement is the SAI160X175SCA. It is dimensionally interchangeable per ISO 15552, matching the 160 mm bore, 175 mm stroke, G3/4 port, and CA clevis mount.
At 0.5 MPa it pushes 10053 N and pulls 9425 N. At 0.7 MPa push is 14074 N, and at 0.9 MPa it is 18095 N. The theoretical max is 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
