This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X240, 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 SI160X240
The AirTAC SI160 Standard Cylinder SI160X240 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 240mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X240, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X240
The AirTAC SI160X240 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 240 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160X240, matching the interface, force, and mounting. Note that 240 mm is a nonstandard stroke.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. This SKU lacks a magnet, so it cannot accept CS1-B/DS1-B sensors. For load holding, use the SAIL or BSAI lock variants, as cushions only decelerate.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI160X240 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAI160X240 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 SI160X240 Is Used
Heavy Stamping Press
Drives large heavy-duty stamping dies requiring 10053 N of push force at 0.5 MPa with robust 50 mm cushions.
Large Clamp Fixture
Secures oversized fabricated components during machining using the 9425 N pull force at 0.5 MPa.
Replacing the Airtac SI160 Standard Cylinder SI160X240 with the SAI160X240
To replace the SI160X240, order the SAI160X240. Confirm the ISO 15552 mounting interface, the 240 mm nonstandard stroke, G3/4 port, and M36x2 rod thread. Since this SKU lacks the -S magnet, it cannot support position sensing. For sizing, a 160 mm bore yields 10053 N push at 0.5 MPa; dropping to a 125 mm bore gives 6136 N, while an 80 mm bore provides 2513 N. For loads needing holding on air loss, choose the SAIL air-released lock or BSAI clamp-lock, because standard cushions only decelerate. The speed range is 30-500 mm/s.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X240
- ✓ 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 SI160X240 FAQ
Yes, the SI160X240 is discontinued. The direct replacement is the SAI160X240, which shares the identical ISO 15552 mounting interface, 160 mm bore, 240 mm stroke, G3/4 port, and output force.
This double-acting cylinder uses a G3/4 port. It delivers 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, 18095 N push at 0.9 MPa, and a maximum theoretical force of 2050 kgf at 1.0 MPa.
