This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X500CA, 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 SI160X500CA
The AirTAC SI160 Standard Cylinder SI160X500CA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 500mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X500CA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X500CA
The AirTAC SI160X500CA is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 500 mm stroke. Delivering 10053 N push force at 0.5 MPa via a G3/4 port, it is replaced by the SAI160X500CA. This direct successor shares the exact CA mounting, M36x2 thread, and 2050 kgf max output.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. Note this non-magnet SKU cannot take a sensor. If heat is a factor, Viton H seals raise the range to 150 C.

Where the Airtac SI160 Standard Cylinder SI160X500CA Is Used
Heavy Press Operations
Drives large platens requiring 14074 N push at 0.7 MPa to form or stamp heavy industrial materials.
Pallet Lifting Arms
Actuates robust lifting mechanisms where the 512 kg vertical lift capacity handles substantial loaded pallets.
Large Mold Clamping
Secures oversized injection molds, utilizing the 18095 N output at 0.9 MPa to hold components rigidly.
Replacing the Airtac SI160 Standard Cylinder SI160X500CA with the SAI160X500CA
To replace the SI160X500CA, order the SAI160X500CA. It drops into existing fixtures via the ISO 15552 CA clevis interface, matching the 160 mm bore, 500 mm stroke, G3/4 port, and 50 mm cushions. Sizing both ways: a 200 mm bore offers more thrust, while a 125 mm bore provides 6136 N push at 0.5 MPa. Because this 500 mm stroke invites rod bending, use external guides to prevent side loads. This SKU lacks a magnet, so it cannot accept CS1-B/DS1-B sensors. The cushion only decelerates; for load holding on air loss, use an external rod lock or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X500CA
- ✓ 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 SI160X500CA FAQ
Yes, the SI160X500CA is discontinued. The direct replacement is the SAI160X500CA. It shares the identical ISO 15552 CA mounting interface, 160 mm bore, 500 mm stroke, G3/4 port, and output force, fitting existing fixtures perfectly.
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, and 18095 N push at 0.9 MPa. The theoretical max force is 2050 kgf at 1.0 MPa. Speed is 30-500 mm/s.
