This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X770H, 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 SI160X770H
The AirTAC SI160 Standard Cylinder SI160X770H is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 770mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X770H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X770H
The AirTAC SI160X770H is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 770 mm stroke. Featuring a high-temperature Viton H seal (0 to 150 C) and a 40 mm carbon steel rod, it delivers 10053 N push force at 0.5 MPa through a G3/4 port. The direct replacement is the SAI160X770H, matching the interface, force, and mounting exactly.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. Without a magnet (-S), this SKU cannot take a sensor. Note the SAI family adds SAIL lock and BSAI clamp-lock variants absent in the SI line.

Where the Airtac SI160 Standard Cylinder SI160X770H Is Used
Heavy Press Actuation
Drives large press platens up to 18095 N at 0.9 MPa, utilizing the 50 mm adjustable cushion to halt the 770 mm travel smoothly.
High-Temperature Forming
Operates reliably in hot environments up to 150 C using the Viton H seal, moving heavy industrial tooling with 10053 N push force.
Replacing the Airtac SI160 Standard Cylinder SI160X770H with the SAI160X770H
To replace the SI160X770H, order the SAI160X770H. It drops into existing fixtures per the ISO 15552 mounting interface, retaining the 160 mm bore, 770 mm stroke, G3/4 port, and M36x2 rod thread. Because this is a 770 mm stroke, use external guides to prevent rod bending and side-load damage. If sizing down, the 125 mm bore offers 6136 N [email protected]; sizing up to 200 mm provides 15708 N. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for load holding, or specify the SAIL/BSAI lock variant. This no-magnet SKU cannot accept CS1-B/DS1-B sensors.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X770H
- ✓ 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 SI160X770H FAQ
Yes, the SI160X770H is discontinued. The direct replacement is the SAI160X770H. It is dimensionally interchangeable per ISO 15552, matching the 160 mm bore, 770 mm stroke, G3/4 port, and mounting hardware exactly.
The 160 mm bore uses a G3/4 port. It generates 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, 18095 N at 0.9 MPa, and a theoretical max of 2050 kgf at 1.0 MPa. Speed is 30-500 mm/s.
