This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X480S, 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 SI160X480S
The AirTAC SI160 Standard Cylinder SI160X480S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 480mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X480S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X480S
The AirTAC SI160X480S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 480 mm stroke. Delivering 10053 N push force at 0.5 MPa via a G3/4 port, it is replaced by the direct replacement SAI160X480S. The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life, while the SAI family adds SAIL, SAIF and BSAI lock variants the SI lacked.
The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B sensors; the SAI replacement uses current AirTAC switches. A Viton H seal option raises the operating temperature to 150 C.

Where the Airtac SI160 Standard Cylinder SI160X480S Is Used
Heavy Pressing
Drives large stamping and forming presses requiring up to 14074 N of thrust at 0.7 MPa.
Clamp Fixtures
Secures large machined components during milling, utilizing the 50 mm adjustable cushions to decelerate.
Replacing the Airtac SI160 Standard Cylinder SI160X480S with the SAI160X480S
To replace the SI160X480S, order the SAI160X480S. It is a direct per the ISO 15552 mounting interface, matching the 160 mm bore, 480 mm stroke, M36x2 rod thread, 50 mm cushions, G3/4 port and all mounting accessories. Because the 480 mm stroke is long, use an external guide to prevent rod bending and side loads. If sizing up or down, check neighboring bores and the 0.5 MPa force ratings. A plain cylinder drifts on air loss; for load holding, use the SAIL or BSAI lock variant, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X480S
- ✓ 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 SI160X480S FAQ
Yes, the SI160X480S is discontinued. The direct replacement is the SAI160X480S. It shares the exact ISO 15552 mounting interface, 160 mm bore, 480 mm stroke, output force, G3/4 port and mounting accessories, fitting existing fixtures perfectly.
At 0.5 MPa it provides 10053 N push and 9425 N pull. 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.
