This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X220S, 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 SI160X220S
The AirTAC SI160 Standard Cylinder SI160X220S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 220mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X220S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X220S
The AirTAC SI160X220S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 220 mm stroke. Delivering 10053 N push force at 0.5 MPa, it features a G3/4 port and a magnetic piston for CS1-B/DS1-B switches. AirTAC replaced this EOL unit with the SAI160X220S.
The SAI160X220S is a direct replacement retaining the exact ISO 15552 mounting interface, bore, stroke, output force, and port size. It upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. For high heat, choose Viton H seals; for load holding, use the SAIL lock or BSAI clamp-lock variants.

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 SAI160X220S 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 SI160X220S Is Used
Heavy Stamping
Drives large presses and stamping dies requiring 10053 N of push force at 0.5 MPa with stable ISO 15552 mounting.
Pallet Handling
Indexes heavy pallets and materials on conveyors, utilising the 220 mm stroke and 50 mm adjustable cushions.
Replacing the Airtac SI160 Standard Cylinder SI160X220S with the SAI160X220S
To replace the SI160X220S, order the SAI160X220S. It drops directly into existing fixtures via the ISO 15552 mounting interface, matching the 160 mm bore, 220 mm stroke, M36x2 rod thread, and G3/4 port. Confirm your mounting accessory (LB foot, FA flange, TC trunnion) and thread type (PT/G/NPT). The -S magnet enables CS1-B/DS1-B sensors (the SAI uses current AirTAC switches). For sizing, neighbouring bores are 125 mm (6136 N [email protected]) and 200 mm (15708 N). A plain cylinder drifts without live air; the cushion only decelerates. For held loads, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. At 220 mm stroke, side-load is minimal, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X220S
- ✓ 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 SI160X220S FAQ
Yes, the SI160X220S is discontinued. The direct replacement is the AirTAC SAI160X220S. It shares the identical ISO 15552 mounting interface, 160 mm bore, 220 mm stroke, G3/4 port, and output force, fitting existing fixtures perfectly while upgrading the piston seal.
The 160 mm bore features a G3/4 port and M36x2 rod thread. Force output is 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 theoretical max of 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
