This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X200S, 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 SI160X200S
The AirTAC SI160 Standard Cylinder SI160X200S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 200mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X200S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X200S
The AirTAC SI160X200S is a discontinued double-acting ISO 15552 profile cylinder featuring a 160 mm bore and 200 mm stroke. Delivering 10053 N push force at 0.5 MPa, it utilized a G3/4 port and M36x2 rod thread. AirTAC replaced this legacy unit with the SAI160X200S, a direct upgrade retaining the exact ISO 15552 mounting interface, bore, stroke, output force, and port size.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The SAI family also introduces SAIL and BSAI lock variants absent in the SI line. Your -S suffix indicates a piston magnet for legacy CS1-B/DS1-B sensors; the SAI uses current AirTAC switches.

Where the Airtac SI160 Standard Cylinder SI160X200S Is Used
Heavy Stamping Press
Drives large heavy-duty stamping dies requiring 10053 N push force at 0.5 MPa, utilizing the robust 40 mm piston rod for high impact resistance.
Industrial Clamp Station
Secures large fabricated steel frames during welding operations, demanding the 9425 N pull force and G3/4 air supply for rapid high-pressure clamping.
Replacing the Airtac SI160 Standard Cylinder SI160X200S with the SAI160X200S
To replace the discontinued SI160X200S, order the SAI160X200S. Verify your ISO 15552 mounting fixtures (LB, FA, CA, TC), the G3/4 port, and the -S magnet requirement. If sizing up or down, note the 125 mm bore yields 6136 N push at 0.5 MPa, while the 200 mm bore provides 15708 N. Because this plain cylinder lacks a lock, load drift occurs on air loss; for held loads, specify the SAIL or BSAI lock variant, or use an external pilot check valve. The 200 mm stroke is short, but for any stroke over 300 mm, add external guides to prevent rod bending under side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X200S
- ✓ 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 SI160X200S FAQ
Yes, the SI160X200S is discontinued. The direct replacement is the AirTAC SAI160X200S. It shares the identical ISO 15552 mounting interface, 160 mm bore, 200 mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly while upgrading the piston seal.
The 160 mm bore provides 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, with a 50 mm adjustable air cushion at both ends.
