This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X1700S, 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 SI160X1700S
The AirTAC SI160 Standard Cylinder SI160X1700S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 1700mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X1700S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X1700S
The AirTAC SI160X1700S is a discontinued double-acting ISO 15552 profile cylinder with a 1700 mm stroke and a 160 mm bore. It generates 10053 N of push force at 0.5 MPa using a G3/4 port. Because 1700 mm exceeds the 1500 mm standard maximum, this is a non-standard, made-to-order length. AirTAC replaced this unit with the SAI160X1700S, a direct alternative retaining the exact ISO 15552 mounting interface, bore, stroke, output force, and port size.
The SAI upgrade features a redesigned piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The SAI family also introduces lock and clamp variants (SAIL, BSAI) absent in the legacy line. This -S model includes a piston magnet for CS1-B/DS1-B sensors, though the SAI replacement uses current AirTAC switches.

Where the Airtac SI160 Standard Cylinder SI160X1700S Is Used
Heavy Material Transfer
Drives large fabricated components along 1700 mm travel distances on assembly lines, utilizing the 10053 N push force at 0.5 MPa to shift heavy steel structures.
Long-Stroke Pressing
Applies steady downward clamping pressure for heavy-duty fabrication tasks, taking advantage of the 50 mm adjustable air cushions to decelerate the massive rod assembly.
Pallet Indexing
Moves loaded pallets through machining cells over extended cycles, relying on the 160 mm bore's 9425 N pull force to reposition substantial weights.
Replacing the Airtac SI160 Standard Cylinder SI160X1700S with the SAI160X1700S
To replace the discontinued SI160X1700S, order the SAI160X1700S. Confirm the ISO 15552 mounting interface, the G3/4 port, the M36x2 rod thread, and your specific mounting accessory (such as LB foot or TC trunnion). Because this 1700 mm length is a non-standard stroke exceeding the 1500 mm maximum, expect made-to-order lead times. At 0.5 MPa, this bore delivers 10053 N push and 9425 N pull; if sizing both ways, a neighbouring 200 mm bore offers 15708 N push, while a 125 mm bore provides 6136 N. For this long 1700 mm stroke, you must use external guides to prevent rod bending and excessive side loads. A plain cylinder does not hold load on air loss—the cushion only decelerates—so use the SAIL or BSAI lock variant, an external rod lock, or a pilot check valve for suspended loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X1700S
- ✓ 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 SI160X1700S FAQ
Yes, the SI160X1700S is discontinued. The direct replacement is the SAI160X1700S. It shares the identical ISO 15552 mounting interface, 160 mm bore, 1700 mm stroke, output force, and G3/4 port, fitting directly into existing fixtures without modifications.
This double-acting cylinder uses a G3/4 air port. The thrust ratings are 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 maximum of 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
