This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X200FTC, 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.

The AirTAC Airtac SI160 Standard Cylinder SI160X200FTC 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 SAI160X200FTC, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI160X200FTC is a discontinued double-acting ISO 15552 profile cylinder with an extruded aluminum barrel, delivering a push force of 10053 N at 0.5 MPa. It features a 160 mm bore, 200 mm stroke, G3/4 port, and FTC trunnion mounting. AirTAC replaced this legacy unit with the SAI160X200FTC, a direct replacement retaining the exact ISO 15552 mounting interface, bore, stroke, output force, and port size.
The SAI upgrade introduces an advanced piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note that this specific SKU lacks a magnet (-S) and cannot accept position sensors. Furthermore, the SAI family adds variants the SI line lacked, such as the SAIL air-released lock and BSAI clamp-lock for secure load holding.

The SAI160X200FTC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SI-family variants: SID (double rod), SIJ (adjustable stroke) — each maps to its SAI equivalent (SID→SAID, SIJ→SAIJ). Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B).
Drives heavy tooling in automated stamping lines, utilizing the 14074 N push force at 0.7 MPa to form thick metal components reliably.
Ejects large molded parts from heavy industrial injection machinery, relying on the 50 mm adjustable air cushions to absorb high end-of-stroke kinetic energy.
To replace the discontinued SI160X200FTC, order the SAI160X200FTC. Confirm the ISO 15552 FTC trunnion interface, 160 mm bore, 200 mm stroke, and G3/4 port. Because this SKU lacks the -S magnet suffix, it cannot support legacy CS1-B/DS1-B sensors; order a magnet-equipped version if position detection is required. When sizing, neighboring bores offer different forces: the 125 mm bore provides 6136 N push at 0.5 MPa, while the 200 mm bore yields 15708 N. A plain cylinder drifts without live air and the cushion only decelerates near stroke end; for load holding on air loss, specify an external pilot check valve, rod lock, or the SAIL/BSAI lock variants. The 40 mm carbon steel rod handles high thrust, and seal options include Viton H for high-temperature duties.
Replacement checklist
Yes, the AirTAC SI160X200FTC is discontinued. The direct replacement is the SAI160X200FTC. It is dimensionally interchangeable per ISO 15552, matching the 160 mm bore, 200 mm stroke, G3/4 port, and FTC trunnion mount for a seamless fixture swap.
This double-acting cylinder uses a G3/4 air port. It generates 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 force of 2050 kgf at 1.0 MPa.
