This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X190TC, 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 SI160 Standard Cylinder SI160X190TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 190mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X190TC, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI160X190TC is a discontinued double-acting ISO 15552 profile cylinder featuring a 160mm bore and 190mm stroke. It delivers 10053N push force at 0.5MPa via a G3/4 port. AirTAC replaced this legacy unit with the SAI160X190TC, a direct replacement retaining the exact TC trunnion mount, M36x2 rod thread, and 50mm cushions.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and longevity. Note this non-S SKU lacks a magnet and cannot take a sensor. The SAI family also adds SAIL and BSAI lock variants absent in the SI line.

| Max (@1.0 MPa) | 2050 kgf | |
The SAI160X190TC 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 large presses and stamping fixtures requiring up to 14074N push force at 0.7MPa with stable TC trunnion alignment.
Secures industrial injection molds via the ISO 15552 interface, utilizing the 50mm adjustable air cushions to decelerate heavy masses.
To replace the SI160X190TC, order the SAI160X190TC to secure the identical ISO 15552 mounting interface, 160mm bore, 190mm stroke, G3/4 port, and TC trunnion accessory. When sizing, a neighbouring 200mm bore offers more thrust, while dropping to 125mm reduces the footprint but yields only 6136N push at 0.5MPa. Because this plain cylinder cannot hold a load without live air—the cushion only decelerates—use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant for fail-safe holding. As the stroke is under 300mm, side-load rod-bending risks are minimal, but always verify guide alignment.
Replacement checklist
Yes, the SI160X190TC is discontinued. The direct replacement is the SAI160X190TC. It is dimensionally interchangeable per ISO 15552, retaining the same 160mm bore, 190mm stroke, G3/4 port, TC mounting, and output force.
This double-acting cylinder uses a G3/4 air port. It delivers 10053N push and 9425N pull at 0.5MPa, 14074N push at 0.7MPa, 18095N push at 0.9MPa, and a theoretical max of 2050kgf at 1.0MPa. Operating speed is 30-500mm/s.
Send us the quantity and destination. We confirm price, stock and lead time on the SAI160X190TC replacement — usually within 7-8 hours.
