This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID160X220, 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 SID Series Double-Rod Cylinder SID160X220 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 SAID160X220, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SID160X220 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, making push and pull force equal at 9425 N (@0.5 MPa). This legacy model is discontinued; the direct replacement is the SAID160X220, matching the 160mm bore, 220mm stroke, G3/4 port, and ISO 15552 mounting interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This non-magnetic SKU cannot accept switches, and the air cushion only decelerates; use an external rod lock for load holding.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAID160X220 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
| Pressure | Push force | Pull force |

| Max (@1.0 MPa) | 2050 kgf | |
The SAID160X220 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| -S | Optional built-in magnet for sensor position sensing. |
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).
Applies 9425 N of identical force on both advance and retract strokes for precision metalforming tasks.
The extended back rod simultaneously drives a secondary gripper, moving parts on an assembly line.
To replace the discontinued SID160X220, install the direct replacement SAID160X220, reusing the existing ISO 15552 mounting (Basic, FA, LB, TC). A double-rod design is right when you need equal force both ways, anti-rotation stability, or a back rod to drive a second tool. Size both ways by checking neighbor bores (125mm or 200mm) against the 9425 N @0.5 MPa equal force. This SKU lacks the -S magnet and cannot take sensors. For stroke lengths of 300mm or longer, verify the side-load limits to prevent guide wear.
Replacement checklist
Yes, the SID160X220 is discontinued. The direct replacement is the SAID160X220, which shares the same ISO 15552 interface, 160mm bore, 220mm stroke, G3/4 port, and equal-both-ways force.
Force is equal both ways: 9425 N @0.5 MPa, 13194 N @0.7 MPa, and 16964 N @0.9 MPa. The air port is G3/4, speed is 30-500 mm/s, and it uses a 40mm rod with M36x2 threading.
Send us the quantity and destination. We confirm price, stock and lead time on the SAID160X220 replacement — usually within 7-8 hours.
