This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID160X450S, 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 SID Series Double-Rod Cylinder SID160X450S
The AirTAC Airtac SID Series Double-Rod Cylinder SID160X450S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 450mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID160X450S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID160X450S
The AirTAC SID160X450S is a double-acting double-rod ISO 15552 cylinder where a rod exits both ends, yielding equal push and pull force of 9425 N at 0.5 MPa. This discontinued model drops directly into the SAID160X450S, retaining the 160 mm bore, 450 mm stroke, G3/4 port, and M36x2 rod thread. The SAI replacement upgrades the piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life.
With a 40 mm rod and 50 mm adjustable cushions at each end, speed ranges 30-500 mm/s. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. Note that air cushions only decelerate; use an external rod lock or SAIL/BSAI variant to hold loads on air loss.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAID160X450S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SID Series Double-Rod Cylinder SID160X450S Is Used
Equal-Force Transfer
Drives a conveyor diverter with identical push and pull thrust, using the back rod end to mount a sensor cam for precise positioning.
Anti-Rotation Tooling
Powers a dual-tool machining station where the second rod prevents mechanical rotation, maintaining strict alignment during heavy clamping.
Replacing the Airtac SID Series Double-Rod Cylinder SID160X450S with the SAID160X450S
To replace the discontinued SID160X450S, install the direct replacement SAID160X450S, which matches the ISO 15552 mounting interface, bore, stroke, and force. Size both ways by verifying the 9425 N @0.5 MPa requirement; if lower force is acceptable, step down to the 125 mm bore, or step up to 200 mm for 15080 N. A double rod is right when you need equal both-ways force, anti-rotation stability, or a back rod to carry a sensor cam. Reuse FA, LB, or TC mounts. The -S magnet enables position sensing. For the 450 mm stroke, add external guides to prevent rod bending under side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID160X450S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SID Series Double-Rod Cylinder SID160X450S FAQ
Yes, the SID160X450S is discontinued. The direct replacement is the SAID160X450S, offering the same ISO 15552 interface, 160 mm bore, 450 mm stroke, G3/4 port, and equal both-ways force, but with an upgraded piston seal.
As a double-rod cylinder, 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, the rod thread is M36x2, and it features 50 mm adjustable cushions at each end.
