This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID32X450S, 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 SID32X450S
The AirTAC Airtac SID Series Double-Rod Cylinder SID32X450S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 450mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID32X450S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID32X450S
The AirTAC SID32X450S is a discontinued double-acting double-rod ISO 15552 cylinder where a rod exits both ends, making push and pull force equal at 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. The direct replacement is the SAID32X450S, matching the 32 mm bore, 450 mm stroke, G1/8 port, and ISO 15552 mounting. The SAI upgrade uses a two Y-shaped one-way piston seal for lower start-up pressure and longer life.
With a 12 mm rod and M10x1.25 thread, this unit provides anti-rotation stability and allows a sensor cam on the back rod. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches. Note that air cushions only decelerate; an external rod lock or SAIL/BSAI variant is needed for load holding.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |

Where the Airtac SID Series Double-Rod Cylinder SID32X450S Is Used
Transfer Pusher
Equal push and pull force moves parts down a line and retracts the tooling without needing a larger bore for the return stroke.
Dual-Tool Drive
The rear rod extends simultaneously to operate a secondary mechanism or sensor cam, synchronizing two actions from one piston.
Anti-Rotation Lift
Dual rods prevent the piston from twisting during vertical lifts, ensuring precise alignment for delicate component placement.
Replacing the Airtac SID Series Double-Rod Cylinder SID32X450S with the SAID32X450S
To replace the discontinued SID32X450S, install the SAID32X450S directly into your existing ISO 15552 FA, LB, or TC mounting without bracket changes. Both cylinders deliver equal both-ways force, so if you need more thrust, step up to the 40 mm bore (528 N @0.5 MPa) rather than expecting a larger single-rod push value. A double-rod design is the right choice when you need anti-rotation stability or want to drive two tools simultaneously. Because the stroke is 450 mm, use external guides to prevent rod bending under side loads. The -S magnet enables position sensing, but remember the air cushion only decelerates near stroke end and will not hold a load on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID32X450S
- ✓ 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 SID32X450S FAQ
Yes, the SID32X450S is discontinued. The direct replacement is the SAID32X450S, which shares the same ISO 15552 interface, 32 mm bore, 450 mm stroke, G1/8 port, and mounting dimensions.
Because it is a double-rod cylinder, force is equal both ways: 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. The air port is G1/8, the rod is 12 mm with an M10x1.25 thread, and speed is 30-800 mm/s.
