This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID32X450, 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 SID32X450
The AirTAC Airtac SID Series Double-Rod Cylinder SID32X450 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 SAID32X450, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID32X450
The AirTAC SID32X450 is a double-acting, double-rod ISO 15552 cylinder with a 32 mm bore and 450 mm stroke. A rod exits both ends on one piston, meaning both faces use the rod-side area and push/pull force is equal both ways (345 N @0.5 MPa). This discontinued model drops directly into the same mounting interface as the SAID32X450, which uses an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life. The fixed G1/8 port and M10x1.25 rod thread remain identical.
Because the second rod can carry a sensor cam or drive two tools simultaneously while resisting rotation, it offers distinct mechanical advantages. This non-magnet SKU cannot take a switch. Note that air cushions only decelerate; for load holding on air loss, use an external rod lock or SAIL/BSAI variant.

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 SID32X450 Is Used
Dual-Tool Synchronous Drive
Drives two independent workpieces simultaneously from opposite ends of the machine, keeping cycle times aligned without adding a second cylinder.
Anti-Rotation Vertical Lift
Lifts small ~18 kg fixtures vertically with equal both-ways force, using the twin rods to prevent rotational twist during travel.
External Cam Positioning
Uses the extended back rod as a mechanical cam to trip external limit switches, ideal since this non-magnet model cannot carry piston sensors.
Replacing the Airtac SID Series Double-Rod Cylinder SID32X450 with the SAID32X450
To replace the discontinued SID32X450, specify the SAID32X450; it preserves the 450 mm stroke, 32 mm bore, G1/8 port, and ISO 15552 mounting (Basic, FA, LB, TC). When sizing both ways, verify the equal force fits your load, or step up to a 40 mm bore if more Newtons are needed. A double rod is right when you need anti-rotation or must drive two tools. For this 450 mm stroke, use external guides to prevent rod bending under side-load. This SKU lacks the -S magnet, so it cannot support legacy CS1-B/DS1-B sensors.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID32X450
- ✓ 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 SID32X450 FAQ
Yes, the SID32X450 is discontinued. The direct replacement is the SAID32X450. It shares the same ISO 15552 interface, 32 mm bore, 450 mm stroke, G1/8 port, and equal both-ways force, while adding an upgraded piston seal.
Force is equal both ways at 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. The air port is G1/8, rod thread is M10x1.25, and adjustable cushion is 27 mm. It cannot hold a load without live air.
