This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID32X350S, 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 SID32X350S
The AirTAC Airtac SID Series Double-Rod Cylinder SID32X350S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 350mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID32X350S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID32X350S
The AirTAC SID32X350S is a discontinued double-acting double-rod ISO 15552 cylinder where a rod exits both ends on one piston, making push and pull force equal at 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. It features a 32 mm bore, G1/8 air port, M10x1.25 rod thread, and 27 mm adjustable air cushions at each end. The direct replacement is the SAID32X350S, which reuses the same ISO 15552 mounting interface, bore, stroke, and port. The SAI upgrade uses an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life.
Because both faces use the rod-side area, the equal-both-ways force prevents rod-side drift and allows the back rod to carry a sensor cam. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches. A plain cylinder does not hold loads on air loss; the cushion only decelerates near stroke end, so use an external rod lock or SAIL/BSAI variant for held loads.

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 SID32X350S Is Used
Dual-Tool Machining Station
Drives two opposing tools simultaneously using both rod ends, leveraging the equal push and pull force to maintain balanced machining pressure.
Anti-Rotation Transfer Gate
Uses the double-rod structure to prevent rod rotation during lateral package diversion on a conveyor line, ensuring precise gate alignment.
Symmetrical Clamping Fixture
Clamps thin workpieces from both sides evenly; the equal both-ways force prevents workpiece deformation without requiring external mechanical stops.
Replacing the Airtac SID Series Double-Rod Cylinder SID32X350S with the SAID32X350S
Replace the discontinued SID32X350S directly with the SAID32X350S, matching the 32 mm bore, 350 mm stroke, G1/8 port, and ISO 15552 mounting interface (Basic, FA, LB, TC). Select a double-rod cylinder when equal both-ways force is required to prevent rod-side drift or when the back rod must drive a second tool. If sizing up, verify the equal both-ways force against neighbouring bores. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. For the 350 mm stroke, add external guides to prevent rod bending under side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID32X350S
- ✓ 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 SID32X350S FAQ
Yes, the SID32X350S is discontinued. The direct replacement is the SAID32X350S, offering the same 32 mm bore, 350 mm stroke, G1/8 port, and ISO 15552 mounting interface. The SAI family also adds an upgraded piston seal and SAIL/BSAI lock variants.
As 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. Operating pressure is 0.15-1.0 MPa, speed is 30-800 mm/s, and it features 27 mm adjustable air cushions at each end.
