This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID32X350STC, 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 SID32X350STC
The AirTAC Airtac SID Series Double-Rod Cylinder SID32X350STC 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 SAID32X350STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID32X350STC
The AirTAC SID32X350STC is a discontinued double-acting double-rod ISO 15552 cylinder where a rod exits both ends, ensuring force is equal both ways 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 port, M10x1.25 rod thread, and 27 mm adjustable cushions. The direct replacement is the SAID32X350STC, which reuses the same ISO 15552 mounting interface, TC accessory, stroke, and magnet.
The SAI upgrade introduces an upgraded piston seal using two Y-shaped one-way elements for low start-up pressure and long life. A double-rod design prevents rotation and lets the rear rod carry a sensor cam. Note that air cushions only decelerate; use an external rod lock or SAIL/BSAI variant to hold loads.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAID32X350STC 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 SID32X350STC Is Used
Transfer Pusher
Equal both ways force drives a conveyor diverter arm in both directions without needing a larger bore, using the back rod to mount a sensor cam.
Gripping Actuator
The double-rod anti-rotation property keeps a precision clamping jaw aligned during 350 mm travel, preventing workpiece twist under load.
Dual-Tool Handler
A rod exiting both ends drives two separate pick-and-place tools simultaneously, maximizing cycle efficiency in compact sorting cells.
Replacing the Airtac SID Series Double-Rod Cylinder SID32X350STC with the SAID32X350STC
To replace the discontinued SID32X350STC, install the direct replacement SAID32X350STC, matching the 32 mm bore, 350 mm stroke, G1/8 port, and TC mounting. Force is equal both ways, so size both directions identically; if more force is needed, step up to the 40 mm bore (528 N @0.5 MPa). Choose a double-rod cylinder when you need anti-rotation stability or a back rod to drive a second tool. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches. For this 350 mm stroke, use external guides to prevent rod bending under side loads. A plain cylinder drifts on air loss; for held loads, add an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID32X350STC
- ✓ 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 SID32X350STC FAQ
Yes, the SID32X350STC is discontinued. The direct replacement is the SAID32X350STC, which shares the same ISO 15552 interface, 32 mm bore, 350 mm stroke, G1/8 port, and TC mounting. The SAI family also adds an upgraded piston seal and SAIL/BSAI lock variants.
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 thread is M10x1.25, and speed ranges from 30-800 mm/s.
