This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID32X75S, 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 SID32X75S
The AirTAC Airtac SID Series Double-Rod Cylinder SID32X75S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 75mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID32X75S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID32X75S
The AirTAC SID32X75S is a discontinued double-acting double-rod ISO 15552 cylinder where a rod exits both ends on one piston, ensuring push and pull force are equal at 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. The direct replacement is the SAID32X75S, matching the 32mm bore, 75mm stroke, G1/8 port, and ISO 15552 mounting interface. The SAI upgrade uses an upgraded two Y-shaped one-way piston seal for low start-up pressure and long life.
This 32mm bore features a 12mm piston rod, M10x1.25 rod-end thread, 27mm adjustable air cushions, and 30-800 mm/s speed. 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 | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAID32X75S 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 SID32X75S Is Used
Synchronized Tool Driving
Drives two separate tooling operations simultaneously from a single 32mm bore piston, utilizing the equal both ways force for consistent machining pressure.
Anti-Rotation Indexing
The dual-rod geometry prevents mechanical rotation during traverse, maintaining strict alignment for precision indexing and clamping tasks.
External Cam Sensing
Uses the rear extending rod to carry a sensor cam, allowing external position tracking without interfering with the primary 75mm stroke work area.
Replacing the Airtac SID Series Double-Rod Cylinder SID32X75S with the SAID32X75S
To replace the discontinued SID32X75S, install the direct replacement SAID32X75S which preserves the G1/8 port, 75mm stroke, and ISO 15552 mounting interface. Size both ways by confirming the equal push/pull force of 483 N @0.7 MPa is sufficient, or step up to a 40mm bore neighbour for higher force. A double rod is right when you need anti-rotation stability or need to drive two tools from one piston. Reuse FA, LB, or TC mounts directly. The -S magnet enables position sensing. For stroke lengths over 300mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID32X75S
- ✓ 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 SID32X75S FAQ
Yes, the SID32X75S is discontinued. The direct replacement is the SAID32X75S, offering the same ISO 15552 interface, 32mm bore, 75mm stroke, and G1/8 port.
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 fixed air port size for the 32mm bore is G1/8.
