This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID32X25, 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 SID32X25
The AirTAC Airtac SID Series Double-Rod Cylinder SID32X25 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 25mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID32X25, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID32X25
The AirTAC SID32X25 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston. Both faces use the rod-side area, so push and pull force are equal at 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. This SKU has no -S magnet and cannot take a sensor. It features a 12 mm rod, M10x1.25 thread, G1/8 port, and 27 mm cushions. This discontinued model is replaced by the SAID32X25.
The SAID32X25 is a direct upgrade retaining the exact ISO 15552 interface, bore, stroke, and G1/8 port. The SAI family uses an upgraded two Y-shaped one-way piston seal for low start-up pressure and adds SAIL and BSAI lock variants. A plain cylinder drifts on air loss; cushions only decelerate, so use an external rod lock for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAID32X25 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAID32X25 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 SID32X25 Is Used
Gripper Cam Actuation
Drives a mechanical gripper where the extended back rod simultaneously pushes a cam, utilising the equal both ways force for compact tooling.
Transfer Pusher
Moves lightweight parts along a belt; the double-rod design prevents piston rotation during rapid 30-800 mm/s cycles without needing a separate guide.
Dual-Tool Drive
Powers two separate operations from one piston, with a rod exiting each end to carry independent tooling heads at identical speeds.
Replacing the Airtac SID Series Double-Rod Cylinder SID32X25 with the SAID32X25
Replace the discontinued SID32X25 directly with the SAID32X25, reusing your existing FA, LB, or TC mounts. Size both ways by checking neighbouring bores if 345 N @0.5 MPa is insufficient, ensuring the equal both ways force fits the application. A double rod is right when you need anti-rotation or a back rod to drive a second tool. This SKU lacks a -S magnet, so it cannot support sensing. For stroke >=300 mm, verify side-load limits.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID32X25
- ✓ 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 SID32X25 FAQ
Yes, the SID32X25 is discontinued. The direct replacement is the SAID32X25, which shares the same ISO 15552 interface, 32 mm bore, 25 mm stroke, G1/8 port, and mounting options.
Force is equal both ways: 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. Speed is 30-800 mm/s. It operates at 0.15-1.0 MPa with a G1/8 port.
