This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID32X80S, 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 SID32X80S
The AirTAC Airtac SID Series Double-Rod Cylinder SID32X80S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 80mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID32X80S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID32X80S
The AirTAC SID32X80S is a discontinued 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. The direct replacement is the SAID32X80S, retaining the 32mm bore, 80mm stroke, G1/8 port, and mounting interface. The SAI upgrade uses a two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The dual-rod design prevents rotation and lets the back rod carry a sensor cam. It features a 12mm rod, M10x1.25 thread, 27mm cushions, and 30-800 mm/s speed. The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B switches. A plain cylinder drifts on air loss; cushions only decelerate, so 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 SAID32X80S 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 SID32X80S Is Used
Synchronized Tool Driving
Drives two separate mechanisms from one piston, utilizing both rod ends to actuate opposing tools simultaneously with equal 345 N @0.5 MPa force.
Anti-Rotation Guiding
The dual-rod architecture prevents piston rotation, ideal for precision gripping tasks where angular deflection cannot be tolerated.
Dual-End Sensor Cam
Uses the rear exiting rod to carry a sensor cam, allowing position confirmation via legacy CS1-B/DS1-B switches without exposing front-end tooling.
Replacing the Airtac SID Series Double-Rod Cylinder SID32X80S with the SAID32X80S
To replace the discontinued SID32X80S, specify the SAID32X80S, which is a direct swap for the ISO 15552 mounting interface, bore, stroke, and G1/8 port. Size both ways by checking the equal push/pull force: 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. If more force is needed, step up to the 40mm bore (528 N @0.5 MPa); if less is required, the 32mm is the smallest standard option. Choose a double-rod cylinder when you need anti-rotation stability or want to drive two tools simultaneously. Reuse existing FA, LB, or TC mounts. Keep the -S option for the piston magnet. For strokes >=300mm, verify side-load limits to prevent binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID32X80S
- ✓ 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 SID32X80S FAQ
Yes, the SID32X80S is discontinued. The direct replacement is the SAID32X80S. It shares the identical ISO 15552 mounting interface, 32mm bore, 80mm stroke, G1/8 port, and equal both-ways force, but adds an upgraded two Y-shaped one-way piston seal.
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 is G1/8. It operates at 0.15-1.0 MPa with a 12mm rod and 27mm adjustable cushions at each end.
