This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID80X1000STC, 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 SID80X1000STC
The AirTAC Airtac SID Series Double-Rod Cylinder SID80X1000STC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1000mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID80X1000STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID80X1000STC
The AirTAC SID80X1000STC is a discontinued double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, ensuring push and pull force is equal both ways (2268 N at 0.5 MPa). Because both faces use the identical rod-side area, you never get a larger single-rod push value. The direct replacement is the SAID80X1000STC, matching the 80 mm bore, 1000 mm stroke, G3/8 port, and TC mounting interface. The SAI family upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure and long life.
This 80 mm bore features a Ø25 mm piston rod, M20x1.5 rod-end thread, and 36 mm adjustable air cushions at each end. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches. Note that 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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAID80X1000STC 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 SID80X1000STC Is Used
Dual-End Transfer Pusher
Uses the extending back rod to push a part onto a parallel conveyor while the front rod simultaneously retracts a diverter, keeping cycle time strictly synchronized.
Anti-Rotation Gripper Slide
Drives a precision machining gripper where the twin rods prevent torsional twist during heavy clamping, ensuring the jaws remain perfectly aligned under high lateral stress.
Symmetric Pallet Lift Arm
Powers a vertical lifting mechanism in a packaging line where the second rod acts as a mechanical stop or cam, maintaining equal force both up and down for stable pallet handling.
Replacing the Airtac SID Series Double-Rod Cylinder SID80X1000STC with the SAID80X1000STC
To replace the discontinued SID80X1000STC, install the SAID80X1000STC directly into your existing ISO 15552 TC mount. Size both ways by checking the equal force: this 80 mm bore delivers 2268 N at 0.5 MPa, sitting between the 50 mm (1154 N) and 100 mm (5153 N) neighbour bores. A double rod is right when you need anti-rotation stability or want to drive two tools from one piston. The -S magnet enables position sensing, while the G3/8 port is fixed by the bore. Because the stroke is 1000 mm, you must support side-load and rod-bending forces with external guides to prevent binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID80X1000STC
- ✓ 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 SID80X1000STC FAQ
Yes, the SID80X1000STC is discontinued. The direct replacement is the SAID80X1000STC, which shares the identical ISO 15552 interface, 80 mm bore, 1000 mm stroke, G3/8 port, and TC mounting accessory. The SAI family also adds an upgraded piston seal and introduces SAIL and BSAI lock variants.
Because it is a double-rod cylinder, force is equal both ways: 2268 N at 0.5 MPa, 3175 N at 0.7 MPa, and 4082 N at 0.9 MPa. The operating speed is 30-800 mm/s. It uses a G3/8 air port, a Ø25 mm rod with an M20x1.5 thread, and 36 mm adjustable cushions.
