This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID80X1000S, 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 SID80X1000S
The AirTAC Airtac SID Series Double-Rod Cylinder SID80X1000S 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 SAID80X1000S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID80X1000S
The AirTAC SID80X1000S 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 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. This unit is discontinued; the direct replacement is the SAID80X1000S, matching the 80mm bore, 1000mm stroke, G3/8 port, M20x1.5 rod thread, and ISO 15552 mounting interface. The SAI upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life.
Because the second rod drives a sensor cam or two tools while resisting rotation, the design suits multi-tool stations. The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B switches. A plain cylinder does not hold loads on air loss; the 36mm adjustable cushions only decelerate near stroke end, so use an external rod lock 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 SAID80X1000S 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 SID80X1000S Is Used
Dual-Tool Machining Station
Drives two opposing machining heads simultaneously with equal push and pull force, ensuring balanced cutting cycles without requiring separate actuators.
Anti-Rotation Transfer Unit
Uses the twin-rod architecture to prevent mechanical rotation during long 1000mm transfers of heavy workpieces along an assembly conveyor.
Symmetric Clamping Fixture
Clamps components from both ends with identical 2268 N @0.5 MPa force, keeping delicate parts centered during secondary machining operations.
Replacing the Airtac SID Series Double-Rod Cylinder SID80X1000S with the SAID80X1000S
To replace the discontinued SID80X1000S, install the SAID80X1000S direct: it preserves the ISO 15552 interface, 1000mm stroke, G3/8 port, and 3175 N @0.7 MPa equal-both-ways force. Size both ways by checking neighbour bores (63mm yields 1962 N, 100mm yields 5153 N @0.7) to match your push and pull requirements. Choose a double-rod cylinder when you need anti-rotation, a back rod for a sensor cam, or to drive two tools. Mounting uses Basic, FA, LB, or TC styles. The -S magnet works with legacy CS1-B/DS1-B switches. For this 1000mm stroke, add external guides to prevent rod bending under side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID80X1000S
- ✓ 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 SID80X1000S FAQ
Yes, the SID80X1000S is discontinued. The direct replacement is the SAID80X1000S. It shares the same ISO 15552 mounting interface, 80mm bore, 1000mm stroke, G3/8 port, and equal-both-ways force, while adding an upgraded two Y-shaped one-way piston seal.
The G3/8 port feeds a double-acting double-rod design where force is equal both ways: 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. The 25mm rod uses an M20x1.5 thread, speed is 30-800 mm/s, and adjustable cushions are 36mm at each end.
