This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID80X100, 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 SID80X100
The AirTAC Airtac SID Series Double-Rod Cylinder SID80X100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID80X100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID80X100
The AirTAC SID80X100 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 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. The bore sets the air port to G3/8, with an M20x1.5 rod thread and 36 mm adjustable cushions at each end. The direct replacement is the SAID80X100, retaining the same interface, port, and mounting.
Because this SKU lacks the -S magnet, it cannot take a magnetic switch. The SAI upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. A plain cylinder does not hold loads on air loss; the cushion only decelerates near stroke end. For held loads, use an external rod lock or the SAIL/BSAI lock variants.

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 SAID80X100 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 SID80X100 Is Used
Dual-Tool Machining Station
Drives two opposing machining heads from a single piston, ensuring perfectly synchronized contact with equal push and pull force on both ends.
Anti-Rotation Transfer Gate
Uses the twin-rod architecture to prevent mechanical twist during rapid part diversion on a 30-800 mm/s packaging line.
Symmetric Pallet Stopper
Extends a stopping blade through both end plates to absorb pallet impact equally, minimizing off-center side loading on the bearings.
Replacing the Airtac SID Series Double-Rod Cylinder SID80X100 with the SAID80X100
Replace the discontinued SID80X100 directly with the SAID80X100, matching the 80 mm bore, 100 mm stroke, G3/8 port, and ISO 15552 mounting. Size both ways by checking the equal push/pull force against your load; if 3175 N @0.7 MPa is insufficient, step up to the 100 mm bore, or drop to 63 mm if over-specified. Choose a double-rod cylinder when you need anti-rotation stability or must drive two tools from one piston. Reuse FA, LB, or TC mounts directly. This non-magnetic SKU cannot accept sensors; add the -S suffix on the SAID if you need legacy CS1-B/DS1-B switches. For strokes of 300 mm or longer, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID80X100
- ✓ 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 SID80X100 FAQ
Yes, the AirTAC SID80X100 is discontinued. The direct replacement is the SAID80X100. It shares the identical ISO 15552 mounting interface, 80 mm bore, 100 mm stroke, G3/8 port, and equal both-ways force, while adding an upgraded two Y-shaped one-way piston seal.
Force is equal both ways because the rod exits both ends: 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. The air port is G3/8, the rod thread is M20x1.5, and it has 36 mm adjustable cushions.
