This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID200X80, 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 SID200X80
The AirTAC Airtac SID Series Double-Rod Cylinder SID200X80 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 80mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID200X80, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID200X80
The AirTAC SID200X80 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston, ensuring push and pull force is equal both ways. This unit is discontinued and drops directly into the exact same mounting interface as the SAID200X80. It features a 200mm bore, a 40mm piston rod, M36x2 rod-end thread, a G3/4 air port, and 50mm adjustable air cushions at each end. Because this SKU lacks a -S magnet, it cannot accept a magnetic piston switch.
The SAI replacement upgrades the piston seal with two Y-shaped one-way elements for low start-up pressure and long life, while keeping the 30-500 mm/s speed and 0.15-1.0 MPa operating pressure. A plain cylinder does not hold loads on air loss; the cushion only decelerates near stroke end, so use an external rod lock for held loads.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAID200X80 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |
| Max (@1.0 MPa) | 3204 kgf | |
The SAID200X80 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 SID200X80 Is Used
Equal-Force Pressing
Drives a double-ended forming station where the 21110 N @0.7 MPa force must remain identical in both advance and retract directions.
Dual-Side Transfer
Uses the second protruding rod to push a parallel conveyor lane simultaneously, keeping multi-track packaging perfectly synchronized.
Replacing the Airtac SID Series Double-Rod Cylinder SID200X80 with the SAID200X80
To replace the discontinued SID200X80, install the direct replacement SAID200X80, which matches the 80mm stroke, 200mm bore, G3/4 port, and ISO 15552 mounting dimensions (Basic, FA, LB, TC). Select a double-rod cylinder when you need equal force both ways or require an anti-rotation mechanism. If 15080 N is excessive, step down to the 160mm bore (9425 N @0.5 MPa); if more force is needed, confirm from datasheet as 200mm is the largest. This non-magnetic SKU cannot use sensors; for position feedback, choose an -S magnet model. Because the stroke is under 300mm, side-load leverage is minimal, but always verify guide alignment.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID200X80
- ✓ 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 SID200X80 FAQ
Yes, the SID200X80 is discontinued. The direct replacement is the SAID200X80, which shares the same ISO 15552 mounting interface, 200mm bore, 80mm stroke, G3/4 port, and equal both-ways force.
Because it is a double-rod cylinder, force is equal both ways: 15080 N @0.5 MPa, 21110 N @0.7 MPa, and 27141 N @0.9 MPa. The fixed air port size for the 200mm bore is G3/4.
