This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID200X200, 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 SID200X200
The AirTAC Airtac SID Series Double-Rod Cylinder SID200X200 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 200mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID200X200, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID200X200
The AirTAC SID200X200 is a discontinued double-acting double-rod ISO 15552 cylinder where a rod exits both ends, yielding equal force both ways (15080N at 0.5MPa, 21110N at 0.7MPa, 27141N at 0.9MPa). It features a 200mm bore, a 40mm rod, M36x2 rod threads, and a G3/4 air port. The direct replacement is the SAID200X200, which matches the stroke, mounting interface, and porting while upgrading to a two Y-shaped one-way piston seal for lower start-up pressure and longer life.
Because the piston has rods on both faces, push and pull forces are identical, preventing single-rod push asymmetry. This configuration provides inherent anti-rotation resistance and allows the back rod to drive a second tool. Without a -S suffix, this SKU lacks a magnet and cannot accept reed switches. Note that air cushions only decelerate; for load holding on air loss, use an external rod lock or the SAIL/BSAI lock variants.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |

Where the Airtac SID Series Double-Rod Cylinder SID200X200 Is Used
Tandem Press Drive
Uses the equal 27141N force both ways to drive two opposing press tools simultaneously, eliminating single-rod push asymmetry.
Anti-Rotation Transfer
Leverages the dual-rod architecture to push heavy pallets along a conveyor without rotational drift or requiring external guides.
Vertical Lift Station
Lifts loads up to the 769kg vertical limit safely, relying on the 200mm bore and 40mm rods for stable, balanced vertical motion.
Replacing the Airtac SID Series Double-Rod Cylinder SID200X200 with the SAID200X200
To replace the discontinued SID200X200, install the SAID200X200 directly; it preserves the ISO 15552 mounting interface, 200mm stroke, G3/4 port, and equal-both-ways force. When sizing both ways, verify that your load requires 15080N at 0.5MPa or 27141N at 0.9MPa, stepping to neighbour bores if higher force is needed. A double rod is right when you need anti-rotation stability or must drive two tools simultaneously. Mounting options include Basic, FA, LB, and TC. Because this SKU lacks the -S magnet, it cannot use sensors. For stroke lengths of 300mm or more, carefully manage side-load alignment to prevent premature seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID200X200
- ✓ 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 SID200X200 FAQ
Yes, the SID200X200 is discontinued. The direct replacement is the SAID200X200, which matches the ISO 15552 interface, 200mm bore, stroke, G3/4 port, and equal-both-ways force, while adding an upgraded piston seal.
The G3/4 ported 200mm bore provides equal force both ways: 15080N at 0.5MPa, 21110N at 0.7MPa, and 27141N at 0.9MPa.
