This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID200X200S, 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 SID200X200S
The AirTAC Airtac SID Series Double-Rod Cylinder SID200X200S 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 SAID200X200S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID200X200S
The AirTAC SID200X200S is a discontinued ISO 15552 double-acting double-rod cylinder. A 40mm rod exits both ends on one piston, meaning both faces use the rod-side area and push/pull force is equal both ways (15080N at 0.5MPa, 21110N at 0.7MPa, 27141N at 0.9MPa). It features a G3/4 port, M36x2 rod thread, and 50mm adjustable cushions. The direct replacement is the SAID200X200S, matching the interface, stroke, and force.
The SAI upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. Double-rod benefits include anti-rotation and using the back rod to carry a sensor cam. The -S suffix denotes a piston magnet for legacy CS1-B/DS1-B switches; the SAI replacement uses current AirTAC switches.

Where the Airtac SID Series Double-Rod Cylinder SID200X200S Is Used
Twin-Tool Drive
Drives two independent work tools simultaneously from a single piston, utilizing the equal force from both rod ends for synchronized machining operations.
Anti-Rotation Transfer
Moves heavy pallets along a conveyor without rotational drift, using the inherent anti-rotation properties of the double-rod construction.
Symmetric Lift Station
Lifts vertical loads symmetrically using both rod ends, ensuring stable elevation of heavy materials without binding.
Replacing the Airtac SID Series Double-Rod Cylinder SID200X200S with the SAID200X200S
To replace the SID200X200S, order the SAID200X200S (insert A after the leading S). It is a direct: same 200mm bore, 200mm stroke, 15080N equal-both-ways force, G3/4 port, and ISO 15552 mounting (Basic, FA, LB, TC, FTC, TCM1, TCM2). When sizing both ways, verify the equal push/pull force covers your load; if 15080N at 0.5MPa is insufficient, the next bore up is required, or if excessive, step down to a neighbour bore. A double rod is right when you need anti-rotation or must drive two tools. Choose the -S option for the piston magnet. For stroke lengths >=300mm, verify side-load limits to prevent guide wear. A plain cylinder does not hold loads on air loss; use an external rod lock or SAIL/BSAI variant for held loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID200X200S
- ✓ 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 SID200X200S FAQ
Yes, the SID200X200S is discontinued. The direct replacement is the SAID200X200S. It shares the same ISO 15552 mounting interface, 200mm bore, 200mm stroke, G3/4 port, and equal both ways force, with an upgraded piston seal for longer life.
Because it is a double-rod cylinder, force is equal both ways: 15080N at 0.5MPa, 21110N at 0.7MPa, and 27141N at 0.9MPa. The air port is G3/4, the rod thread is M36x2, and it features 50mm adjustable cushions at each end. Speed range is 30-500mm/s.
