This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID160X200, 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 SID160X200
The AirTAC Airtac SID Series Double-Rod Cylinder SID160X200 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 200mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID160X200, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID160X200
The AirTAC SID160X200 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston, ensuring push and pull force are equal at 9425 N @0.5 MPa, 13194 N @0.7 MPa, and 16964 N @0.9 MPa. This SKU is discontinued and end-of-life; the direct replacement is the SAID160X200, which retains the same 160mm bore, 200mm stroke, G3/4 air port, M36x2 rod thread, and mounting interface. The SAI upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life.
With a 40mm piston rod and 50mm adjustable air cushions at each end, operating speed is 30-500 mm/s. This non-magnet version cannot take a sensor. A plain cylinder does not hold loads on air loss; cushions only decelerate near stroke end, so use an external rod lock or SAIL/BSAI variant for held loads.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |

Where the Airtac SID Series Double-Rod Cylinder SID160X200 Is Used
Dual-Tool Transfer
Drives two opposing grippers simultaneously on a conveyor line, utilizing the equal both-ways force to push and pull parts with identical 9425 N @0.5 MPa authority.
Anti-Rotation Lift
Lifts a 480 kg vertical payload using the twin rods to prevent torsional twist and binding, maintaining precise guidance without external linear bearings.
Balanced Press Module
Applies equal clamping pressure from both ends of a press fixture, leveraging the 50mm adjustable cushions to decelerate heavy 160mm bores smoothly at 30-500 mm/s.
Replacing the Airtac SID Series Double-Rod Cylinder SID160X200 with the SAID160X200
To replace the discontinued SID160X200, swap in the SAID160X200 directly; it preserves the ISO 15552 mounting interface so existing FA, LB, or TC brackets bolt straight on. Size both ways by checking equal force: this 160mm bore delivers 9425 N @0.5 MPa, so if you need less, the 125mm bore gives 5734 N, and if you need more, the 200mm bore yields 15080 N. A double-rod design is right when you need anti-rotation stability or want to drive two tools from one piston. Because this specific SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors; confirm if you need the -S option. For stroke lengths >=300, verify your side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID160X200
- ✓ 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 SID160X200 FAQ
Yes, the SID160X200 is discontinued. The direct replacement is the SAID160X200. It shares the same ISO 15552 interface, 160mm bore, 200mm stroke, G3/4 port, and mounting options, while adding an upgraded two Y-shaped one-way piston seal for longer life.
Force is equal both ways at 9425 N @0.5 MPa, 13194 N @0.7 MPa, and 16964 N @0.9 MPa. The air port is G3/4, the rod thread is M36x2, and speed is 30-500 mm/s. It operates at 0.15-1.0 MPa with 50mm adjustable cushions.
