This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID200X160, 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 SID200X160
The AirTAC Airtac SID Series Double-Rod Cylinder SID200X160 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 160mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID200X160, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID200X160
The AirTAC SID200X160 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston. Both faces use the rod-side area, making push and pull force equal at 15080 N @0.5 MPa, 21110 N @0.7 MPa, and 27141 N @0.9 MPa. This SKU has no -S magnet and cannot take a sensor. It features a 40 mm rod, M36x2 thread, 50 mm adjustable cushion, G3/4 port, and 30-500 mm/s speed. The SID200X160 is discontinued; the direct replacement is the SAID200X160, sharing the exact bore, stroke, force, port, and ISO 15552 mounting interface.
The SAI upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life, adding SAIL and BSAI lock variants. A plain cylinder drifts on air loss; the cushion only decelerates near stroke end. For held loads, use an external rod lock, pilot-operated check valve, or SAIL/BSAI variant.

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 SAID200X160 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 SID200X160 Is Used
Equal-Force Pressing
Applies 21110 N @0.7 MPa identically on extension and retraction for double-sided forming or clamping stations.
Dual-Tool Transfer
The second rod end drives an independent gripper or cam on the opposite side, synchronizing two conveyor actions.
Replacing the Airtac SID Series Double-Rod Cylinder SID200X160 with the SAID200X160
To replace the discontinued SID200X160, install the SAID200X160 directly; it matches the ISO 15552 interface, G3/4 port, and 1500 mm max standard stroke. Size both ways by checking equal force: if 21110 N @0.7 MPa is excessive, step down to the 160 mm bore (13194 N). A double rod is right when you need equal both-ways force, anti-rotation stability, or a back rod to drive a second tool. Reuse FA, LB, or TC mounts. This SKU lacks the -S magnet, so it cannot support sensing. For this 160 mm stroke, side-load is minimal, but for strokes >=300 mm ensure guide alignment to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID200X160
- ✓ 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 SID200X160 FAQ
Yes, the SID200X160 is discontinued. The direct replacement is the SAID200X160, which shares the same ISO 15552 mounting interface, bore, stroke, G3/4 port, and equal both-ways force.
Force is equal both ways: 15080 N @0.5 MPa, 21110 N @0.7 MPa, and 27141 N @0.9 MPa. The air port is G3/4, the rod is 40 mm with an M36x2 thread, and speed is 30-500 mm/s.
