This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID160X800, 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 SID160X800
The AirTAC Airtac SID Series Double-Rod Cylinder SID160X800 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 800mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID160X800, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID160X800
The AirTAC SID160X800 is a double-acting double-rod ISO 15552 cylinder with an 800 mm stroke. Because a rod exits both ends, the effective piston area is identical in each direction, yielding equal push and pull force of 9425 N at 0.5 MPa, 13194 N at 0.7 MPa, and 16964 N at 0.9 MPa. The bore dictates a G3/4 port, an M36x2 rod thread, and 50 mm adjustable air cushions at each end. This legacy unit is discontinued; the direct replacement is the SAID160X800, which reuses the exact ISO 15552 mounting interface and porting.
The SAID upgrade introduces a two-piece Y-shaped one-way piston seal for lower start-up pressure and longer life. This non-magnetic SKU cannot accept a switch. Note that air cushions only decelerate the piston near stroke end; they do not hold loads on air loss, so an external rod lock or pilot-operated check valve is required for holding.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAID160X800 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 SID160X800 Is Used
Dual-End Transfer Pusher
Uses the extending rear rod to mount a sensor cam or secondary actuator while the front rod pushes heavy pallets along a conveyor line with equal push and pull stability.
Anti-Rotation Machining Clamp
Applies the equal-both-ways force to securely grip and release heavy castings inside a CNC mill, preventing rotational drift during aggressive metal removal.
Symmetrical Lift Fixture
Drives two opposing mechanical linkages simultaneously from a single piston, ensuring perfectly synchronized vertical movement of heavy storage trays.
Replacing the Airtac SID Series Double-Rod Cylinder SID160X800 with the SAID160X800
To replace the discontinued SID160X800, install the SAID160X800 directly—it matches the 160 mm bore, 800 mm stroke, G3/4 port, and ISO 15552 mounting dimensions. Size both directions by the equal-both-ways force: 9425 N at 0.5 MPa, stepping to the 200 mm bore if more thrust is needed, or down to 125 mm if less is required. A double rod is the right choice when you need anti-rotation stability, equal push/pull work, or a back rod to drive a second mechanism. Reuse FA, LB, or TC mounts. Because this unit lacks the -S magnet, it cannot carry a sensor. Finally, at 800 mm stroke, use external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID160X800
- ✓ 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 SID160X800 FAQ
Yes, the SID160X800 is discontinued. The direct replacement is the SAID160X800, which shares the same ISO 15552 mounting interface, 160 mm bore, 800 mm stroke, G3/4 port, and equal-both-ways force. The SAI family also adds upgraded Y-shaped piston seals and lock variants like SAIL and BSAI that the SI line lacked.
Force is equal both ways: 9425 N at 0.5 MPa, 13194 N at 0.7 MPa, and 16964 N at 0.9 MPa. It operates at 30-500 mm/s, features a 50 mm adjustable air cushion at each end, and uses a G3/4 port. The cushion only decelerates the piston near stroke end; it does not hold loads on air loss, so use an external rod lock for holding.
