This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID32X160, 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 SID32X160
The AirTAC Airtac SID Series Double-Rod Cylinder SID32X160 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 160mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID32X160, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID32X160
The AirTAC SID32X160 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, so push and pull force are equal at 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. This model is discontinued and end-of-life. The direct replacement is the SAID32X160, matching the 32mm bore, 160mm stroke, G1/8 port, and ISO 15552 mounting interface.
The SAI replacement uses an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. A double-rod design prevents piston rotation and lets the back rod carry a sensor cam or drive a second tool. This non-magnetic SKU cannot take a switch. A plain cylinder drifts on air loss; the 27mm adjustable cushion only decelerates near stroke end, so use an external rod lock for held loads.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |

Where the Airtac SID Series Double-Rod Cylinder SID32X160 Is Used
Dual-Tool Machining
Drives two opposing tool heads simultaneously with equal 483 N @0.7 MPa force in both directions, ensuring balanced material removal without stroke asymmetry.
Anti-Rotation Transfer
Transfers workpieces along a conveyor using the dual-rod architecture to prevent piston rotation, maintaining precise alignment during dynamic 30-800 mm/s movements.
External Cam Actuation
Uses the rear rod extension to trigger external mechanical limit cams or secondary mechanisms, keeping the primary 160mm stroke focused on the main work action.
Replacing the Airtac SID Series Double-Rod Cylinder SID32X160 with the SAID32X160
Replace the discontinued SID32X160 directly with the SAID32X160, reusing the exact ISO 15552 mounting interface (Basic, FA, LB, TC). Size both ways by verifying the equal push/pull force against neighbor bores; if 345 N @0.5 MPa is insufficient, step up to the 40mm bore. Choose a double-rod cylinder when anti-rotation is needed or when driving two tools simultaneously. This SKU lacks the -S magnet and cannot support sensing. For stroke lengths of 300mm or greater, verify side-load limits to prevent guide wear. Note that the G1/8 port is fixed by the 32mm bore.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID32X160
- ✓ 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 SID32X160 FAQ
Yes, the SID32X160 is discontinued. The direct replacement is the SAID32X160, which shares the same ISO 15552 mounting interface, 32mm bore, 160mm stroke, G1/8 port, and equal both-ways force.
Force is equal both ways (push and pull) because both faces use the rod-side area: 345 N @0.5 MPa, 483 N @0.7 MPa, and 621 N @0.9 MPa. The air port is G1/8, the rod is Ø12mm with an M10x1.25 thread, and speed is 30-800 mm/s.
