This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID160X300SH, 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 SID160X300SH
The AirTAC Airtac SID Series Double-Rod Cylinder SID160X300SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 300mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID160X300SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID160X300SH
The AirTAC SID160X300SH is a double-acting, double-rod ISO 15552 cylinder that is officially discontinued. The direct replacement is the SAID160X300SH, matching the 160mm bore, 300mm stroke, G3/4 port, and mounting interface. Because a rod exits both ends on one piston, both faces use the rod-side area, making push and pull force equal at 9425 N @0.5 MPa, 13194 N @0.7 MPa, and 16964 N @0.9 MPa. The SAI upgrade uses an upgraded two Y-shaped one-way piston seal for low start-up pressure and long life. The -H Viton/FKM seal allows 0-150 C high-temp operation, and the -S magnet works with legacy CS1-B/DS1-B switches.
A double-rod design prevents rod-side rotation and lets the back rod carry a sensor cam or drive a second tool. A plain cylinder does not hold loads on air loss; the 50mm adjustable cushions only decelerate near stroke end. For held loads, use an external rod lock, pilot-operated check valve, or the SAIL/BSAI lock variants.

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 SID160X300SH Is Used
Tandem Press Drive
Drives two forming tools simultaneously from one piston, utilizing the equal 13194 N @0.7 MPa force in both directions for balanced, high-tonnage pressing.
Anti-Rotation Transfer
Moves heavy pallets laterally without rotational twist, using the dual 40mm rods to maintain precise alignment during 300mm index strokes.
High-Temp Ejection
Ejects cast parts from 0-150 C environments safely using the Viton H seal, while the rear rod mounts a cam to trigger external sequencing valves.
Replacing the Airtac SID Series Double-Rod Cylinder SID160X300SH with the SAID160X300SH
To replace the discontinued SID160X300SH, install the SAID160X300SH directly—it preserves the ISO 15552 mounting interface, 300mm stroke, and equal-both-ways force. Size both directions by checking neighboring bores (e.g., 125mm or 200mm) if you need to adjust the 9425 N @0.5 MPa baseline. Choose a double-rod cylinder when you need anti-rotation stability or want to drive two tools simultaneously. Reuse FA, LB, or TC mounts. The -S magnet enables CS1-B/DS1-B sensors (current AirTAC switches on SAI). For the 300mm stroke, add external guides to prevent rod bending under side loads. Remember, air cushions only decelerate; they do not hold loads without live air.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID160X300SH
- ✓ 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 SID160X300SH FAQ
Yes, the SID160X300SH is discontinued. The direct replacement is the SAID160X300SH. It shares the identical ISO 15552 interface, 160mm bore, 300mm stroke, G3/4 port, and equal-both-ways force, but adds an upgraded piston seal.
Force is equal both ways (push and pull) because both faces use the rod-side area: 9425 N @0.5 MPa, 13194 N @0.7 MPa, and 16964 N @0.9 MPa. The air port is G3/4, the rod is 40mm with an M36x2 thread, and speed is 30-500 mm/s.
