This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID160X300H, 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 SID160X300H
The AirTAC Airtac SID Series Double-Rod Cylinder SID160X300H 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 SAID160X300H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID160X300H
The AirTAC SID160X300H is a discontinued double-acting, double-rod ISO 15552 cylinder featuring a 160mm bore and 300mm stroke. Because a 40mm rod exits both ends on one piston, both faces use the rod-side area, making push and pull force equal at 9425N @0.5MPa, 13194N @0.7MPa, and 16964N @0.9MPa. The direct replacement is the SAID160X300H, matching the G3/4 port, M36x2 thread, and 50mm cushions. This -H variant uses Viton/FKM seals for 0 to 150C high-temp environments. Lacking a -S suffix, this SKU has no magnet and cannot take a sensor.
The SAI upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. A plain cylinder does not hold loads on air loss; the cushion only decelerates near stroke end. For held loads use an external rod lock or SAIL/BSAI variant. The double rod prevents rotation and can drive two tools.

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 SID160X300H Is Used
High-Temperature Press Tooling
Drives dual forming tools from both ends in a 150C thermal press, utilizing the Viton H seals and equal both-ways force for stable, synchronized actuation.
Heavy Transfer Diversion
Shifts large pallets sideways using the 160mm bore's 9425N @0.5MPa force, where the twin rods prevent chassis twist and maintain alignment under heavy lateral stress.
Replacing the Airtac SID Series Double-Rod Cylinder SID160X300H with the SAID160X300H
Replace the discontinued SID160X300H directly with the SAID160X300H, reusing the exact ISO 15552 mounting interface (Basic, FA, LB, TC) and G3/4 port. Size both ways by checking equal force across neighbor bores (125mm yields 5734N @0.5MPa; 200mm yields 15080N @0.5MPa). Choose a double-rod cylinder when you need anti-rotation stability or must drive two tools simultaneously. For the 300mm stroke, add external guides to prevent rod bending under side-loads. Note this non-magnetic SKU cannot support sensors; if sensing is needed, select a -S model. Operating pressure is 0.15-1.0MPa, speed is 30-500mm/s.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID160X300H
- ✓ 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 SID160X300H FAQ
Yes, the SID160X300H is discontinued. The direct replacement is the SAID160X300H. It shares the same ISO 15552 interface, 160mm bore, 300mm stroke, G3/4 port, and 50mm cushions, but adds an upgraded two Y-shaped one-way piston seal for longer life.
Force is equal both ways at 9425N @0.5MPa, 13194N @0.7MPa, and 16964N @0.9MPa. Operating pressure is 0.15-1.0MPa. Speed is 30-500mm/s. The G3/4 port and M36x2 rod thread are fixed by the bore. A plain cylinder does not hold loads on air loss; use an external rod lock or SAIL/BSAI variant for held loads.
