This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID160X150S, 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 SID160X150S
The AirTAC Airtac SID Series Double-Rod Cylinder SID160X150S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 150mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID160X150S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID160X150S
The AirTAC SID160X150S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston. This geometry means 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 SID160X150S is discontinued and replaced by the SAID160X150S. This direct SAI replacement shares the exact 160mm bore, 150mm stroke, G3/4 port, M36x2 rod thread, and 50mm adjustable cushion. The SAI family also uses an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life.
Because the second rod can carry a sensor cam or drive two tools while resisting rotation, the design suits high-precision tasks. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches. A plain cylinder does not hold loads on air loss; the cushion only decelerates near stroke end, so use an external rod lock or SAIL/BSAI variant for held loads.

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 SID160X150S Is Used
Twin-Tool Machining Station
Drives two opposing machining heads simultaneously with equal 13194 N force at 0.7 MPa, ensuring perfectly balanced material removal on both faces.
Anti-Rotation Transfer Unit
Uses the dual-rod geometry to prevent mechanical rotation during high-speed part transfers, maintaining strict alignment without external guides.
Symmetric Clamping Fixture
Clamps heavy workpieces from both sides using the equal push and pull force, with the rear rod actuating a secondary sensor cam for position verification.
Replacing the Airtac SID Series Double-Rod Cylinder SID160X150S with the SAID160X150S
To replace the discontinued SID160X150S, install the direct replacement SAID160X150S, which preserves the ISO 15552 mounting interface, 160mm bore, 150mm stroke, G3/4 port, and equal both-ways force. When sizing, verify both directions handle the load; if 9425 N @0.5 MPa is insufficient, step up to a 200mm bore, or drop to 125mm if lower force is acceptable. Choose a double-rod cylinder when you need anti-rotation stability, a back rod for a sensor cam, or to drive two tools simultaneously. Mounting options include Basic, FA, LB, and TC styles. The -S magnet supports legacy CS1-B/DS1-B switches. For this 150mm stroke, side-load is minimal, but for strokes >=300mm ensure guide alignment to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID160X150S
- ✓ 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 SID160X150S FAQ
Yes, the SID160X150S is discontinued. The direct replacement is the SAID160X150S. It shares the identical ISO 15552 interface, 160mm bore, 150mm stroke, G3/4 port, and mounting options, while adding an upgraded piston seal for longer life.
