This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID160X175, 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 SID160X175
The AirTAC Airtac SID Series Double-Rod Cylinder SID160X175 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 175mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID160X175, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID160X175
The AirTAC SID160X175 is a double-acting double-rod ISO 15552 cylinder where a rod exits both ends, ensuring push and pull force are equal at 9425 N @0.5 MPa, 13194 N @0.7 MPa, and 16964 N @0.9 MPa. This discontinued 160mm bore model features a 40mm rod, M36x2 thread, 50mm adjustable cushions, G3/4 port, and operates at 30-500 mm/s. It cannot hold a load on air loss, as cushions only decelerate.
The direct replacement is the SAID160X175, reusing the same ISO 15552 mounting interface without requiring new brackets. The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. Without a -S suffix, this SKU cannot take a magnetic switch.

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 SAID160X175 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 SID160X175 Is Used
Twin-Tool Machining Station
Drives two opposing machining heads simultaneously with equal push and pull force, maintaining precise synchronization without requiring separate cylinders.
Anti-Rotation Transfer Unit
Uses the dual-rod architecture to prevent piston rotation during heavy lateral transfer tasks on a conveyor line, ensuring guided linear motion.
External Cam Positioning
Leverages the rear protruding rod to mechanically actuate an external cam or limit switch mechanism, independent of internal pneumatic sensing.
Replacing the Airtac SID Series Double-Rod Cylinder SID160X175 with the SAID160X175
Replace the discontinued SID160X175 directly with the SAID160X175, matching the 175mm stroke and equal both ways force. When sizing both ways, verify if a 125mm bore (5734 N @0.5) is sufficient or if the 200mm bore (15080 N @0.5) is required for higher demands. A double rod is right when you need anti-rotation stability or must drive two tools simultaneously. Reuse FA, LB, or TC mounts. Lacking a -S suffix means no sensor can be fitted. For stroke lengths >=300mm, verify side-load bearing limits. For held loads, use an external rod lock or SAIL/BSAI variant, as air cushions only decelerate.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID160X175
- ✓ 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 SID160X175 FAQ
Yes, the SID160X175 is discontinued. The direct replacement is the SAID160X175, which shares the identical ISO 15552 mounting interface, 160mm bore, 175mm stroke, G3/4 port, and equal both ways force.
Force is equal both ways: 9425 N @0.5 MPa, 13194 N @0.7 MPa, and 16964 N @0.9 MPa. The bore dictates a G3/4 air port. The cylinder operates at 30-500 mm/s and does not hold loads without live air.
