This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID160X75S, 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 SID160X75S
The AirTAC Airtac SID Series Double-Rod Cylinder SID160X75S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 75mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID160X75S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID160X75S
The AirTAC SID160X75S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston. This configuration 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 bore is 160 mm, the rod is Ø40 mm with an M36x2 thread, the air port is G3/4, and adjustable air cushions are 50 mm at each end. This SID model is discontinued; the direct replacement is the SAID160X75S, which retains the same ISO 15552 interface, stroke, and mounting.
The SAI upgrade uses an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The -S suffix indicates 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. For held loads, use an external rod lock or SAIL/BSAI variant.

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 SAID160X75S 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 SID160X75S Is Used
Twin-Tool Machining Station
Drives two opposing machining heads simultaneously from one piston, utilizing the equal both ways force to maintain perfectly synchronized cutting cycles.
Anti-Rotation Transfer Pusher
The dual-rod geometry prevents twist during high-thrust horizontal transfers, keeping heavy workpieces aligned on the conveyor belt without external guides.
Symmetric Pallet Lift
Lifts palletized loads vertically using the back rod as a sensor cam target, ensuring precise height detection while the front rod performs the lifting work.
Replacing the Airtac SID Series Double-Rod Cylinder SID160X75S with the SAID160X75S
To replace the discontinued SID160X75S, install the direct replacement SAID160X75S, which matches the 160 mm bore, 75 mm stroke, G3/4 port, and ISO 15552 mounting. Size both ways by checking equal force across neighbor bores: the 125 mm bore yields 5734 N @0.5 MPa, while the 200 mm bore yields 15080 N @0.5 MPa. A double rod is right when you need anti-rotation stability or want to drive two tools from one piston. Reuse FA, LB, or TC mounts. The -S magnet enables legacy CS1-B/DS1-B sensors. For this 75 mm stroke, side-load is minimal, but for strokes >=300 mm, verify guide alignment to prevent binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID160X75S
- ✓ 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 SID160X75S FAQ
Yes, the SID160X75S is discontinued. The direct replacement is the SAID160X75S. It shares the same ISO 15552 interface, 160 mm bore, 75 mm stroke, G3/4 port, and mounting hardware, but features an upgraded piston seal for longer life.
Because it is double-acting double-rod, force is equal both ways: 9425 N @0.5 MPa, 13194 N @0.7 MPa, and 16964 N @0.9 MPa. Speed is 30-500 mm/s. It operates at 0.15-1.0 MPa with a 50 mm adjustable cushion at each end.
