This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID160X100, 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 SID160X100
The AirTAC Airtac SID Series Double-Rod Cylinder SID160X100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 100mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID160X100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID160X100
The AirTAC SID160X100 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, ensuring push and pull force is equal both ways (9425 N @0.5 MPa). This SKU has no -S magnet and cannot accept a sensor. AirTAC has discontinued the SID line; the direct replacement is the SAID160X100, retaining the G3/4 port, M36x2 rod thread, and 50 mm cushion. The SAI family uses an upgraded two-piece Y-shaped piston seal for lower start-up pressure.
Because both faces use the identical rod-side area, you gain equal both-ways force for driving two tools or anti-rotation stability. Note that 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 the SAIL/BSAI lock 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 SAID160X100 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 SID160X100 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 Unit
The dual exiting rods prevent mechanical rotation during heavy part transfers across a conveyor, ensuring precise placement without external linear guides.
Balanced Vertical Lift Gate
Lifts a 480 kg materials gate using the equal pull force on both faces, providing stable vertical motion without the asymmetry of single-rod designs.
Replacing the Airtac SID Series Double-Rod Cylinder SID160X100 with the SAID160X100
To replace the discontinued SID160X100, swap it directly for the SAID160X100; the ISO 15552 mounting interface and FA, LB, and TC foot/tap brackets reuse existing holes without machining. Size both ways by checking neighbour bores if you need less force, but the 160 mm bore delivers identical push and pull (9425 N @0.5 MPa, 13194 N @0.7 MPa). Choose a double-rod cylinder when you need anti-rotation resistance or must drive two mechanisms. This non-magnetic SKU cannot take a switch. For this 100 mm stroke, side-load is minimal, but for any stroke >=300 mm, ensure guide alignment to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID160X100
- ✓ 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 SID160X100 FAQ
Yes, the SID160X100 is discontinued. The direct replacement is the SAID160X100. It shares the same ISO 15552 interface, 160 mm bore, 100 mm stroke, G3/4 port, and mounting dimensions, while adding an upgraded piston seal.
Force is equal both ways at 9425 N @0.5 MPa, 13194 N @0.7 MPa, and 16964 N @0.9 MPa. The bore dictates a fixed G3/4 air port, a 40 mm rod with an M36x2 thread, 50 mm adjustable cushions, and a 30-500 mm/s speed range.
