This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID100X180S, 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 SID100X180S
The AirTAC Airtac SID Series Double-Rod Cylinder SID100X180S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 180mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID100X180S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID100X180S
The AirTAC SID100X180S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston, ensuring push and pull force are equal at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. This model is discontinued. The direct replacement is the SAID100X180S, matching the 100mm bore, 180mm stroke, G1/2 port, M20x1.5 rod thread, and 36mm adjustable cushion. The SAI upgrade uses a two Y-shaped one-way piston seal for lower start-up pressure and longer life.
Because both faces use the rod-side area, the back rod can carry a sensor cam or drive two tools while resisting rotation. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. Note that air cushions only decelerate; an external rod lock or SAIL/BSAI variant is required to hold loads on air loss.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAID100X180S 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 SID100X180S Is Used
Dual-Tool Synchronized Driving
Drives two separate workstations simultaneously from one piston, utilizing the equal push/pull force on both rod ends to maintain perfectly synchronized machining cycles.
Anti-Rotation Transfer Unit
Transfers heavy pallets along a conveyor without rotational drift, using the inherent anti-rotation properties of the twin-rod ISO 15552 profile to avoid guide binding.
Replacing the Airtac SID Series Double-Rod Cylinder SID100X180S with the SAID100X180S
To replace the discontinued SID100X180S, swap in the SAID100X180S directly—it reuses the exact ISO 15552 mounting interface (Basic, FA, LB, TC) and G1/2 port. Size both directions by the equal-both-ways force: if 5153 N @0.7 MPa is insufficient, step up to bore 125 (8028 N); if oversized, step down to bore 80 (3175 N). A double-rod design is right when you need anti-rotation stability or synchronized two-tool driving. Keep the -S magnet for sensor mounting. For this 180mm stroke, side-load is minimal, but for any stroke >=300mm ensure guide alignment to prevent binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID100X180S
- ✓ 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 SID100X180S FAQ
Yes, the SID100X180S is discontinued. The direct replacement is the SAID100X180S. It shares the same ISO 15552 mounting interface, 100mm bore, 180mm stroke, G1/2 port, and force ratings, while adding an upgraded two Y-shaped one-way piston seal for longer life.
Force is equal both ways at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The air port is G1/2, speed is 30-800 mm/s, and it features a 25mm rod with M20x1.5 thread. Air cushions (36mm) only decelerate; use an external rod lock or SAIL/BSAI variant to hold loads.
