This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID100X75S, 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 SID100X75S
The AirTAC Airtac SID Series Double-Rod Cylinder SID100X75S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 75mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID100X75S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID100X75S
The AirTAC SID100X75S is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston. Because both faces use the rod-side area, push and pull force are equal at 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. The bore is 100 mm, the port is G1/2, the rod thread is M20x1.5, and adjustable air cushions are 36 mm at each end. This SID model is discontinued; the direct replacement is the SAID100X75S, which retains the same ISO 15552 mounting interface, bore, stroke, and port.
The SAI replacement uses an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. A double-rod design prevents rotation and lets the back rod carry a sensor cam or drive a second tool. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches. A plain cylinder drifts on air loss since the cushion only decelerates; use an external rod lock or SAIL/BSAI variant for held loads.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac SID Series Double-Rod Cylinder SID100X75S Is Used
Dual-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
Moves a gripping fixture along a conveyor line where the twin rods prevent rotational twist, ensuring the payload remains perfectly aligned during transit.
Symmetric Sorting Diverter
Actuates a diverter arm from the rear rod end to mount a legacy CS1-B/DS1-B sensor cam externally, keeping the primary push path clear for package sorting.
Replacing the Airtac SID Series Double-Rod Cylinder SID100X75S with the SAID100X75S
To replace the discontinued SID100X75S, install the direct replacement SAID100X75S, which matches the 100 mm bore, 75 mm stroke, G1/2 port, and ISO 15552 mounting footprint. Size both directions by the equal-both-ways force: 3681 N @0.5, 5153 N @0.7, and 6626 N @0.9 MPa. If you need less force, the neighbouring 80 mm bore provides 2268 N @0.5 MPa; for more, the 125 mm bore offers 5734 N @0.5 MPa. A double rod is right when you need anti-rotation, a back-end sensor cam, or to drive two tools. Mounting options include Basic, FA, LB, and TC. The -S magnet supports legacy CS1-B/DS1-B sensors. For this 75 mm stroke, side-load is minimal, but for strokes >=300 mm, ensure guide alignment to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID100X75S
- ✓ 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 SID100X75S FAQ
Yes, the AirTAC SID100X75S is discontinued. The direct replacement is the SAID100X75S. It shares the same 100 mm bore, 75 mm stroke, G1/2 port, and ISO 15552 mounting interface, but features an upgraded two Y-shaped one-way piston seal for longer life.
Because it is a double-rod cylinder, force is equal both ways: 3681 N @0.5 MPa, 5153 N @0.7 MPa, and 6626 N @0.9 MPa. Operating speed is 30-800 mm/s.
