This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID100X150S, 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 SID100X150S
The AirTAC Airtac SID Series Double-Rod Cylinder SID100X150S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 150mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID100X150S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID100X150S
The AirTAC SID100X150S is a discontinued 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. The bore is 100 mm, stroke 150 mm, piston rod Ø25 mm, rod-end thread M20x1.5, and air port G1/2. It features a built-in piston magnet (-S) for legacy CS1-B/DS1-B switches. The direct replacement is the SAID100X150S, sharing the same interface, force, 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. A double-rod design prevents rod rotation and lets the back rod carry a sensor cam or drive a second tool. A plain cylinder does not hold loads on air loss; the 36 mm adjustable air cushions only decelerate near stroke end. For held loads, use an external rod lock or SAIL/BSAI variant.

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 SID100X150S Is Used
Dual-Tool Machining Station
Drives two opposing machining heads simultaneously from a single piston, utilizing the equal both-ways force to maintain perfectly synchronized feed rates on both ends.
Anti-Rotation Transfer Gate
Uses the twin-rod architecture to prevent rod twisting during high-speed package diversion, ensuring the guide mechanism remains perfectly aligned without external linear bearings.
Symmetric Lift Platform
Employs the rear rod extension to mount an external position cam while the front rod lifts the platform, keeping the 3681 N @0.5 MPa force balanced for stable vertical motion.
Replacing the Airtac SID Series Double-Rod Cylinder SID100X150S with the SAID100X150S
Replace the discontinued SID100X150S directly with the SAID100X150S, reusing the exact ISO 15552 mounting interface (Basic, FA, LB, TC, FTC, TCM1, TCM2) and G1/2 port. Size both directions by equal force: this 100 mm bore yields 3681 N @0.5 MPa both ways; if less force is needed, the 80 mm bore gives 2268 N, and the 125 mm bore gives 5734 N. A double rod is right when you need anti-rotation, a back-rod sensor cam, or dual-tool driving. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. For this 150 mm stroke, side-load alignment is generally manageable, but for any stroke >=300 mm, carefully calculate guide bearing loads to prevent premature wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID100X150S
- ✓ 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 SID100X150S FAQ
Yes, the SID100X150S is discontinued. The direct replacement is the SAID100X150S, which matches the 100 mm bore, 150 mm stroke, G1/2 port, and ISO 15552 mounting. The SAI family also adds upgraded piston seals and SAIL/BSAI lock variants the SI line lacked.
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. The air port is G1/2, the rod is Ø25 mm with an M20x1.5 thread, and speed is 30-800 mm/s. The cushions only decelerate; they do not hold loads on air loss.
