This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID80X80S, 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 SID80X80S
The AirTAC Airtac SID Series Double-Rod Cylinder SID80X80S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 80mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID80X80S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID80X80S
The AirTAC SID80X80S 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 both ways at 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. The bore dictates a G3/8 air port, a 25 mm rod with an M20x1.5 thread, and 36 mm adjustable air cushions at each end. This SID model is discontinued and the direct replacement is the SAID80X80S, retaining the same interface, stroke, and mounting. The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life.
Because the second rod resists torsional side-load (anti-rotation) and can carry a sensor cam, it suits multi-tool drives. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. Note that air cushions only decelerate near stroke end; a plain cylinder does not hold loads on air loss, so use an external rod lock or SAIL/BSAI variant for holding.

Where the Airtac SID Series Double-Rod Cylinder SID80X80S Is Used
Twin-Tool Synchronization
Drives two opposing forming tools simultaneously from one piston, utilizing the equal push and pull force on both rod ends for matched timing.
Anti-Rotation Diverter
The dual-rod geometry prevents torsional twist during lateral package diversion on high-speed belts, maintaining precise routing without external guides.
Symmetric Lift Station
Lifts and lowers a 116 kg vertical load platform using equal both-ways force, with the rear rod carrying a sensor cam to confirm stroke endpoints.
Replacing the Airtac SID Series Double-Rod Cylinder SID80X80S with the SAID80X80S
To replace the discontinued SID80X80S, specify the SAID80X80S direct directly, matching the 80 mm bore, 80 mm stroke, G3/8 port, and ISO 15552 mounting. Size both ways using the equal-both-ways force (2268 N @0.5 MPa), checking neighbour bores if you need more or less power. A double rod is right when you need anti-rotation or a back rod to drive a second tool. Reuse FA, LB, or TC mounts. The -S magnet enables legacy CS1-B/DS1-B sensors. For this 80 mm stroke, side-load is minimal, but for stroke >=300 mm ensure guide alignment to prevent binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID80X80S
- ✓ 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 SID80X80S FAQ
Yes, the SID80X80S is discontinued. The direct replacement is the SAID80X80S, which shares the same ISO 15552 mounting interface, 80 mm bore, 80 mm stroke, G3/8 port, and equal-both-ways force. The SAI family also adds an upgraded piston seal and SAIL/BSAI lock variants.
Because it is a double-rod cylinder, force is equal both ways: 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. The bore sets the air port at G3/8, the piston rod at 25 mm with an M20x1.5 thread, and adjustable cushioning at 36 mm per end. Speed is 30-800 mm/s.
