This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID160X80S, 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 SID160X80S
The AirTAC Airtac SID Series Double-Rod Cylinder SID160X80S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 80mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID160X80S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID160X80S
The AirTAC SID160X80S is a discontinued double-acting double-rod ISO 15552 cylinder where a rod exits both ends on one piston. This means both faces use the rod-side area, so push and pull force are equal at 9425 N @0.5 MPa, 13194 N @0.7 MPa, and 16964 N @0.9 MPa. The bore is 160 mm, the piston rod is Ø40 mm, and the air port is G3/4. The direct replacement is the SAID160X80S, sharing the same interface, stroke, and mounting.
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 rod rotation and lets the back rod carry a sensor cam or drive a second tool. This -S model has a piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SID Series Double-Rod Cylinder SID160X80S Is Used
Dual-End Tooling Drive
Drives two opposing tools simultaneously from a single piston, utilizing the equal both-ways force to ensure perfectly synchronized machining or forming operations.
Anti-Rotation Transfer
Transfers heavy workpieces along a conveyor without rotational drift, relying on the rigid double-rod construction to maintain precise alignment.
Symmetric Lift Station
Lifts and lowers a 480 kg vertical payload using both rod ends to balance the load structure, achieving stable deceleration via the 50 mm adjustable cushions.
Replacing the Airtac SID Series Double-Rod Cylinder SID160X80S with the SAID160X80S
To replace the discontinued SID160X80S, specify the SAID160X80S; it is a direct swap retaining the ISO 15552 mounting interface, 80 mm stroke, G3/4 port, and M36x2 rod thread. Size both ways by checking equal force: this 160 mm bore delivers 9425 N @0.5 MPa, so if you need less force, step down to a 125 mm bore (5734 N @0.5 MPa), or step up to a 200 mm bore (15080 N @0.5 MPa) for more power. Choose a double-rod cylinder when you need anti-rotation stability or synchronized dual-end actuation. Mounting options include Basic, FA, LB, and TC. Keep the -S suffix for the piston magnet. For stroke lengths of 300 mm or longer, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID160X80S
- ✓ 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 SID160X80S FAQ
Yes, the SID160X80S is discontinued. The direct replacement is the SAID160X80S. It shares the same ISO 15552 interface, 160 mm bore, 80 mm stroke, G3/4 port, and mounting options, while adding an upgraded piston seal.
Force is equal both ways: 9425 N @0.5 MPa, 13194 N @0.7 MPa, and 16964 N @0.9 MPa. The air port is G3/4, the rod thread is M36x2, and speed ranges 30-500 mm/s. Note that air cushions only decelerate near stroke end; for load holding on air loss, use an external rod lock or SAIL/BSAI variant.
