This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID80X100TC, 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 SID80X100TC
The AirTAC Airtac SID Series Double-Rod Cylinder SID80X100TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 100mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID80X100TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID80X100TC
The AirTAC SID80X100TC is a discontinued double-acting, double-rod ISO 15552 cylinder where a rod exits both ends on one piston. This geometry means both faces use the rod-side area, making push and pull force equal at 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. It features an 80mm bore, G3/8 port, M20x1.5 rod thread, and 36mm adjustable air cushions. The direct replacement is the SAID80X100TC, which shares the same interface, bore, stroke, and TC mount.
Because the second rod prevents piston rotation and can carry a sensor cam or drive a second tool, this design suits synchronized gripping. The SAI upgrade uses a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note this SKU lacks the -S magnet and cannot take a switch. A plain cylinder drifts on air loss; cushions only decelerate, so use an external rod lock or SAIL/BSAI variant for held loads.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |

Where the Airtac SID Series Double-Rod Cylinder SID80X100TC Is Used
Synchronized Workholding
Uses the dual opposing rods to drive two clamping jaws simultaneously with identical equal-both-ways force, ensuring balanced grip on machined parts.
Transfer Pushers
The second rod prevents piston rotation during rapid part ejection on packaging lines, maintaining precise alignment without lateral drift.
Replacing the Airtac SID Series Double-Rod Cylinder SID80X100TC with the SAID80X100TC
To replace the discontinued SID80X100TC, install the direct replacement SAID80X100TC, matching the 80mm bore, 100mm stroke, G3/8 port, and TC mounting interface. When sizing, verify equal both-ways force is sufficient; if more force is needed, step up to the 100mm bore (3681 N @0.5 MPa), or drop to 63mm (1402 N @0.5 MPa) for lighter duties. Choose a double-rod cylinder when you need anti-rotation, a back rod for a sensor cam, or to drive two tools. The TC mount provides a center trunnion pivot for articulated loads. This non-magnetic SKU cannot take a switch; add the -S suffix on the SAID for legacy CS1-B/DS1-B sensor accuracy. For strokes >=300mm, ensure side-load alignment to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID80X100TC
- ✓ 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 SID80X100TC FAQ
Yes, the SID80X100TC is discontinued. The direct replacement is the SAID80X100TC, sharing the same ISO 15552 interface, 80mm bore, 100mm stroke, G3/8 port, and TC mount. The SAI family also adds SAIL and BSAI lock variants the SI line lacked.
Force is equal both ways: 2268 N @0.5 MPa, 3175 N @0.7 MPa, and 4082 N @0.9 MPa. Speed is 30-800 mm/s. Note that air cushions only decelerate near stroke end; they do not hold the load on air loss.
