This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAID50X1000, 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 SID50X1000
The AirTAC Airtac SID Series Double-Rod Cylinder SID50X1000 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø50mm bore and 1000mm stroke, G1/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAID50X1000, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SID Series Double-Rod Cylinder SID50X1000
The AirTAC SID50X1000 is a double-acting, double-rod ISO 15552 cylinder where a rod exits both ends, ensuring force is equal both ways (825 N at 0.5 MPa). This discontinued model drops directly into the SAID50X1000, matching the 50mm bore, 1000mm stroke, G1/4 port, and mounting interface. The SAI upgrade uses two Y-shaped one-way piston seals for low start-up pressure and long life.
Because the rod-side area drives both faces, push and pull forces match exactly. This non-magnetic SKU cannot take a sensor. A plain cylinder drifts on air loss—cushions only decelerate—so use an external rod lock for held loads.

Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |

Where the Airtac SID Series Double-Rod Cylinder SID50X1000 Is Used
Synchronized Transfer
Drives two parallel conveyor lanes simultaneously using the opposing rod ends, maintaining equal force during transit.
Anti-Rotation Tooling
Powers a machining fixture where the dual rods prevent piston rotation, ensuring precise tool alignment over the 1000mm travel.
Replacing the Airtac SID Series Double-Rod Cylinder SID50X1000 with the SAID50X1000
Replace the SID50X1000 directly with the SAID50X1000, retaining the ISO 15552 mounting interface (Basic, FA, LB, TC) and the G1/4 port. Size both ways by checking neighbour bores: the 40mm yields 528 N, while the 63mm provides 1402 N at 0.5 MPa, both equal in push and pull. Choose a double-rod when you need anti-rotation stability or to drive two tools. As this non-magnetic SKU lacks a sensor cam, add an -S magnet if sensing is required. For the 1000mm stroke, use external guides to prevent rod bending under side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAID50X1000
- ✓ 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 SID50X1000 FAQ
Yes, the SID50X1000 is discontinued. The direct replacement is the SAID50X1000, which shares the same ISO 15552 interface, 50mm bore, 1000mm stroke, G1/4 port, and equal both-ways force.
Force is equal both ways: 825 N @0.5 MPa, 1154 N @0.7 MPa, and 1484 N @0.9 MPa. The air port is G1/4, the rod is Ø20 mm with an M16x1.5 thread, and it features 30mm adjustable air cushions at each end.
