Airtac JSID Double Rod Cylinder JSID80X350S
The AirTAC Airtac JSID Double Rod Cylinder JSID80X350S is a genuine double acting, double rod JIS-standard air cylinder with a Ø80mm bore and 350mm stroke, G3/8 air ports and adjustable end cushioning. Its no-tie-rod, hard-anodized profile barrel is more compact than an ISO 15552 cylinder of the same bore — a space-saver on tight machines.

About the Airtac JSID Double Rod Cylinder JSID80X350S
Delivering 2268 N of thrust in both directions at 0.5 MPa, this 80 mm bore double-rod actuator uses a single piston with a rod exiting each cover to guarantee symmetric, equal force. The hard-anodized extruded aluminum profile makes it shorter and more compact than a same-bore ISO 15552 cylinder, while the G3/8 port handles the required airflow. A rod out both ends prevents rotation and allows driving two mechanisms simultaneously.
With the built-in magnet (-S), you can fit CMSE or DMSE sensors directly into the side grooves to track both ends of travel. This bore yields a safe working load of about 1361 N, capable of a 116 kg vertical lift with a 2:1 margin. The 29 mm adjustable air cushions at each end absorb kinetic energy near stroke end, though a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve for secure load holding.

Theoretical Output Force (Ø80mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | 3175 N |

Where the Airtac JSID Double Rod Cylinder JSID80X350S Is Used
Dual-End Transfer Pusher
Uses the protruding rod at the back to mount a sensor cam while the front rod pushes parts down a parallel conveyor lane.
Balanced Lift Station
Lifts and lowers a 116 kg platen with equal force both ways, relying on the symmetric load path to prevent guide binding.
Twin-Side Forming Press
Drives two small forming tools simultaneously from opposite ends of the piston for synchronized part shaping.
Is the Airtac JSID Double Rod Cylinder JSID80X350S the Right Cylinder?
When sizing this 80 mm model, step down to the 63 mm bore for 1402 N equal force, or step up to the 100 mm bore for 3574 N. Choose a double-rod configuration when your mechanism demands anti-rotation guidance, symmetric load paths, or twin tooling driven from one piston. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. The -S suffix ensures you have the magnet ready for CMSE/DMSE switches. Because the 350 mm stroke is substantial, always support the load with external guides to prevent rod bending and excessive side loading.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac JSID Double Rod Cylinder JSID80X350S FAQ
Force is equal in both directions at 2268 N at 0.5 MPa and 3175 N at 0.7 MPa, with a theoretical max of 463 kgf at 1.0 MPa. It uses a G3/8 air port and features an M22x1.5 rod-end thread.
The dual-rod design prevents piston rotation and provides a symmetric load path for twin tooling or back-end cam actuation. The -S option includes a piston magnet for CMSE or DMSE reed and electronic sensors that mount directly into the barrel grooves.
