Airtac JSID Double Rod Cylinder JSID80X70
The AirTAC Airtac JSID Double Rod Cylinder JSID80X70 is a genuine double acting, double rod JIS-standard air cylinder with a Ø80mm bore and 70mm 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 JSID80X70
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 end. The symmetric layout creates an equal pressure area on both faces, ensuring push and pull forces match exactly at 3175 N when running at 0.7 MPa. This JIS-standard profile body is noticeably shorter than an equivalent ISO 15552 cylinder, saving machine footprint while retaining a hard-anodized aluminum barrel.
With a G3/8 port and a 25 mm piston rod, it handles substantial loads safely. The 2268 N output translates to a safe working load of about 1361 N, which is enough to vertically lift roughly 116 kg with a 2:1 safety margin. Note that this specific SKU lacks a magnet, so it cannot accept CMSE or DMSE sensors; you would need the -S variant for position detection.

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

Where the Airtac JSID Double Rod Cylinder JSID80X70 Is Used
Dual-End Transfer Pusher
Pushes a product from one conveyor lane to another using the rear rod, while the front rod simultaneously retracts a diverter gate, keeping motion synchronized.
Anti-Rotation Stamping Head
Uses the twin-rod symmetry to resist twist during a 2268 N stamping operation, maintaining precise tool alignment without needing external linear bearings.
Symmetric Lift Platform
Drives a small lifting cart from both ends simultaneously, ensuring the platform raises and lowers evenly under a 116 kg vertical load without binding.
Is the Airtac JSID Double Rod Cylinder JSID80X70 the Right Cylinder?
When sizing this 80 mm bore unit, stepping down to a 63 mm cylinder drops the equal-both-ways force to 1402 N at 0.5 MPa, while moving up to a 100 mm bore increases it to 3574 N. Choose this double-rod architecture when your mechanism demands anti-rotation stability, needs to drive twin tooling from opposite ends, or requires a symmetric load path to prevent side-loading. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because the 70 mm stroke is relatively short, external guide rails are less critical here than on longer strokes, but always support side loads. Remember that without live air, the cylinder drifts; use an external rod lock or pilot-operated check valve for secure load holding.
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 JSID80X70 FAQ
The force is equal in both directions because of the double-rod design. It provides 2268 N at 0.5 MPa and 3175 N at 0.7 MPa, with a theoretical maximum of 463 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, and it uses a G3/8 port.
No, this specific SKU does not include a magnet. To use CMSE or DMSE electronic sensors, you must purchase the -S variant of this double-rod cylinder. Without the magnet, you will need external mechanical or optical limit switches.
