Airtac JSID Double Rod Cylinder JSID40X80
The AirTAC JSID Double Rod Cylinder JSID40X80 is a genuine double acting, double rod JIS-standard air cylinder with a Ø40mm bore and 80mm stroke, G1/4 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 JSID40X80
Delivering 528 N of thrust in both directions at 0.5 MPa, this 40 mm double-rod JIS profile cylinder uses a single piston with a rod exiting each cover. The twin rods create a symmetric load path that resists torsion, letting you drive two tools at once or mount a sensor cam on the back end. Its extruded hard-anodized aluminum barrel keeps the build more compact and shorter than a same-bore ISO 15552 unit.
This SKU has no magnet and cannot take a switch, so choose the -S version if you need CMSE/DMSE sensing. An adjustable 20.5 mm air cushion decelerates the stroke at each end, but remember it only slows the piston; use an external rod lock or pilot-operated check valve to hold a suspended load.

Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |

Where the Airtac JSID Double Rod Cylinder JSID40X80 Is Used
Twin-Tool Transfer
Drives two parallel pick-and-place grippers simultaneously with equal 528 N force, keeping synchronous timing without adding a second cylinder.
Symmetric Forming Press
Applies balanced clamping pressure from both rod ends to center a workpiece, utilizing the compact JIS profile to save vertical machine space.
Is the Airtac JSID Double Rod Cylinder JSID40X80 the Right Cylinder?
Size both ways against this 40 mm bore: stepping down to 32 mm gives 345 N each way at 0.5 MPa, while stepping up to 50 mm provides 825 N. Select a double-rod configuration when your machine needs anti-rotation guidance, symmetric load distribution, or back-end actuation. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. For any stroke at or over 300 mm, add an external guide rail to prevent side-load binding. This non-magnet model lacks sensing; specify the -S variant for CMSE/DMSE switches.
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 JSID40X80 FAQ
Because it is a double-rod cylinder, force is equal in both directions using the rod-side area. It outputs 528 N at 0.5 MPa and 739 N at 0.7 MPa each way, with a theoretical maximum of 108 kgf at 1.0 MPa. The bore is 40 mm, the port is G1/4, and the rod thread is M14x1.5.
The twin rods provide a symmetric load path that prevents piston rotation, allowing you to drive two tools or mount a rear sensor cam. Additionally, the extruded hard-anodized aluminum profile barrel makes it shorter and more compact than a same-bore ISO 15552 cylinder. Note that this non-S SKU lacks a magnet and cannot accept CMSE/DMSE sensors.
