Airtac JSID Double Rod Cylinder JSID40X350
The AirTAC JSID Double Rod Cylinder JSID40X350 is a genuine double acting, double rod JIS-standard air cylinder with a Ø40mm bore and 350mm 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 JSID40X350
Delivering 528 N of thrust in both directions at 0.5 MPa, this double-acting profile cylinder uses a twin-rod design on one piston for perfectly symmetric load paths. The rod exits both ends, which prevents rotation and allows you to drive two tools at once.
Built to JIS standards with an extruded hard-anodized aluminum barrel, the unit is noticeably shorter than an ISO 15552 cylinder of the same 40 mm bore. It features a G1/4 port, adjustable air cushions of 20.5 mm at each end, and a 350 mm stroke. Note this specific SKU lacks a magnet, so it cannot accept CMSE or DMSE sensors without upgrading to the -S variant.

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

Where the Airtac JSID Double Rod Cylinder JSID40X350 Is Used
Twin-Tool Synchronization
Drives two opposing forming heads simultaneously from a single piston, ensuring perfectly matched contact pressure on both sides of a workpiece.
Anti-Rotation Guiding
The dual rods prevent piston twist during 350 mm extension, maintaining precise angular alignment for fine cutting or marking tasks.
Symmetric Diverting
Uses the rear rod end to push a diverter gate while the front rod simultaneously retracts a locking pin, keeping both actions mechanically locked in phase.
Is the Airtac JSID Double Rod Cylinder JSID40X350 the Right Cylinder?
This 40 mm bore provides 528 N equal force both ways, sitting neatly between the 32 mm bore at 345 N and the 50 mm bore at 825 N. A twin-rod configuration is the right call when you need anti-rotation guidance, symmetric load distribution, or a rear rod end to act as a sensor cam. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Because the stroke is 350 mm, add external guides to prevent rod bending under side loads. Also, remember this plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve to hold a load securely.
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 JSID40X350 FAQ
Because the rod passes through both covers, force is equal in both directions. It provides 528 N at 0.5 MPa and 739 N at 0.7 MPa, with a theoretical maximum of 108 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, and the air cushion only decelerates the piston near stroke end rather than holding the load.
No, this specific SKU does not have a magnet and cannot accept CMSE or DMSE switches. You must select the -S variant to enable position sensing. The twin-rod design still offers excellent non-rotating anti-twist guidance and a shorter JIS profile than a comparable ISO 15552 unit.
