Airtac JSID Double Rod Cylinder JSID40X800
The AirTAC JSID Double Rod Cylinder JSID40X800 is a genuine double acting, double rod JIS-standard air cylinder with a Ø40mm bore and 800mm 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 JSID40X800
Delivering 528 N of thrust in both directions at 0.5 MPa, this 40 mm bore double-rod actuator uses a single piston with a rod exiting each cover to ensure perfectly symmetric load paths. The twin rods resist torsional twist and provide non-rotating guidance, which is highly valuable for driving two synchronized mechanisms or mounting a rear sensor cam. Because both faces use the identical rod-side area, push and pull outputs match exactly at 739 N when running at 0.7 MPa.
Built to JIS standards with an extruded hard-anodized aluminum profile barrel, the body is notably shorter and more compact than an equivalent ISO 15552 cylinder of the same bore. It features a G1/4 port and adjustable air cushions of 20.5 mm at both ends to tame end-of-stroke impacts. Note this specific SKU lacks a magnet and cannot accept CMSE or DMSE sensors.

Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | 739 N |

Where the Airtac JSID Double Rod Cylinder JSID40X800 Is Used
Twin Tool Transfer
Drives two synchronized pickers from opposite rod ends to move parts across a conveyor belt without rotation.
Symmetric Stamping
Applies equal 528 N clamping force from both faces to hold thin metal sheets flat during a light stamping process.
Dual-End Sorting
Uses the rear rod extension to push a diverter cam while the front rod actuates a package gate in a packing line.
Is the Airtac JSID Double Rod Cylinder JSID40X800 the Right Cylinder?
When sizing this unit, look at the neighboring bores: the smaller 32 mm bore provides 345 N each way at 0.5 MPa, while the larger 50 mm bore yields 825 N. Choose the 40 mm bore when your application demands approximately 528 N of equal bidirectional force. A double-rod design is the right call when you need anti-rotation stability, symmetric load distribution, or twin tooling driven from one piston. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because this is an 800 mm stroke, you must support the load with external guides to prevent rod bending and excessive side loading. To add position sensing, select the -S magnet variant for CMSE or DMSE switches, as this base model cannot take a sensor.
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 JSID40X800 FAQ
Because the rod passes through both covers, force is equal in both directions. It generates 528 N each way at 0.5 MPa, 739 N each way at 0.7 MPa, and a theoretical maximum of 108 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, and it uses a G1/4 port.
No, a plain double-rod cylinder drifts without live air; the 20.5 mm adjustable cushion only decelerates near stroke end and does not lock the load. For holding, use an external rod lock or pilot-operated check valve. Additionally, this SKU has no magnet and cannot take a sensor; you must specify the -S version for CMSE or DMSE switches.
