Airtac JSID Double Rod Cylinder JSID40X125S
The AirTAC JSID Double Rod Cylinder JSID40X125S is a genuine double acting, double rod JIS-standard air cylinder with a Ø40mm bore and 125mm 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 JSID40X125S
Delivering 528 N of thrust in both directions at 0.5 MPa, the AirTAC JSID40X125S uses a twin-rod layout where a single piston drives a shaft out of each end. This symmetric push and pull makes the unit ideal for non-rotating anti-twist guidance or carrying a sensor cam on the back side. The hard-anodized aluminum profile barrel keeps the body more compact and shorter than a same-bore ISO 15552 unit, while the G1/4 port manages the air supply.
Because the rod occupies both faces, the effective area stays identical each way, yielding 739 N at 0.7 MPa. The -S suffix means a built-in magnet is present for direct CMSE or DMSE switches along the side grooves.

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 JSID40X125S Is Used
Twin-Tool Transfer
Drives a part gripper on the front rod while the rear shaft simultaneously pushes an empty nest into position, keeping cycle time low.
Symmetric Lift Station
Balances a 27 kg vertical lift payload evenly across both rod ends, preventing chassis twist during upward and downward strokes.
Cam-Driven Sensing
Uses the extended back rod as a mechanical cam to trip external limit switches, while the internal -S magnet triggers CMSE sensors for redundant tracking.
Is the Airtac JSID Double Rod Cylinder JSID40X125S the Right Cylinder?
When sizing this family, the neighboring 32 mm bore yields 345 N each way at 0.5 MPa, whereas stepping up to a 50 mm bore provides 825 N. Choose this 40 mm double-rod version when your mechanism needs anti-rotation stability, twin tooling on opposite ends, or a symmetric load path. Mounting options cover Basic, FA, LB, TC, TCM1, and TCM2 brackets. For this 125 mm stroke, ensure external guide rails carry any lateral side-load to prevent binding. The -S magnet enables position detection, but remember a plain cylinder drifts on air loss; add an external rod lock or pilot-operated check valve for strict 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 JSID40X125S FAQ
Force is equal in both directions because the rod exits both ends. It generates 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 air port size is G1/4.
The -S suffix indicates a piston magnet for direct CMSE or DMSE reed and electronic switches. For load holding, note that the adjustable air cushion only decelerates near stroke end; on air loss the piston drifts, so you must fit an external rod lock or pilot-operated check valve to hold a suspended weight.
