Airtac JSID Double Rod Cylinder JSID40X225S
The AirTAC JSID Double Rod Cylinder JSID40X225S is a genuine double acting, double rod JIS-standard air cylinder with a Ø40mm bore and 225mm 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 JSID40X225S
Delivering 528 N of thrust in both directions at 0.5 MPa, this double-acting JIS profile cylinder uses a twin-rod design where a single piston drives a shaft out both ends. Because the pressure area is identical on each face, push and pull forces remain perfectly equal at 739 N when running at 0.7 MPa. The hard-anodized aluminum extruded barrel keeps the unit shorter and more compact than a same-bore ISO 15552 cylinder, while the G1/4 port supplies air efficiently.
With a 225 mm stroke, this -S variant carries a built-in piston magnet for CMSE/DMSE switches that drop directly into the side grooves. Adjustable 20.5 mm air cushions at both ends decelerate the load smoothly, though a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need 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 JSID40X225S Is Used
Twin-Tool Transfer
Drives two opposing grippers simultaneously from a single piston, keeping pick-and-place timing perfectly synchronized without extra plumbing.
Anti-Rotation Edge Guide
Uses the dual shafts to prevent twist during web routing, holding a steady plane that a single-rod actuator cannot maintain.
Dual-Cam Sensing Station
Uses the protruding rear rod to trip a CMSE/DMSE switch, confirming full retraction while the front end performs the primary work.
Is the Airtac JSID Double Rod Cylinder JSID40X225S the Right Cylinder?
Sizing this 40 mm bore requires looking both ways: step down to a 32 mm bore for 345 N, or up to a 50 mm bore for 825 N of equal-both-ways force at 0.5 MPa. Choose the JSID40X225S when your mechanism demands anti-rotation guidance, twin tooling driven from opposite ends, or a symmetric load path with back-end sensor cam tracking. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The -S suffix ensures you have the magnet ready for CMSE/DMSE sensors. Because the stroke is 225 mm, ensure you provide an external guide to handle any side-load and prevent binding.
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 JSID40X225S FAQ
The force is equal in both directions because of the double-rod design: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and a theoretical max of 108 kgf at 1.0 MPa. The air port size is G1/4, and it features an M14x1.5 rod thread.
A rod exiting both ends creates a symmetric load path that resists torsion and provides anti-rotation guidance. It also allows you to drive two tools at once or use the rear rod as a sensor cam for CMSE/DMSE switches, which is why this -S model includes a built-in magnet.
