Airtac JSID Double Rod Cylinder JSID40X50S
The AirTAC JSID Double Rod Cylinder JSID40X50S is a genuine double acting, double rod JIS-standard air cylinder with a Ø40mm bore and 50mm 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 JSID40X50S
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 G1/4 port feeds the chamber, and because both faces share the identical rod-side area, push and pull forces remain equal at 739 N when running at 0.7 MPa. This JIS profile build is notably shorter than an equivalent ISO 15552 cylinder, using a hard-anodized aluminum extrusion instead of external steel bars.
The integrated -S magnet allows CMSE or DMSE sensors to drop directly into the side grooves for precise end-of-stroke detection. Adjustable 20.5 mm air cushions decelerate the piston smoothly at both ends, though a plain pneumatic 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 JSID40X50S Is Used
Dual-Tool Transfer
Drives two opposing pickers simultaneously from opposite rod ends, keeping cycle times synchronized without adding a second actuator.
Anti-Rotation Gauge
Holds a measuring head steady across a short 50 mm stroke, using the twin rods to resist torsional twist during part inspection.
Is the Airtac JSID Double Rod Cylinder JSID40X50S the Right Cylinder?
Stepping down, the 32 mm bore offers 345 N each way, while the larger 50 mm bore provides 825 N, making this 40 mm option the middle ground for moderate thrust. Choose the double-rod configuration when your mechanism requires anti-rotation stability, needs to drive two tools simultaneously from one actuator, or benefits from a symmetric load path. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The -S suffix confirms the piston magnet is present for switch sensing. For this 50 mm stroke, side loads are minimal, but any application exceeding 300 mm of travel should incorporate an external guide to prevent rod 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 JSID40X50S FAQ
The force is equal in both directions because of the double-rod design. It generates 528 N at 0.5 MPa and 739 N at 0.7 MPa, with a theoretical maximum of 108 kgf at 1.0 MPa. The air port is G1/4 and the rod-end thread is M14x1.5.
No, a standard pneumatic cylinder will drift and drop the load if air pressure is lost or the valve is centered. The adjustable 20.5 mm air cushions only decelerate the piston near the stroke ends and do not act as a brake. You must use an external rod lock or a pilot-operated check valve to hold a suspended load safely.
