Airtac JSID Double Rod Cylinder JSID63X250S
The AirTAC Airtac JSID Double Rod Cylinder JSID63X250S is a genuine double acting, double rod JIS-standard air cylinder with a Ø63mm bore and 250mm stroke, G3/8 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 JSID63X250S
Delivering 1402 N of thrust in both directions at 0.5 MPa, this 63 mm double-rod profile cylinder uses a single piston with a rod exiting each end. The symmetric layout provides a stable, anti-rotation load path while letting you drive twin tooling or mount a rear sensor cam. Because it follows a JIS standard, the hard-anodized aluminum extrusion is noticeably shorter than an equivalent ISO 15552 unit of the same bore.
The built-in -S piston magnet supports CMSE and DMSE reed or electronic switches that clip directly into the side grooves. With a practical working load of about 841 N, it can vertically lift roughly 71 kg with a 2:1 safety margin. Air connects via a G3/8 port, and adjustable 29 mm cushions decelerate the stroke smoothly at both ends.

Theoretical Output Force (Ø63mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |

Where the Airtac JSID Double Rod Cylinder JSID63X250S Is Used
Twin-Tool Transfer
Drives two parallel grippers simultaneously from opposite rod ends to transfer parts evenly between conveyor stations.
Anti-Rotation Edge Guide
Uses the dual-rod symmetry to prevent mechanical twist while positioning long web materials on a converting line.
Balanced Vertical Lift
Lifts and lowers a 71 kg platen with a 2:1 safety margin, relying on the equal push and pull forces for smooth descent.
Is the Airtac JSID Double Rod Cylinder JSID63X250S the Right Cylinder?
Sizing around this 63 mm bore means checking both neighbors: a 50 mm bore provides 825 N each way at 0.5 MPa, while an 80 mm bore steps up to 2268 N. Choose a double-rod configuration when your mechanism demands anti-rotation guidance, symmetric load distribution, or simultaneous actuation from both ends. This JSID model mounts via Basic, FA, LB, TC, TCM1, or TCM2 brackets. The -S variant includes the magnet for switch sensing. Because the stroke is 250 mm, ensure external guide rails carry any lateral side-load to prevent premature seal wear.
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 JSID63X250S FAQ
Force is equal in both directions because the rod passes through both covers. It outputs 1402 N at 0.5 MPa and 1962 N at 0.7 MPa, with a theoretical max of 286 kgf at 1.0 MPa. The bore is 63 mm, the port is G3/8, and speed ranges 30-800 mm/s.
No, the air cushion only decelerates near stroke end; a plain cylinder drifts on air loss. Use an external rod lock or pilot-operated check valve for load holding. The -S suffix means it has a piston magnet for CMSE/DMSE switches to drop into the barrel grooves.
