Airtac JSID Double Rod Cylinder JSID63X250
The AirTAC Airtac JSID Double Rod Cylinder JSID63X250 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 JSID63X250
Delivering 1402 N of thrust in both directions at 0.5 MPa, this 63 mm bore double-rod actuator uses a single piston with a rod exiting each cover to guarantee symmetric, equal force. The hard-anodized extruded aluminum profile barrel keeps the overall body shorter than a same-bore ISO 15552 unit. It carries a G3/8 port, M18x1.5 rod threads, and 29 mm adjustable air cushions at each end.
Because the twin rods share the load across a symmetric path, the unit resists torsional twist and guides payloads smoothly without rotation. This makes it good for about 841 N of real work, roughly 71 kg lifted vertically with a 2:1 safety margin. Note that this specific SKU lacks a magnet, so it cannot accept CMSE or DMSE position sensors.

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 JSID63X250 Is Used
Twin-Tool Transfer
Drives two opposing grippers simultaneously from one piston, keeping cycle times synchronized without adding a second cylinder.
Anti-Rotation Lift
Lifts heavy machining fixtures vertically without twisting, using the dual rods to maintain strict parallel alignment.
Symmetric Divertor
Pushes pallets from a central axis using equal force both ways, ensuring stable diverting across the belt width.
Is the Airtac JSID Double Rod Cylinder JSID63X250 the Right Cylinder?
Size both ways: the 50 mm bore yields 825 N each way at 0.5 MPa, while the 80 mm bore steps up to 2268 N. Choose this 63 mm model when you need 1402 N of equal bidirectional force. A double rod is the right call for anti-rotation guidance, driving twin tooling stations, or maintaining a symmetric load path. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. For the 250 mm stroke, add an external guide to absorb side loads and prevent rod binding. To add position sensing, select the -S magnet variant instead.
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 JSID63X250 FAQ
Force is equal in both directions at 1402 N at 0.5 MPa and 1962 N at 0.7 MPa, with a theoretical max of 286 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, and the cylinder runs at speeds of 30-800 mm/s.
No, a plain cylinder drifts on air loss, as the adjustable cushions only decelerate near stroke end. For vertical load holding, install an external rod lock or a pilot-operated check valve. Also, this non-S SKU lacks a magnet and cannot take sensors.
