Airtac JSID Double Rod Cylinder JSID63X120S
The AirTAC Airtac JSID Double Rod Cylinder JSID63X120S is a genuine double acting, double rod JIS-standard air cylinder with a Ø63mm bore and 120mm 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 JSID63X120S
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 ensure perfectly symmetric output. The twin rods prevent rotation under offset loads and allow you to mount a sensor cam or secondary tool on the back end. Built to JIS standards with an extruded hard-anodized aluminum profile barrel, the body is notably shorter and more compact than a same-bore ISO 15552 cylinder. It uses a G3/8 port and M18x1.5 rod thread.
The -S suffix indicates a built-in piston magnet for drop-in CMSE or DMSE switches. With a 0.5 MPa input, you get a safe working load of roughly 841 N, which translates to lifting about 71 kg vertically with a 2:1 safety margin. Adjustable 29 mm air cushions at both ends absorb impact, though a plain pneumatic cylinder cannot hold a load without live air—use an external rod lock or pilot-operated check valve for dead-load security.

Theoretical Output Force (Ø63mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |
| Max (@1.0 MPa) | 318 kgf | |
Double-rod: the rod passes through both covers, so output force is equal in both directions.

Where the Airtac JSID Double Rod Cylinder JSID63X120S Is Used
Twin-Tool Transfer
Drives two opposing pick-and-place grippers simultaneously, utilizing the equal push and pull force to maintain perfectly balanced part transfer without twist.
Anti-Rotation Press
Applies 1402 N of clamping force through a guided fixture, relying on the dual rods to prevent platen rotation during high-precision assembly operations.
Symmetric Cutting Station
Mounts a cutting blade on the front rod and a depth sensor cam on the rear rod, ensuring the stroke length is measured directly from the opposite end.
Is the Airtac JSID Double Rod Cylinder JSID63X120S the Right Cylinder?
Size both ways against your payload: the smaller 50 mm bore yields 825 N at 0.5 MPa, while the larger 80 mm bore provides 2268 N. Choose this 63 mm model when you need 1402 N each way with anti-rotation guidance or twin tooling stations. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. The -S variant supports CMSE/DMSE sensors; a no-S SKU cannot take a switch. For any stroke at or above 300 mm, add external guide rails to prevent side-load sagging.
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 JSID63X120S FAQ
Because it is a double-rod cylinder, force is equal both ways using the rod-side area. 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 air port is G3/8.
No. The adjustable 29 mm cushions only decelerate the piston near the stroke ends; they do not lock the load. To prevent drift on air loss or valve centering, you must install an external rod lock or a pilot-operated check valve.
