Airtac JSID Double Rod Cylinder JSID50X700S
The AirTAC Airtac JSID Double Rod Cylinder JSID50X700S is a genuine double acting, double rod JIS-standard air cylinder with a Ø50mm bore and 700mm 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 JSID50X700S
Delivering 825 N of thrust in both directions at 0.5 MPa, this double-rod JIS profile cylinder uses a single piston with a rod exiting each cover. The symmetric layout creates an equal pressure area on both faces, ensuring push and pull forces remain identical. This makes it good for about 495 N of real work, roughly 42 kg lifted vertically with a 2:1 margin.
The extruded hard-anodized aluminium barrel keeps the unit more compact and shorter than an ISO 15552 cylinder of the same bore. A G1/4 port supplies air, while the -S suffix denotes a built-in piston magnet for CMSE/DMSE switches. Because the 700 mm stroke is long, external guides are recommended to prevent rod bending under side loads.

Theoretical Output Force (Ø50mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 825 N | 825 N |
| 0.7 MPa | 1155 N | 1155 N |

Where the Airtac JSID Double Rod Cylinder JSID50X700S Is Used
Twin-Tool Transfer
Drives two synchronized gripping fingers from opposite rod ends to shuttle parts between machining stations without rotation.
Symmetric Edge Guide
Uses the equal both-ways force to extend a guiding jaw from either side, keeping web materials centered during feed.
Balanced Vertical Lift
Lifts roughly 42 kg of payload using the stable double-rod path to prevent twisting on a 700 mm downward travel.
Is the Airtac JSID Double Rod Cylinder JSID50X700S the Right Cylinder?
When sizing this 50 mm bore, the adjacent 40 mm version yields 528 N each way, whereas stepping up to the 63 mm bore provides 1402 N. Choose the double-rod configuration when your application demands anti-rotation stability, symmetric load paths, or twin tooling driven from both ends. Mounting options include FA, LB, TC, TCM1, and TCM2. The -S magnet allows drop-in CMSE/DMSE sensors. For the 700 mm stroke, always support the load with external guides to avoid rod bending and 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 JSID50X700S FAQ
Force is equal in both directions at 825 N at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical max of 168 kgf at 1.0 MPa. The air port is G1/4.
No, a plain cylinder drifts without live air, as the adjustable cushion only decelerates near stroke end. For a held load, install an external rod lock or pilot-operated check valve.
