Airtac JSID Double Rod Cylinder JSID50X80S
The AirTAC Airtac JSID Double Rod Cylinder JSID50X80S is a genuine double acting, double rod JIS-standard air cylinder with a Ø50mm bore and 80mm 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 JSID50X80S
Delivering 825 N of thrust in both directions at 0.5 MPa, this AirTAC double-rod profile cylinder uses a 50 mm bore and an 80 mm stroke. The twin-rod layout creates a symmetric load path that resists torsional twist, while the hard-anodized aluminum barrel keeps the total build shorter than a same-bore ISO 15552 unit. A rod exits each end, allowing you to drive twin tooling stations or mount a rear sensor cam simultaneously.
The integrated -S piston magnet supports drop-in CMSE or DMSE switches for position feedback. Using the 0.5 MPa figure, you get a safe working load of roughly 495 N, which translates to lifting about 42 kg vertically with a 2:1 safety margin. It feeds through a G1/4 port, runs at 30-800 mm/s, and relies on adjustable 20.5 mm air cushions at both ends to decelerate the payload smoothly.

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

Where the Airtac JSID Double Rod Cylinder JSID50X80S Is Used
Twin-Tool Transfer
Simultaneously pushes two workpieces from a central position using the rod extending from each cover, keeping cycle times halved.
Anti-Rotation Press
Uses the symmetric dual-rod structure to press bearings straight down without torsional deflection or binding under load.
Symmetric Divertor
Mounts a cam on the rear rod to trigger a DMSE sensor while the front rod diverts packages on a packaging line.
Is the Airtac JSID Double Rod Cylinder JSID50X80S the Right Cylinder?
Sizing this 50 mm bore against its neighbors shows a clear step in power: the 40 mm bore yields 528 N both ways at 0.5 MPa, while the 63 mm bore jumps to 1402 N. Choose the 50 mm when you need that specific 825 N equal-both-ways output to drive opposing mechanisms or prevent rotation without external guides. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this is an -S SKU, the side grooves are ready for CMSE/DMSE electronic or reed sensors. For any stroke at or above 300 mm, add external guide rails to handle side loads and protect the piston seals.
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 JSID50X80S FAQ
Because the rod passes through both covers, force is equal in both directions. It delivers 825 N at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical maximum of 168 kgf at 1.0 MPa. Operating pressure spans 0.15 to 1.0 MPa, and it feeds via a G1/4 port.
No, a plain double-rod cylinder drifts without live air, as the 20.5 mm adjustable cushions only decelerate the piston near the stroke ends rather than locking it. To hold a suspended load safely, install an external rod lock or a pilot-operated check valve.
