Airtac JSID Double Rod Cylinder JSID80X300S
The AirTAC Airtac JSID Double Rod Cylinder JSID80X300S is a genuine double acting, double rod JIS-standard air cylinder with a Ø80mm bore and 300mm 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 JSID80X300S
Delivering 2268 N of thrust in both directions at 0.5 MPa, this 80 mm bore double-rod actuator uses a single piston with a rod exiting each cover to guarantee equal push and pull force. The hard-anodized aluminum profile barrel keeps the overall body shorter than an equivalent ISO 15552 cylinder, and the G3/8 ports supply ample flow for a 30 to 800 mm/s speed range.
With a built-in magnet, the -S variant accepts CMSE or DMSE switches in the side grooves for end-of-stroke detection. The twin rods create a symmetric load path that resists torsional twist, making the unit good for about 1361 N of real work, roughly 116 kg lifted vertically with a 2:1 safety margin.

Theoretical Output Force (Ø80mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |

Where the Airtac JSID Double Rod Cylinder JSID80X300S Is Used
Inline Transfer Pusher
Drives a dual-sided pusher bar to shift heavy pallets laterally across a conveyor lane without twisting.
Twin-Spindle Lift
Lifts a machining fixture using both rod ends to keep the platen perfectly level under an offset load.
Vertical Gate Actuator
Raises and lowers a 100 kg material handling gate with matched force on the upward and downward strokes.
Is the Airtac JSID Double Rod Cylinder JSID80X300S the Right Cylinder?
Sizing both ways, stepping down to a 63 mm bore yields 1402 N each way at 0.5 MPa, while stepping up to a 100 mm bore provides 3574 N. Choose this 80 mm double-rod model when your mechanism needs anti-rotation guidance, twin tooling driven from both ends, or a symmetric load path with back-end sensor cam clearance. It supports Basic, FA, LB, TC, TCM1, and TCM2 mounts. Because the stroke is 300 mm, add external guide rails to prevent rod bending under side loads. The -S magnet enables CMSE/DMSE position sensing.
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 JSID80X300S FAQ
Because the rod passes through both covers, force is equal in both directions: 2268 N at 0.5 MPa and 3175 N at 0.7 MPa, with a theoretical max of 463 kgf at 1.0 MPa. The air port size is G3/8, the rod is 25 mm, and it has M22x1.5 rod threads.
No, a plain double-rod cylinder will drift and drop the load if air is lost or the valve is centered. The adjustable 29 mm air cushions only decelerate the piston near stroke end and act as a brake. For secure load holding, install an external rod lock or a pilot-operated check valve.
