Airtac JSID Double Rod Cylinder JSID50X800S
The AirTAC Airtac JSID Double Rod Cylinder JSID50X800S is a genuine double acting, double rod JIS-standard air cylinder with a Ø50mm bore and 800mm 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 JSID50X800S
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 end to ensure perfectly symmetric load paths. The hard-anodized aluminum extruded barrel keeps the overall body more compact and shorter than a same-bore ISO 15552 unit, while the G1/4 port manages the air supply. Because the effective area is identical on both faces, push and pull forces remain exactly equal.
With an 825 N output at 0.5 MPa, it handles a safe working load of about 495 N, which translates to lifting roughly 42 kg vertically with a 2:1 safety margin. The -S suffix indicates a built-in piston magnet for CMSE/DMSE switches that drop directly into the side sensor grooves. Note that the adjustable 20.5 mm cushions only decelerate the piston near the end of travel; a plain cylinder cannot hold a load on air loss, so fit an external rod lock or pilot-operated check valve if you need suspended load security.

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

Where the Airtac JSID Double Rod Cylinder JSID50X800S Is Used
Dual-End Transfer Pusher
Pushes parts from one conveyor lane to another using the front rod, while the rear rod simultaneously retracts a diverter gate for perfectly synchronized material handling.
Balanced Vertical Lift
Raises and lowers a 42 kg platen with equal force both ways, using the symmetric double-rod structure to prevent platform twisting during the 800 mm travel.
Twin-Spindle Tool Drive
Drives two opposing machining heads from a single central actuator, maintaining parallelism and saving axial space compared to using two separate cylinders.
Is the Airtac JSID Double Rod Cylinder JSID50X800S the Right Cylinder?
Sizing this 50 mm bore against its neighbors shows a clear step up from the 40 mm option (528 N each way) and a drop down from the 63 mm version (1402 N each way). Choose the double-rod layout when your mechanism demands anti-rotation stability, needs to drive two tools simultaneously from one actuator, or requires a sensor cam on the back end. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The -S magnet enables CMSE/DMSE switch integration. Because the stroke is 800 mm, you must support the mechanism with external guides to prevent rod bending and absorb side loads.
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 JSID50X800S FAQ
The force is equal in both directions because of the double-rod design. It provides 825 N at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical maximum of 168 kgf at 1.0 MPa. The air port size is G1/4.
No, a plain cylinder drifts on air loss. The adjustable air cushions only decelerate the piston near the stroke ends and do not act as a brake. For vertical load holding, you must install an external rod lock or a pilot-operated check valve.
