Airtac JSID Double Rod Cylinder JSID50X500S
The AirTAC Airtac JSID Double Rod Cylinder JSID50X500S is a genuine double acting, double rod JIS-standard air cylinder with a Ø50mm bore and 500mm 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 JSID50X500S
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 both covers. The symmetric layout prevents rotation and provides a stable load path, while the extruded hard-anodized aluminum barrel keeps the total body shorter than a same-bore ISO 15552 unit. It features a G1/4 port and adjustable air cushions at both ends.
With its built-in piston magnet, the -S variant accepts CMSE/DMSE sensors in the side grooves for end-of-stroke detection. The 825 N output translates to a safe working load of about 495 N, which is roughly 42 kg lifted vertically with a 2:1 safety margin. Because the 500 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 |

Where the Airtac JSID Double Rod Cylinder JSID50X500S Is Used
Dual-Station Transfer
Uses both rod ends to push and pull a workpiece between two machining stations simultaneously, cutting cycle time in half.
Symmetric Lift Fixture
Lifts and lowers a 42 kg platen with equal force both ways, relying on the twin rods to prevent platform twist during vertical travel.
Cam-Actuated Sorting
Uses the rear rod extension as a mechanical cam to trigger an external proximity sensor, confirming full retraction without internal switches.
Is the Airtac JSID Double Rod Cylinder JSID50X500S the Right Cylinder?
This 50 mm bore sits between the 40 mm bore (528 N each way) and the 63 mm bore (1402 N each way), giving you a clear upgrade path if your payload changes. A double-rod design is the right call when you need anti-rotation stability, want to drive two tools from one cylinder, or require a sensor cam on the back end. Mounting options include FA, LB, TC, TCM1, and TCM2. The -S magnet enables CMSE/DMSE switch mounting. For this 500 mm stroke, always support the load with external linear 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 JSID50X500S FAQ
Because the rod passes through both covers, force is equal in both directions: 825 N at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical maximum of 168 kgf at 1.0 MPa. It uses a G1/4 port, has an M18x1.5 rod thread, and operates at speeds of 30-800 mm/s.
No, a plain cylinder will drift if air is lost or the valve is centered, as the adjustable air cushion only decelerates the piston near the stroke ends. To maintain a vertical load safely, you must add an external rod lock or a pilot-operated check valve.
