Airtac JSID Double Rod Cylinder JSID80X125
The AirTAC JSID Double Rod Cylinder JSID80X125 is a genuine double acting, double rod JIS-standard air cylinder with a Ø80mm bore and 125mm 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 JSID80X125
Delivering 2268 N of thrust in both directions at 0.5 MPa, this 80 mm bore double-rod JIS profile cylinder uses a single piston with a rod exiting each end. The twin rods create a symmetric load path that resists torsion and provides non-rotating anti-twist guidance for rigid tooling. Because the hard-anodized extruded aluminum barrel omits external rods, the body is significantly shorter than a same-bore ISO 15552 unit. It features a G3/8 port and M22x1.5 rod threads.
With a 125 mm stroke and 29 mm adjustable air cushions at both ends, it handles dynamic loads smoothly. Note this plain SKU lacks a magnet and cannot accept CMSE/DMSE sensors; you would need the -S variant for position detection.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |

Where the Airtac JSID Double Rod Cylinder JSID80X125 Is Used
Twin-Spindle Lifting
Drives two parallel workheads from opposite rod ends with equal 2268 N force, keeping heavy jigs balanced and preventing torsional twist during vertical lifts.
Symmetric Transfer Gate
Uses the dual rods to push and pull a transfer diverter from both sides simultaneously, ensuring the mechanism stays square under high reversing loads.
Non-Rotating Press Fixture
Holds a rigid pressing tool straight via the two rods, eliminating rotation without external linear guides while fitting into a compact JIS machinery footprint.
Is the Airtac JSID Double Rod Cylinder JSID80X125 the Right Cylinder?
When sizing this 80 mm bore, 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. The 80 mm strikes a middle ground with 2268 N both ways, making it ideal when you need substantial equal force for twin tooling setups, back-end sensor cam actuation, or symmetric load handling. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. For this 125 mm stroke, keep the load guided externally to prevent side-load wear on the 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 JSID80X125 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. It runs on G3/8 ports, uses an M22x1.5 rod thread, operates at 30-800 mm/s, and has 29 mm adjustable cushions at each end.
No, a plain double-rod cylinder drifts when air is lost or the valve is centered, as the cushions only decelerate near stroke end and do not lock the piston. For vertical load holding, you must add an external rod lock or a pilot-operated check valve.
