Airtac JSID Double Rod Cylinder JSID80X650S
The AirTAC Airtac JSID Double Rod Cylinder JSID80X650S is a genuine double acting, double rod JIS-standard air cylinder with a Ø80mm bore and 650mm 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 JSID80X650S
Delivering 2268 N of thrust in both directions at 0.5 MPa, this 80 mm bore double-rod actuator uses a symmetric piston to completely eliminate push-pull force differential. The twin rods exiting both covers provide excellent anti-rotation guidance and let you mount a sensor cam or secondary tool on the back end. Its hard-anodized extruded aluminum profile is significantly shorter than a same-bore ISO 15552 unit, saving valuable machine space.
Equipped with a -S piston magnet for CMSE/DMSE switches, it handles your 650 mm stroke at speeds of 30-800 mm/s through G3/8 ports. The adjustable 29 mm air cushions at each end tame heavy end-of-stroke impacts. Based on the 0.5 MPa output, you get a safe working load of roughly 1361 N, which translates to lifting about 116 kg 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 JSID80X650S Is Used
Dual-Station Transfer
Uses both rod ends to push and pull a workpiece between two machining stations simultaneously, keeping the transfer path perfectly symmetric.
Balanced Press Head
Drives a heavy stamping or pressing fixture with equal 2268 N force on the downstroke and upstroke, relying on the twin rods for anti-rotation stability.
Cam-Driven Gating
Operates a diverter gate where the rear rod end carries a sensor cam, triggering CMSE/DMSE switches for precise mid-stroke position feedback.
Is the Airtac JSID Double Rod Cylinder JSID80X650S the Right Cylinder?
Sizing an 80 mm bore means balancing adjacent options: stepping down to a 63 mm bore yields 1402 N each way at 0.5 MPa, while moving up to a 100 mm bore provides 3574 N. Choose this double-rod architecture when your mechanism demands strict anti-twist alignment, symmetric load distribution, or needs to drive twin tooling simultaneously. Mounting hardware includes Basic, FA, LB, TC, TCM1, and TCM2 brackets. The included -S magnet allows direct side-groove installation of CMSE/DMSE reed or electronic sensors. Because the 650 mm stroke is quite long, always support the load with an external guide to prevent 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 JSID80X650S FAQ
The 80 mm bore generates equal force both ways: 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 features a 25 mm rod, M22x1.5 rod thread, G3/8 ports, and 29 mm adjustable cushions at both ends.
No, a standard pneumatic cylinder drifts when air is removed or the valve is centered. The adjustable cushions only decelerate the piston near the stroke ends; they do not lock the load. For static holding on this 650 mm stroke, install an external rod lock or a pilot-operated check valve.
