Airtac JSID Double Rod Cylinder JSID40X800S
The AirTAC JSID Double Rod Cylinder JSID40X800S is a genuine double acting, double rod JIS-standard air cylinder with a Ø40mm 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 JSID40X800S
Delivering 528 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. The symmetric layout prevents rotation and provides a stable load path, while the hard-anodized aluminum extruded barrel keeps the total body shorter than a same-bore ISO 15552 unit. It feeds via a G1/4 port and carries an M14x1.5 rod thread.
With the built-in magnet, the -S variant accepts CMSE or DMSE sensors directly in the side grooves for end-of-stroke detection. Adjustable 20.5 mm air cushions at both ends absorb kinetic energy, though a plain cylinder drifts on air loss, so fit an external rod lock for holding.

Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |

Where the Airtac JSID Double Rod Cylinder JSID40X800S Is Used
Dual-End Transfer Pusher
Drives a transfer finger from one end while mounting a reject cam on the opposite rod for a synchronized sorting action.
Balanced Lift Station
Uses the symmetric double-rod geometry to lift a 27 kg vertical payload smoothly without inducing piston twist.
Sensor-Driven Gating
Uses the internal magnet with DMSE switches to confirm gate open and closed positions on a packaging line.
Is the Airtac JSID Double Rod Cylinder JSID40X800S the Right Cylinder?
Sizing spans both directions: drop to the 32 mm bore for 345 N, or step up to the 50 mm bore for 825 N, both equal each way. Choose this 40 mm double-rod unit when you need anti-rotation guidance, twin tooling driven from both ends, or a rear sensor cam. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. The -S magnet enables CMSE/DMSE position sensing. Because the stroke is 800 mm, always support the load with external guides to prevent rod bending and excessive side loading.
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 JSID40X800S FAQ
Force is equal in both directions at 528 N at 0.5 MPa and 739 N at 0.7 MPa, with a theoretical max of 108 kgf at 1.0 MPa. It operates at 0.15-1.0 MPa, runs 30-800 mm/s, and uses a G1/4 port.
The twin rods prevent rotation and allow driving two mechanisms or a sensor cam from the rear. It does not hold load on air loss; the cushions only decelerate, so use an external rod lock or pilot check valve for holding.
