Airtac JSID Double Rod Cylinder JSID80X250S
The AirTAC Airtac JSID Double Rod Cylinder JSID80X250S is a genuine double acting, double rod JIS-standard air cylinder with a Ø80mm bore and 250mm 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 JSID80X250S
Delivering 2268 N of thrust in both directions at 0.5 MPa, this 80 mm double-rod JIS profile cylinder brings symmetric power to demanding jobs. The hard-anodized aluminum barrel keeps the build more compact than a same-bore ISO 15552 unit, while the twin rods exiting both ends prevent torsional twist and allow driving two mechanisms at once.
A built-in magnet equips the JSID80X250S for CMSE or DMSE position switches. With a G3/8 port and a safe working load around 1361 N, it is well suited for lifting roughly 116 kg vertically. The adjustable 29 mm cushions absorb kinetic energy at stroke ends, though external check valves are needed to hold loads securely.

Where the Airtac JSID Double Rod Cylinder JSID80X250S Is Used
Dual-Station Transfer
Simultaneously pushes a workpiece onto an outbound belt while pulling the next fixture into place, using the equal 2268 N force to keep both motions perfectly synchronized.
Anti-Rotation Press
Uses the twin opposing rods to guide a stamping head without rotational drift, ensuring precise alignment on metal components during a 250 mm pressing cycle.
Symmetric Lift Gate
Drives a heavy material handling gate from both ends simultaneously, splitting the 116 kg vertical lifting capacity across a balanced load path to prevent jamming.
Is the Airtac JSID Double Rod Cylinder JSID80X250S the Right Cylinder?
This 80 mm bore sits between the 63 mm option, which yields 1402 N each way at 0.5 MPa, and the 100 mm version, which provides 3574 N. Choose the double-rod layout when your application demands anti-rotation stability, mirrored tooling on opposite sides, or a symmetric load path. Mounting hardware includes Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this unit carries the S suffix, it accepts CMSE and DMSE sensors in its side grooves. For this 250 mm stroke, ensure external guide rails are used to absorb lateral loads and prevent binding.
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 JSID80X250S FAQ
Because the piston rod passes through both covers, force is equal in both directions. It generates 2268 N at 0.5 MPa and 3175 N at 0.7 MPa, with a theoretical maximum of 463 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, and the air port size is G3/8.
No, a standard double-rod cylinder will drift if air pressure is lost or the valve is centered. The adjustable 29 mm air cushions only decelerate the piston near the end of stroke and do not act as a brake. You must add an external rod lock or a pilot-operated check valve to hold a load securely.
