Airtac JSID Double Rod Cylinder JSID63X350
The AirTAC Airtac JSID Double Rod Cylinder JSID63X350 is a genuine double acting, double rod JIS-standard air cylinder with a Ø63mm bore and 350mm 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 JSID63X350
Delivering 1402 N of thrust in both directions at 0.5 MPa, this 63 mm bore double-rod actuator uses a G3/8 port and a 350 mm stroke. Its symmetric piston rod exits both covers, creating an identical effective area on each face so push and pull forces remain exactly equal. This layout naturally resists torsional twist and provides a stable, anti-rotation load path for guided tooling. Built as a JIS-standard extruded profile cylinder, it is noticeably shorter and more compact than a same-bore ISO 15552 unit.
With a 0.5 MPa input, the 1402 N output translates to a safe working load of about 841 N, which is roughly 71 kg lifted vertically with a 2:1 safety margin. The hard-anodized aluminum barrel incorporates adjustable 29 mm air cushions at both ends to decelerate the payload smoothly. Note that this specific SKU lacks a magnet and cannot accept position sensors; adding the -S variant enables CMSE or DMSE switches. Because the 350 mm stroke is fairly long, external load guides are recommended to prevent rod bending under side loads.

Where the Airtac JSID Double Rod Cylinder JSID63X350 Is Used
Twin-Spindle Drilling
Drives two opposing machining heads simultaneously using the rods protruding from both end covers, ensuring perfectly synchronized feed rates.
Symmetric Transfer Gate
Shifts a guided divert gate from either end with equal 1402 N force, maintaining a balanced load path that prevents binding during high-speed sorting.
Centered Lift Platform
Raises and lowers a 71 kg guided vertical fixture with equal push and pull thrust, relying on the dual rods to resist torsional twist.
Is the Airtac JSID Double Rod Cylinder JSID63X350 the Right Cylinder?
When sizing this double-rod family, the neighboring 50 mm bore provides 825 N each way at 0.5 MPa, while the larger 80 mm bore steps up to 2268 N. The 63 mm bore sits comfortably in the middle at 1402 N. A double-rod configuration is the right call when your mechanism demands anti-rotation stability, needs to drive two tools simultaneously from one piston, or requires a symmetric load path with a sensor cam at the back end. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this is a non-magnetized SKU, it cannot host reed or solid-state switches; select a JSID63X350-S model if you require CMSE/DMSE position sensing. For the 350 mm stroke, always pair the cylinder with an external linear guide to absorb side loads and prevent rod bending.
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 JSID63X350 FAQ
Because the rod passes through both covers, force is equal in both directions. It delivers 1402 N at 0.5 MPa and 1962 N at 0.7 MPa, with a theoretical maximum of 286 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, and the air port size is G3/8.
No, this plain SKU lacks a magnet and cannot accept CMSE or DMSE sensors; you need the -S variant for position detection. Furthermore, a standard cylinder does not hold load on air loss—the adjustable 29 mm cushions only decelerate near stroke end. For a suspended vertical load, install an external rod lock or pilot-operated check valve.
