Airtac JSID Double Rod Cylinder JSID40X300
The AirTAC JSID Double Rod Cylinder JSID40X300 is a genuine double acting, double rod JIS-standard air cylinder with a Ø40mm bore and 300mm 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 JSID40X300
Delivering 528 N of thrust in both directions at 0.5 MPa, this 40 mm bore double-rod actuator uses a single piston with a rod exiting each cover. Because both faces share the identical rod-side area, push and pull forces remain perfectly equal. This symmetric load path prevents twisting and is ideal for driving twin tooling stations simultaneously. The extruded hard-anodized aluminum profile barrel keeps the unit shorter and more compact than an equivalent ISO 15552 cylinder, while the G1/4 port manages air flow efficiently.
With a 300 mm stroke, you gain substantial travel for cycling parts or transferring components between stations. Note that this specific SKU lacks a magnet, so it cannot accept CMSE or DMSE sensors without switching to the -S variant. Furthermore, the adjustable air cushions only decelerate the piston near the end caps; they do not hold the load, so use an external rod lock or pilot-operated check valve if you need to prevent drift on air loss.

Where the Airtac JSID Double Rod Cylinder JSID40X300 Is Used
Dual-Tool Transfer
Simultaneously pushes and pulls two separate tooling heads across a 300 mm span, using the equal force and anti-twist stability of the dual rods to keep movements perfectly synchronized.
Symmetric Diverting
Diverts products from the center of a belt line using both rod ends, ensuring the 528 N actuation force remains balanced and preventing binding during high-speed sorting.
Is the Airtac JSID Double Rod Cylinder JSID40X300 the Right Cylinder?
When sizing this actuator, stepping down to a 32 mm bore provides 345 N each way, while moving up to a 50 mm bore increases the equal-both-ways output to 825 N at 0.5 MPa. Choose this double-rod configuration when your mechanism demands anti-rotation stability, symmetric load distribution, or needs to drive a sensor cam from the back end. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because the stroke is 300 mm, always support the load with external guides to prevent rod bending and premature seal wear. Remember that this non-magnet model cannot host position sensors.
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 JSID40X300 FAQ
The force is equal in both directions due to the double-rod design. It generates 528 N at 0.5 MPa and 739 N at 0.7 MPa, with a theoretical maximum of 108 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, and the air port size is G1/4.
No, this specific SKU does not include a magnet. You must select the -S variant to use CMSE or DMSE magnetic switches. Additionally, the adjustable air cushions only decelerate the piston near the stroke ends and will not hold a load; install an external rod lock or pilot-operated check valve for load holding.
