Airtac JSID Double Rod Cylinder JSID40X25
The AirTAC JSID Double Rod Cylinder JSID40X25 is a genuine double acting, double rod JIS-standard air cylinder with a Ø40mm bore and 25mm 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 JSID40X25
Delivering 528 N of equal force in both directions at 0.5 MPa, this 40 mm bore double-rod actuator uses a single piston with a rod exiting each cover. The symmetric layout creates an anti-twist load path that prevents rotation, letting you drive two tools simultaneously or mount a rear sensor cam.
Built to JIS standards with an extruded hard-anodized aluminum profile barrel, it is shorter and more compact than an ISO 15552 cylinder of the same bore. This specific SKU lacks a magnet and cannot take a sensor; add the -S variant for CMSE/DMSE switches. It features a G1/4 port, a 16 mm rod, M14x1.5 threads, and 20.5 mm adjustable air cushions. Note that the cushion only decelerates near stroke end, so use an external rod lock or pilot-operated check valve to hold a load.

Where the Airtac JSID Double Rod Cylinder JSID40X25 Is Used
Twin-Tool Transfer
Drives two opposing grippers simultaneously with its dual rods, ensuring perfectly synchronized part handoff between conveyor stations.
Symmetric Crimping
Applies 317 N of safe working force from both ends to crimp small electronic connectors evenly without lateral drift.
Is the Airtac JSID Double Rod Cylinder JSID40X25 the Right Cylinder?
Size both ways against the 40 mm bore, which delivers 528 N both ways at 0.5 MPa. Step down to the 32 mm bore for 345 N, or up to the 50 mm bore for 825 N if your application needs more thrust. Choose this double-rod layout when you need anti-rotation guidance, twin tooling, a symmetric load path, or back-end sensing. Mounting options include FA, LB, TC, TCM1, and TCM2. Without the -S magnet, this cylinder cannot accept position sensors. For any stroke over 300 mm, add external guide rails to handle side 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 JSID40X25 FAQ
The 40 mm bore provides equal force both ways: 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 features a G1/4 port, a 16 mm rod, M14x1.5 rod thread, and 20.5 mm adjustable cushions. Speed ranges 30-800 mm/s.
No to both. The air cushion only decelerates near stroke end; use an external rod lock or pilot-operated check valve to hold a load. Also, this specific SKU lacks a magnet and cannot take a switch; you need the -S variant for CMSE/DMSE sensors.
