Airtac JSID Double Rod Cylinder JSID40X40S
The AirTAC JSID Double Rod Cylinder JSID40X40S is a genuine double acting, double rod JIS-standard air cylinder with a Ø40mm bore and 40mm 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 JSID40X40S
Delivering 528 N of thrust in both directions at 0.5 MPa, the AirTAC JSID40X40S uses a twin-rod layout on one piston to guarantee identical push and pull output. The rod exits both covers, which creates a symmetric load path that resists torsional twist and provides anti-rotation guidance without external rails.
This 40 mm bore JIS profile unit is notably shorter than a comparable ISO 15552 cylinder of the same size. It features a hard-anodized aluminum barrel, a G1/4 port, and an integrated piston magnet for CMSE/DMSE switches.

Where the Airtac JSID Double Rod Cylinder JSID40X40S Is Used
Symmetric Transfer
Drives a parts shuttle from both ends simultaneously, ensuring the payload stays perfectly aligned during horizontal indexing without rotational drift.
Twin-Tool Actuation
Powers two opposing forming heads that meet in the center, using the equal 528 N output to deliver balanced clamping pressure on both sides.
Is the Airtac JSID Double Rod Cylinder JSID40X40S the Right Cylinder?
For lighter tasks, the 32 mm bore offers 345 N each way, while stepping up to the 50 mm bore yields 825 N in both directions. Choose this double-rod configuration when your mechanism requires anti-rotation stability, twin tooling driven from opposite ends, or a sensor cam at the back. Mounting options include FA, LB, TC, TCM1, and TCM2. The S suffix means a magnet is installed for CMSE/DMSE position sensing. For this 40 mm stroke, side loads are minimal, but any stroke over 300 mm demands external guide rails to 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 JSID40X40S FAQ
Because the rod passes through both covers, force is equal in both directions: 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 uses a G1/4 port, operates at 0.15-1.0 MPa, and runs at 30-800 mm/s.
No, a standard pneumatic cylinder drifts when air pressure is lost or the valve is centered. The adjustable 20.5 mm air cushions only decelerate the piston near the end of stroke. To hold a suspended load safely, you must add an external rod lock or a pilot-operated check valve.
