Airtac JSID Double Rod Cylinder JSID40X50
The AirTAC JSID Double Rod Cylinder JSID40X50 is a genuine double acting, double rod JIS-standard air cylinder with a Ø40mm bore and 50mm 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 JSID40X50
Delivering 528 N of thrust in both directions at 0.5 MPa, this 40 mm double-rod JIS profile cylinder uses a single piston with a 16 mm rod exiting both covers. Because the pressure area is identical on each face, push and pull forces remain perfectly equal. The extruded hard-anodized aluminum barrel keeps the build shorter and more compact than a same-bore ISO 15552 unit, while the G1/4 port manages airflow efficiently.
A rod out each end provides symmetric load paths and anti-twist guidance for twin tooling or rear sensor cams. Note that this specific SKU lacks a magnet, so it cannot accept CMSE or DMSE sensors without upgrading to the -S variant.

Where the Airtac JSID Double Rod Cylinder JSID40X50 Is Used
Twin Tool Transfer
Drive two opposing grippers simultaneously from both rod ends to pick and place parts from parallel conveyors without adding a second actuator.
Anti-Rotation Lift
Lift a 27 kg vertical payload using the symmetric double-rod geometry to prevent platform twist and maintain precise vertical alignment without external guides.
Symmetric Clamping
Apply 528 N of equal clamping force from both sides of a workpiece simultaneously, ensuring balanced holding during a machining or testing process.
Is the Airtac JSID Double Rod Cylinder JSID40X50 the Right Cylinder?
Size both ways against the 40 mm bore: drop to the 32 mm for 345 N, or step up to the 50 mm for 825 N, both at 0.5 MPa. Choose this double-rod layout when your mechanism demands anti-rotation stability, symmetric load distribution, or twin tooling driven from one piston. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Since the stroke is 50 mm, side-load guidance is minimal, but always support the rod end to maximize seal life.
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 JSID40X50 FAQ
Force is equal both ways at 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 16 mm rod, M14x1.5 rod thread, G1/4 port, 20.5 mm adjustable air cushions, and operates at 30-800 mm/s.
No, a plain cylinder drifts on air loss because the air cushion only decelerates near stroke end and acts as neither a lock nor a brake. For vertical load holding, you must install an external rod lock or a pilot-operated check valve.
