Airtac JSID Double Rod Cylinder JSID40X500
The AirTAC JSID Double Rod Cylinder JSID40X500 is a genuine double acting, double rod JIS-standard air cylinder with a Ø40mm bore and 500mm 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 JSID40X500
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. The symmetric layout provides an anti-twist load path and allows you to drive twin tooling or mount a sensor cam at the back. Because the hard-anodized aluminum profile barrel omits external retaining rods, the JIS-standard body is noticeably shorter than an equivalent ISO 15552 cylinder of the same bore. It breathes through a G1/4 port and runs at 30-800 mm/s.
This non-magnetic SKU cannot accept a position switch; you would need the -S variant to use CMSE or DMSE sensors. Note that the adjustable 20.5 mm air cushions only decelerate the piston near the end of travel. They do not function as a brake, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended load.

Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |

Where the Airtac JSID Double Rod Cylinder JSID40X500 Is Used
Dual-End Transfer Pusher
Drives a transfer finger on the front rod while the rear rod simultaneously trips a mechanical limit valve, keeping both motions perfectly synchronized on a packaging line.
Balanced Lift Station
Raises and lowers a 27 kg fixture with equal push and pull force, using the symmetric rod layout to prevent binding during vertical actuation.
Anti-Rotation Index Unit
Moves a gripper carriage along a 500 mm stroke where the twin rods resist torsional twist, maintaining precise alignment without external linear bearings.
Is the Airtac JSID Double Rod Cylinder JSID40X500 the Right Cylinder?
Sizing a double-rod actuator means balancing the equal bidirectional force against your guidance needs. This 40 mm bore generates 528 N each way at 0.5 MPa. If your application is lighter, the 32 mm bore offers 345 N; for heavier drives, the 50 mm bore provides 825 N. Choose this twin-rod architecture when you need anti-rotation stability, symmetric load distribution, or a rear-end output for a cam. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this model has a 500 mm stroke, you must support the load with external linear guides to prevent rod bending and premature seal wear. This plain version lacks a magnet, so it cannot host reed or solid-state 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 JSID40X500 FAQ
The 40 mm bore produces equal force in both directions because the rod passes through both covers. It outputs 528 N at 0.5 MPa and 739 N at 0.7 MPa, with a theoretical maximum of 108 kgf at 1.0 MPa. It features a 16 mm rod, M14x1.5 rod thread, G1/4 port, and 20.5 mm adjustable cushions at both ends.
No, this specific SKU does not include a piston magnet and cannot accept a magnetic switch. You must specify the -S version of the cylinder to use CMSE or DMSE position sensors. Additionally, the air cushions only decelerate the piston and will not hold a load on air loss; use an external rod lock for suspended loads.
