Airtac JSID Double Rod Cylinder JSID40X75
The AirTAC JSID Double Rod Cylinder JSID40X75 is a genuine double acting, double rod JIS-standard air cylinder with a Ø40mm bore and 75mm 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 JSID40X75
Delivering 528 N of thrust in both directions at 0.5 MPa, the AirTAC JSID40X75 uses a twin-rod layout to provide perfectly symmetrical push and pull force. Because the 16 mm rod passes through both covers, the effective pressure area remains identical each way, yielding 739 N at 0.7 MPa and a 108 kgf maximum. This JIS profile body is noticeably shorter than a same-bore ISO 15552 unit, built around a hard-anodized aluminium extrusion with a G1/4 port.
The twin rods resist torsional twist for non-rotating guidance, while the adjustable 20.5 mm air cushions at each end decelerate the 75 mm stroke smoothly. Note that this specific SKU lacks a magnet, so it cannot accept CMSE or DMSE sensors without switching to an -S variant.

Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | 739 N |

Where the Airtac JSID Double Rod Cylinder JSID40X75 Is Used
Twin-End Transfer
Drives a part pusher on the front rod while the rear extension cycles a diverter cam, keeping both actions perfectly synchronised.
Anti-Rotation Stamp
The dual rods prevent piston twist during a 75 mm down-stroke, holding a small stamping head rigid against the workpiece.
Symmetric Clamping
Applies 528 N of equal clamping force from both sides of a fixture, securing delicate components without skewing the load.
Is the Airtac JSID Double Rod Cylinder JSID40X75 the Right Cylinder?
This 40 mm bore sits between the JSID32 (345 N each way) and the JSID50 (825 N each way), making it a solid mid-range choice when the smaller bore lacks thrust. The double-rod architecture is ideal when you need anti-rotation stability, symmetric load distribution, or a rear rod extension to drive a secondary mechanism. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because this is a non-magnetized model, position sensing is not possible. For any stroke at or over 300 mm, always use an external guide to prevent side-load wear on the seals.
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 JSID40X75 FAQ
Force is equal in both directions at 528 N at 0.5 MPa and 739 N at 0.7 MPa, with a theoretical maximum of 108 kgf at 1.0 MPa. The air port size is G1/4.
No, a plain cylinder drifts on air loss and the 20.5 mm cushions only decelerate near stroke end, they do not lock the piston. For vertical load holding you must add an external rod lock or a pilot-operated check valve.
