Airtac JSID Double Rod Cylinder JSID50X75
The AirTAC Airtac JSID Double Rod Cylinder JSID50X75 is a genuine double acting, double rod JIS-standard air cylinder with a Ø50mm 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 JSID50X75
Delivering 825 N of thrust in both directions at 0.5 MPa, the AirTAC JSID50X75 uses a twin-rod layout to give identical push and pull power. A rod exits each end of the hard-anodized aluminum profile barrel, creating a symmetric load path that resists torsional twist. This JIS-standard unit is notably shorter than an equivalent ISO 15552 cylinder of the same bore.
The 50 mm bore carries a 20 mm piston rod and uses G1/4 ports. It yields a safe working load of roughly 495 N, which is enough to vertically lift about 42 kg with a 2:1 safety margin. This specific SKU lacks a magnet, so it cannot accept CMSE or DMSE sensors; choose the -S variant for position detection.

Theoretical Output Force (Ø50mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 825 N | 825 N |
| 0.7 MPa | 1155 N | 1155 N |
| Max (@1.0 MPa) | 200 kgf | |
Double-rod: the rod passes through both covers, so output force is equal in both directions.

Where the Airtac JSID Double Rod Cylinder JSID50X75 Is Used
Twin-Tool Shuttle
Drives two opposing pickers simultaneously from one piston, keeping cycle times balanced without adding a second actuator.
Symmetric Lift Station
Lifts roughly 42 kg of vertical payload evenly, using the equal force both ways to prevent sagging on the return drop.
Anti-Twist Clamp
Holds a workpiece flat against a fixture using the non-rotating twin-rod geometry to prevent angular deflection during clamping.
Is the Airtac JSID Double Rod Cylinder JSID50X75 the Right Cylinder?
Sizing this actuator requires comparing adjacent bores: the 40 mm version provides 528 N each way, while the 63 mm steps up to 1402 N. Choose the 50 mm bore when your application demands 825 N at 0.5 MPa. A twin-rod design is the right call when you need anti-rotation guidance, want to drive two tools at once, or require a sensor cam on the back end. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this 75 mm stroke is under 300 mm, side-load stress is minimal, but external guides are still recommended for any stroke at or above 300 mm.
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 JSID50X75 FAQ
Because the rod passes through both covers, force is equal in both directions. It outputs 825 N at 0.5 MPa and 1154 N at 0.7 MPa each way. The theoretical maximum is 168 kgf at 1.0 MPa. The cylinder uses a G1/4 port.
No. A plain double-rod cylinder drifts without live air, as the adjustable 20.5 mm cushions only decelerate the piston near stroke end rather than locking it. To hold a suspended load, install an external rod lock or a pilot-operated check valve.
