Airtac JSID Double Rod Cylinder JSID50X125
The AirTAC Airtac JSID Double Rod Cylinder JSID50X125 is a genuine double acting, double rod JIS-standard air cylinder with a Ø50mm bore and 125mm 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 JSID50X125
Delivering 825 N of thrust in both directions at 0.5 MPa, this AirTAC 50 mm bore double-rod cylinder uses a single piston with a rod exiting each cover to ensure perfectly symmetric load paths. The G1/4 port feeds the hard-anodized aluminum profile barrel, making the unit significantly shorter than a same-bore ISO 15552 cylinder while completely avoiding rotation twist.
With a 125 mm stroke, it yields a safe working load of about 495 N, which translates to lifting roughly 42 kg vertically with a 2:1 safety margin. Note that this specific SKU lacks a magnet, so it cannot accept CMSE or DMSE position sensors without upgrading to the -S variant. Furthermore, the adjustable 20.5 mm air cushions only decelerate the piston near the end caps; they do not hold the load, so fit an external rod lock or pilot-operated check valve if you need drift prevention.

Theoretical Output Force (Ø50mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 825 N | 825 N |
| 0.7 MPa | 1155 N | 1155 N |

Where the Airtac JSID Double Rod Cylinder JSID50X125 Is Used
Twin-Tool Synchronization
Drives two opposing forming tools simultaneously from both rod ends, ensuring perfectly matched contact pressure without requiring a separate mechanical linkage.
Anti-Rotation Web Guide
Holds a precision web or film guiding blade rigidly on both ends to prevent angular deflection during high-speed material tracking adjustments.
Symmetric Lift Platform
Balances a 42 kg vertical lifting platen equally across both rod sides, maintaining level elevation without inducing piston cocking or uneven seal wear.
Is the Airtac JSID Double Rod Cylinder JSID50X125 the Right Cylinder?
When sizing this double-acting unit, look both ways: stepping down to the 40 mm bore drops the equal-both-ways force to 528 N at 0.5 MPa, while moving up to the 63 mm bore increases it to 1402 N. Choose this 50 mm model when your application demands anti-rotation guidance, twin tooling driven from both rod ends, or a symmetric load setup. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this SKU has no -S suffix, it cannot host magnetic switches. For this 125 mm stroke, ensure external load guides are used to prevent excessive side-loading on the rod 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 JSID50X125 FAQ
Because the rod passes through both covers, force is equal in both directions: 825 N at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical max of 168 kgf at 1.0 MPa. The air port size is G1/4.
No, this specific SKU does not include a magnet and cannot accept CMSE or DMSE switches. You must order the -S variant of this double-rod profile cylinder to enable magnetic position sensing.
