Airtac JSID Double Rod Cylinder JSID63X25S
The AirTAC Airtac JSID Double Rod Cylinder JSID63X25S is a genuine double acting, double rod JIS-standard air cylinder with a Ø63mm bore and 25mm stroke, G3/8 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 JSID63X25S
Delivering 1402 N of thrust in both directions at 0.5 MPa, the AirTAC JSID63X25S uses a twin-rod layout to ensure perfectly symmetric push and pull forces. This JIS-standard profile cylinder features an extruded hard-anodized aluminum barrel, making it noticeably shorter and more compact than a same-bore ISO 15552 unit. The rod exits both ends on a single piston, which prevents rotation and provides a stable platform for mounting a sensor cam or driving two tools at once.
Fitted with a G3/8 port and a 25 mm stroke, this -S variant includes a built-in piston magnet for CMSE/DMSE switches that drop directly into the side grooves. Based on the 1402 N output, it handles a safe working load of about 841 N, which translates to lifting roughly 71 kg vertically with a 2:1 safety margin. Note that a plain cylinder drifts on air loss; the adjustable 29 mm cushions only decelerate near the ends, so use an external rod lock for held loads.

Theoretical Output Force (Ø63mm)
| Pressure | Force (both ways) | — |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |

Where the Airtac JSID Double Rod Cylinder JSID63X25S Is Used
Twin-Tool Synchronization
Drives two opposing forming heads simultaneously with equal 1402 N force, ensuring parts are crimped evenly from both sides without rotational drift.
Cam-Driven Gauging
Uses the rear rod extension to push a mechanical measuring cam, allowing a DMSE sensor to verify the exact 25 mm position while the front end handles the work.
Symmetric Lift Platform
Lifts a balanced 71 kg vertical payload using the equal pull and push areas, maintaining stable guidance without twisting during the transfer cycle.
Is the Airtac JSID Double Rod Cylinder JSID63X25S the Right Cylinder?
When sizing this double-acting unit, the 63 mm bore sits comfortably between the smaller 50 mm option (825 N both ways) and the larger 80 mm model (2268 N both ways). Choose the JSID63X25S when your mechanism demands anti-rotation guidance, twin tooling on opposite sides, or a symmetric load path. It supports Basic, FA, LB, TC, TCM1, and TCM2 mounts. The -S suffix means you can install CMSE/DMSE sensors for position feedback. Because the stroke is only 25 mm, side-load risks are minimal, but any application exceeding 300 mm of travel should incorporate an external guide to protect the piston 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 JSID63X25S FAQ
The G3/8 port feeds a 63 mm bore that generates 1402 N at 0.5 MPa and 1962 N at 0.7 MPa. Because it is a double-rod cylinder, this force is identical in both directions, with a theoretical maximum of 286 kgf at 1.0 MPa.
Having a rod exit both ends creates an equal pressure area for stable, anti-rotation movement and allows rear-end sensor mounting. The -S option provides a built-in magnet for CMSE/DMSE switches, giving you precise position feedback without adding external hardware.
