Airtac JSID Double Rod Cylinder JSID50X80
The AirTAC Airtac JSID Double Rod Cylinder JSID50X80 is a genuine double acting, double rod JIS-standard air cylinder with a Ø50mm bore and 80mm 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 JSID50X80
Delivering 825 N of thrust in both directions at 0.5 MPa, this 50 mm bore double-rod actuator uses a G1/4 port and an 80 mm stroke. Because a rod exits both ends on a shared piston, the pressure area stays identical each way, making push and pull forces perfectly equal. This symmetric load path resists torsional twist and lets you mount a sensor cam or drive a second tool from the back end. The extruded hard-anodized aluminium profile barrel keeps the unit more compact and noticeably shorter than an ISO 15552 cylinder of the same bore.
Built to JIS standards rather than ISO 15552, it carries adjustable 20.5 mm air cushions at each end to decelerate the load smoothly. At 0.5 MPa you get about 495 N of safe working load, which is enough to vertically lift roughly 42 kg with a 2:1 safety margin. Note that this specific SKU lacks a magnet, so it cannot take a CMSE or DMSE sensor switch. The cushion only decelerates the piston near the stroke ends, so fit an external rod lock or pilot-operated check valve if you need to hold a load on air loss.

Where the Airtac JSID Double Rod Cylinder JSID50X80 Is Used
Twin-Tool Transfer
Drives a pick-and-place gripper on the front rod while simultaneously actuating a part-release cam on the rear rod, keeping cycle times synchronized.
Symmetric Lift Station
Lifts roughly 42 kg of vertical load using the equal both-ways force, preventing the sagging or uneven drift common in single-rod setups.
Anti-Rotation Press
Uses the dual rods through both covers to resist torsional twist during a 495 N safe working load pressing task, ensuring the ram stays perfectly perpendicular.
Is the Airtac JSID Double Rod Cylinder JSID50X80 the Right Cylinder?
Sizing this 50 mm bore gives 825 N equal force both ways at 0.5 MPa. If you need less power, step down to the 40 mm bore for 528 N; if you need more, step up to the 63 mm bore for 1402 N. Choose the double-rod layout when your machine needs anti-rotation guidance, twin tooling driven from one piston, a symmetric load path, or a rear-end sensor cam. You can mount it using the FA, LB, TC, TCM1, or TCM2 brackets. Because this 80 mm stroke is under 300 mm, side-load stress on the guides is minimal, but you should still keep the load aligned with the rod axis. Add the -S suffix if your controller requires position feedback, as this non-S SKU cannot host a sensor.
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 JSID50X80 FAQ
The force is equal in both directions because of the double-rod design. It outputs 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 have a magnet and cannot take a CMSE or DMSE sensor. You must order the JSID50X80-S variant to enable magnetic position sensing.
