Airtac JSID Double Rod Cylinder JSID80X50
The AirTAC Airtac JSID Double Rod Cylinder JSID80X50 is a genuine double acting, double rod JIS-standard air cylinder with a Ø80mm bore and 50mm 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 JSID80X50
Delivering 2268 N of thrust in both directions at 0.5 MPa, this 80 mm bore double-rod actuator uses a symmetric piston design to ensure push and pull forces remain exactly equal. The rod exits both ends, which provides a non-rotating anti-twist load path and allows you to drive twin tooling or mount a rear sensor cam simultaneously. Built to JIS standards with an extruded hard-anodized aluminum profile barrel, it is noticeably shorter and more compact than a same-bore ISO 15552 cylinder. It features a G3/8 port, a 25 mm piston rod, and adjustable air cushions at both ends.
With a safe working load of roughly 1361 N, this actuator is good for about 116 kg lifted vertically with a 2:1 safety margin. Operating at speeds of 30-800 mm/s, it handles a 50 mm stroke effortlessly. Note that this specific SKU lacks a magnet and cannot take a CMSE or DMSE sensor; you would need the -S variant for position detection. Furthermore, a plain cylinder does not hold load on air loss—the cushions only decelerate near stroke end, so use an external rod lock or pilot-operated check valve for suspended loads.

Where the Airtac JSID Double Rod Cylinder JSID80X50 Is Used
Twin-Spindle Drilling
Drives two opposing machining heads simultaneously using the rods exiting both covers, keeping feed pressure perfectly balanced at 2268 N each way.
Symmetric Transfer Pusher
Pushes a workpiece forward while moving an identical return fixture backward, utilizing the equal both-ways force to maintain a stable, non-rotating load path.
Vertical Lift Gate
Raises a 116 kg gate with a 2:1 safety margin, relying on the compact JIS profile to save axial space while an external check valve holds the load safely.
Is the Airtac JSID Double Rod Cylinder JSID80X50 the Right Cylinder?
When sizing this 80 mm bore, the adjacent 63 mm option provides 1402 N both ways at 0.5 MPa, while the larger 100 mm bore yields 3574 N. Choose this double-rod configuration when your application demands anti-rotation guidance, symmetric load distribution, or twin tooling driven from one piston. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this is a non-magnetized SKU, it cannot accept magnetic sensors; select the -S version if you require CMSE or DMSE switches. For any stroke length of 300 mm or greater, always incorporate external guide rails to support side loads and prevent binding.
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 JSID80X50 FAQ
The 80 mm bore provides equal force in both directions: 2268 N at 0.5 MPa and 3175 N at 0.7 MPa, with a theoretical max of 463 kgf at 1.0 MPa. It uses a G3/8 port, a 25 mm rod with an M22x1.5 thread, and 29 mm adjustable cushions at both ends.
No, this base SKU does not have a magnet and cannot accept a CMSE or DMSE sensor. You must specify the -S variant to enable magnetic position sensing along the profile barrel.
