Airtac JSID Double Rod Cylinder JSID50X450
The AirTAC Airtac JSID Double Rod Cylinder JSID50X450 is a genuine double acting, double rod JIS-standard air cylinder with a Ø50mm bore and 450mm 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 JSID50X450
Delivering 825 N of thrust in both directions at 0.5 MPa, this 50 mm bore double-rod actuator uses a single piston with a rod exiting each cover to guarantee equal push and pull force. The G1/4 port feeds the chamber, and because the pressure area is identical on both faces, you get perfectly symmetric load handling. This makes it good for about 495 N of real work, roughly 42 kg lifted vertically with a 2:1 safety margin.
Built to JIS standards with an extruded hard-anodized aluminum profile barrel, the body is noticeably shorter and more compact than an ISO 15552 cylinder of the same bore. The twin rods resist torsion and provide anti-twist guidance, allowing you to drive two tools at once or mount a sensor cam on the back end. Note this specific SKU lacks a magnet and cannot take a switch; order the -S version for CMSE/DMSE sensing.

Where the Airtac JSID Double Rod Cylinder JSID50X450 Is Used
Twin-Tool Transfer
Drives two opposing pickers simultaneously, using the equal both-ways force to keep the transfer balanced and prevent torsion on the guide rails.
Symmetric Lift Station
Lifts roughly 42 kg of vertical load with a 2:1 margin, relying on the dual rods to maintain parallel motion without twisting during the lift cycle.
Dual-End Sorting
Pushes a diverter from either end of a lane, using the rear rod to trip a mechanical cam while the front rod moves the product.
Is the Airtac JSID Double Rod Cylinder JSID50X450 the Right Cylinder?
When sizing this 50 mm bore, stepping down to a 40 mm bore yields 528 N both ways at 0.5 MPa, while stepping up to a 63 mm bore provides 1402 N. The 50 mm hits a solid middle ground at 825 N. A double rod is the right call when your mechanism demands anti-rotation stability, symmetric load paths, or twin tooling. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the stroke is 450 mm, you must account for side-load and rod-bending forces—always use external guides to prevent premature seal wear. Remember that a plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve for load holding, as the adjustable 20.5 mm cushions only decelerate near stroke end.
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 JSID50X450 FAQ
Because it is a double-rod cylinder, force is equal in both directions using the pull-side area. It outputs 825 N at 0.5 MPa and 1154 N at 0.7 MPa each way, with a theoretical max of 168 kgf at 1.0 MPa. It features a 50 mm bore, 450 mm stroke, G1/4 port, M18x1.5 rod thread, and adjustable air cushions of 20.5 mm at both ends.
No, this specific SKU does not have a magnet and cannot take a magnetic switch. If you need position sensing, you must select the -S variant of this model, which adds a magnet for use with CMSE or DMSE sensors.
