Airtac JSID Double Rod Cylinder JSID63X65STC
The AirTAC Airtac JSID Double Rod Cylinder JSID63X65STC is a genuine double acting, double rod JIS-standard air cylinder with a Ø63mm bore and 65mm 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 JSID63X65STC
Delivering 1402 N of thrust in both directions at 0.5 MPa, this 63 mm bore double-rod actuator uses a single piston with a rod exiting each cover. The symmetric layout creates an equal pressure area on both faces, so push and pull forces match perfectly. Because the rod passes through both ends, it naturally resists torsional twist and provides a built-in cam surface for rear-position sensing.
Built to JIS standards with an extruded hard-anodized aluminum profile barrel, the unit is notably shorter and more compact than a same-bore ISO 15552 cylinder. It features a G3/8 port, M18x1.5 rod threads, and 29 mm adjustable air cushions at each end. Factoring a realistic 60 percent efficiency margin, you get about 841 N of safe working load, which translates to lifting roughly 71 kg vertically with a 2:1 safety factor. The TC trunnion mount supports pivoting loads, and the built-in magnet allows CMSE/DMSE switches to drop directly into the side sensor grooves.

Where the Airtac JSID Double Rod Cylinder JSID63X65STC Is Used
Twin-Tool Transfer
Drives two synchronized gripping fingers from opposite rod ends to shuttle parts horizontally between machining stations without rotational twist.
Balanced Lift Station
Raises and lowers a 71 kg workpiece platform with equal push and pull force, ensuring smooth vertical travel guided by external rails.
Dual-Cam Sensing
Uses the rear rod extension as a mechanical cam to trigger DMSE electronic switches, confirming full retraction while the front rod executes the primary task.
Is the Airtac JSID Double Rod Cylinder JSID63X65STC the Right Cylinder?
When sizing this double-rod unit, compare its 1402 N equal-both-ways force at 0.5 MPa against neighboring bores: the 50 mm bore yields 825 N each way, while the 80 mm bore provides 2268 N. Choose this 63 mm model when your application demands anti-rotation guidance, twin tooling driven from both rod ends, or a symmetric load path to prevent side-loading bias. The TC trunnion accessory is ideal for clevis-style pivoting, and the -S magnet option enables precise end-of-stroke detection with CMSE/DMSE sensors. For any stroke length exceeding 300 mm, always incorporate an external linear guide to support the rod and prevent binding. Remember that the adjustable cushions only decelerate the piston near the end caps; they do not hold a load. If you need to maintain vertical position during air loss, add an external rod lock or a pilot-operated check valve.
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 JSID63X65STC FAQ
Because the rod exits both ends, the push and pull forces are equal. It generates 1402 N at 0.5 MPa and 1962 N at 0.7 MPa, with a theoretical maximum of 286 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, and the cylinder is proofed to 1.5 MPa. It uses a G3/8 port.
No. The 29 mm adjustable air cushions only decelerate the piston near the end of the stroke; they do not function as a brake. If air pressure is lost or the valve is centered, the piston will drift. For vertical load holding, you must install an external rod lock or a pilot-operated check valve.
