Airtac JSID Double Rod Cylinder JSID63X850STC
The AirTAC Airtac JSID Double Rod Cylinder JSID63X850STC is a genuine double acting, double rod JIS-standard air cylinder with a Ø63mm bore and 850mm 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 JSID63X850STC
Delivering 1402 N of thrust in both directions at 0.5 MPa, this double-rod JIS profile cylinder uses a single piston with a rod exiting each cover to ensure perfectly symmetric load paths. The extruded hard-anodized aluminum barrel keeps the overall body shorter than an ISO 15552 cylinder of the same 63 mm bore, while the G3/8 ports supply air to both chambers.
Because the piston sees the rod-side area on both faces, push and pull forces remain identical, which prevents twisting on long strokes. This specific configuration yields a safe working load of about 841 N, making it suitable for vertically lifting roughly 71 kg with a 2:1 safety margin. The built-in magnet allows CMSE/DMSE sensors to drop directly into the side grooves for precise end-position detection.

Where the Airtac JSID Double Rod Cylinder JSID63X850STC Is Used
Dual-End Transfer Pushers
Drives a transfer finger from the front rod while the rear rod simultaneously retracts a return cam, keeping conveyor pacing synchronized.
Symmetric Lift Platforms
Lifts roughly 71 kg of vertical load using the equal-both-ways force, ensuring the platform travels smoothly without inducing piston rotation.
Twin-Spindle Actuation
Mounts two small grippers on opposite rod ends to load and unload parts from two parallel machining stations in one stroke.
Is the Airtac JSID Double Rod Cylinder JSID63X850STC the Right Cylinder?
Sizing this actuator requires comparing adjacent bores: stepping down to a 50 mm bore provides 825 N each way, whereas moving up to an 80 mm bore yields 2268 N. The 63 mm bore hits a balanced 1402 N at 0.5 MPa, making it the right call when you need twin tooling driven from one piston or back-end sensor cam tracking. Mounting relies on the included TC clevis accessory alongside basic, FA, LB, TCM1, and TCM2 options. Since the stroke extends to 850 mm, you must support the load with external guides to prevent rod bending and manage side loads.
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 JSID63X850STC FAQ
This 63 mm bore cylinder features G3/8 ports and generates 1402 N of force at 0.5 MPa and 1962 N at 0.7 MPa. Because it is a double-rod design, this force is identical in both directions, with a theoretical maximum of 286 kgf at 1.0 MPa.
The S suffix indicates a built-in piston magnet for mounting CMSE or DMSE reed and electronic sensors in the barrel grooves. A plain cylinder cannot hold a load on air loss because the cushions only decelerate at stroke end; you must add an external rod lock or pilot-operated check valve for secure load holding.
