Airtac JSI Series Standard Cylinder JSI63X260S
The AirTAC Airtac JSI Series Standard Cylinder JSI63X260S is a genuine double acting JIS-standard air cylinder with a Ø63mm bore and 260mm 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 JSI Series Standard Cylinder JSI63X260S
Delivering 1559 N of push force at 0.5 MPa, the AirTAC JSI63X260S is a double-acting JIS-standard profile cylinder built for tight machinery layouts. Its extruded hard-anodized aluminum barrel omits external rods entirely, making the unit noticeably shorter and more compact than an ISO 15552 cylinder of the same 63 mm bore. The bore dictates a G3/8 port and an M18x1.5 rod-end thread, while a heterogeneous two-way piston seal retains grease for extended, low-friction service life.
Because this SKU includes the -S magnet, CMSE or DMSE electronic switches drop directly into the side sensor grooves for precise position detection. For practical sizing, plan for around 935 N of real work at 0.5 MPa, which translates to lifting roughly 79 kg vertically with a 2:1 safety margin. The 260 mm stroke operates at speeds of 30-800 mm/s, and adjustable 29 mm air cushions at both ends decelerate the piston smoothly at stroke extremes.

Where the Airtac JSI Series Standard Cylinder JSI63X260S Is Used
Pallet Diverters
Handles the lateral shifting of workpiece pallets along a 63 mm conveyor belt, utilizing the 260 mm stroke to push components cleanly into secondary machining stations.
Carton Flap Folders
Folds top flaps on outbound packaging cartons in a logistics warehouse, where the 1559 N force easily overcomes board stiffness without crushing the contents.
Press Tool Ejection
Ejects lightweight aluminum castings from a precision_manufacturing press die, relying on the -S magnet and DMSE sensors to confirm part clearance before the mold closes.
Is the Airtac JSI Series Standard Cylinder JSI63X260S the Right Cylinder?
When sizing this 63 mm bore, stepping down to a JSI50 yields 982 N of push at 0.5 MPa, whereas moving up to a JSI80 provides 2513 N, giving you clear room to adjust if the 1559 N rating is too tight or overly generous. The integrated -S magnet pairs seamlessly with CMSE/DMSE sensors for end-of-stroke confirmation. Keep in mind that standard air cushions only decelerate the piston near the end caps; they do not function as a lock. If your process requires the load to stay put upon air loss or valve centering, fit an external rod lock or a pilot-operated check valve to prevent drift.
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 JSI Series Standard Cylinder JSI63X260S FAQ
This 63 mm bore cylinder features a G3/8 air port and an M18x1.5 rod thread. It generates 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push and 1962 N pull at 0.7 MPa, with a theoretical maximum force of 318 kgf at 1.0 MPa.
The extruded hard-anodized aluminum barrel removes the need for external rods, making the JSI series significantly shorter and more compact than an ISO 15552 cylinder of the same bore while maintaining robust double-acting performance.
