Airtac JSI Series Standard Cylinder JSI63X280STC
The AirTAC Airtac JSI Series Standard Cylinder JSI63X280STC is a genuine double acting JIS-standard air cylinder with a Ø63mm bore and 280mm 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 JSI63X280STC
Delivering 1559 N of push force at 0.5 MPa, the AirTAC JSI63X280STC is a double-acting JIS-standard profile cylinder built for tight machinery layouts. It is notably shorter and more compact than an ISO 15552 cylinder of the same 63 mm bore, saving valuable space without sacrificing power. The extruded hard-anodized aluminum barrel omits external rods to resist wear, while the two-way piston seal retains grease for a long, low-friction service life. Because this SKU includes the -S magnet, CMSE or DMSE reed and electronic switches drop directly into the side grooves for position sensing.
For practical sizing, plan for about 935 N of real work at 0.5 MPa, which safely lifts roughly 79 kg vertically with a 2:1 margin. The unit operates at 30-800 mm/s, features a 20 mm piston rod with an M18x1.5 thread, and uses G3/8 ports. Adjustable 29 mm air cushions at both ends absorb end-of-stroke impact, and the included TC trunnion mount simplifies pivoting installations.

Where the Airtac JSI Series Standard Cylinder JSI63X280STC Is Used
Pallet Diverters
Handles the lateral shifting of heavy pallets on packaging lines using the 1559 N push force and TC trunnion mount to accommodate the pivoting motion.
Vertical Material Gates
Lifts 79 kg material containment gates on warehouse sorting machines, relying on the built-in -S magnet to confirm gate closure via DMSE sensors.
Press Ejection
Ejects formed metal parts from a 63 mm bore press setup, utilizing the 29 mm adjustable air cushions to prevent harsh end-of-stroke impacts.
Is the Airtac JSI Series Standard Cylinder JSI63X280STC the Right Cylinder?
When sizing this 63 mm bore, compare your actual load against the 1559 N push force at 0.5 MPa. If your application requires less power, dropping down to the 50 mm bore yields 982 N of push force, saving air volume. If you need more thrust, stepping up to the 80 mm bore provides 2513 N. Because this 280 mm stroke is relatively long, ensure your guiding structure prevents rod bending and side loads to avoid premature seal wear. Remember that a standard cylinder drifts when air is lost or the valve is centered; the air cushion only decelerates the piston near stroke end and will not hold a load. For suspended or vertical loads, install 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 JSI Series Standard Cylinder JSI63X280STC FAQ
This 63 mm bore cylinder delivers 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 of 318 kgf at 1.0 MPa. It features a G3/8 air port, an M18x1.5 rod thread, and operates at speeds between 30-800 mm/s.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same bore. The TC designation indicates a trunnion mount interface, and the -S suffix means it has a built-in piston magnet ready for CMSE or DMSE sensors.
