Airtac JSI Series Standard Cylinder JSI50X600
The AirTAC Airtac JSI Series Standard Cylinder JSI50X600 is a genuine double acting JIS-standard air cylinder with a Ø50mm bore and 600mm 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 JSI Series Standard Cylinder JSI50X600
Delivering 982 N of push force at 0.5 MPa, the AirTAC JSI50X600 is a double-acting JIS-standard profile cylinder built for long-reach tasks. Its extruded hard-anodized aluminum barrel omits external rods, making the unit shorter and more compact than an ISO 15552 cylinder of the same 50 mm bore. The internal two-way piston seal retains grease, ensuring low-friction operation over a long service life.
Because this SKU lacks the -S magnet, it cannot accept CMSE or DMSE position switches. For sizing, plan for about 589 N of real work at 0.5 MPa, which translates to lifting roughly 50 kg vertically with a 2:1 safety margin. The unit features a G1/4 port, an M18x1.5 rod thread, and adjustable air cushions at both ends to decelerate the piston smoothly.

Where the Airtac JSI Series Standard Cylinder JSI50X600 Is Used
Packaging Line Diverter
Pushes heavy cardboard cartons across a 600 mm transfer gap with 982 N of force at 0.5 MPa, relying on the end cushions to stop the rod smoothly.
Palletizing Push-Off
Sweeps layered product onto a waiting pallet, where the compact JIS profile saves valuable floor space compared to standard ISO 15552 units.
Automated Gate Arm
Acts as a long-throw actuator for a machinery access gate, moving 600 mm while an external guide rod absorbs lateral wind loads.
Is the Airtac JSI Series Standard Cylinder JSI50X600 the Right Cylinder?
When sizing this 50 mm bore, dropping down to a JSI40 yields 628 N of push at 0.5 MPa, while stepping up to a JSI63 provides 1559 N. Keep in mind that a standard cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift, and the cushion only decelerates near stroke end. For a suspended load, install an external rod lock or a pilot-operated check valve. Additionally, the 600 mm stroke demands attention to side loads—use an external guide to prevent rod bending and premature seal wear.
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 JSI50X600 FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it delivers 1374 N push and 1154 N pull. The theoretical maximum is 200 kgf at 1.0 MPa, and the air port size is G1/4.
No, this specific SKU does not include a magnet, so CMSE or DMSE switches will not function. You would need the JSI50X600-S variant to enable side-groove position sensing.
