Airtac JSI Series Standard Cylinder JSI100X1800STC
The AirTAC Airtac JSI Series Standard Cylinder JSI100X1800STC is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 1800mm stroke, G1/2 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 JSI100X1800STC
Delivering 3927 N of push force at 0.5 MPa, this double-acting JIS-standard profile cylinder handles heavy-duty automation with ease. Its extruded hard-anodized aluminum barrel sheds external rods for a clean profile, making it significantly shorter and more compact than an equivalent ISO 15552 cylinder of the same 100 mm bore. The two-way piston seal retains grease for long, low-friction life, while the G1/2 port feeds the 32 mm rod to cycle at 30-800 mm/s.
Because this 1800 mm stroke is a non-standard, made-to-order length exceeding the 1500 mm maximum, it requires careful external guiding to prevent rod bending under side loads. The -S suffix equips the piston with a magnet for CMSE or DMSE sensors that drop directly into the side grooves. Plan for about 2356 N of real work at 0.5 MPa, which means it lifts roughly 200 kg vertically with a 2:1 safety margin.

Where the Airtac JSI Series Standard Cylinder JSI100X1800STC Is Used
Press Ejection
Uses the 3927 N push force at 0.5 MPa to eject heavy stamped metal panels from a 1000-ton hydraulic press bed over the long 1800 mm travel.
Pallet Transfer
Moves loaded pallets between machining cells, relying on the TC trunnion mount to accommodate angular misalignment across the extended stroke.
Vertical Lift Gate
Actuates a 2-meter vertical security gate, safely lifting the roughly 200 kg barrier using the magnetic piston for position feedback.
Is the Airtac JSI Series Standard Cylinder JSI100X1800STC the Right Cylinder?
When sizing this class, the neighboring JSI80X50 offers 2513 N push at 0.5 MPa for lighter frames, while stepping up to the JSI125X1800STC yields 6136 N for heavier masses. This 100 mm bore provides a strong middle ground with 5497 N push at 0.7 MPa. The included TC trunnion mount supports pivoting articulation across the long 1800 mm travel. Remember that a plain cylinder drifts when air is lost or the valve is centered; the adjustable 33 mm cushions only decelerate the piston near stroke ends, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended load.
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 JSI100X1800STC FAQ
This 100 mm bore cylinder features a G1/2 air port and a 32 mm rod. It generates 3927 N push and 3574 N pull at 0.5 MPa, 5497 N push and 5003 N pull at 0.7 MPa, with a theoretical maximum of 801 kgf at 1.0 MPa.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same bore. This space-saving extruded aluminum design omits external rods entirely.
