Airtac JSI Series Standard Cylinder JSI40X180
The AirTAC Airtac JSI Series Standard Cylinder JSI40X180 is a genuine double acting JIS-standard air cylinder with a Ø40mm bore and 180mm 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 JSI40X180
Generating 628 N of push force at 0.5 MPa, the AirTAC JSI40X180 is a double-acting JIS-standard profile cylinder built for tight machinery layouts. It is noticeably shorter and more compact than an ISO 15552 cylinder of the same 40 mm bore, saving valuable machine space without sacrificing power. The extruded hard-anodized aluminum barrel sheds external rods to resist wear, while the two-way piston seal retains grease for a long, low-friction service life. For practical sizing, plan for about 377 N of real work at 0.5 MPa, which safely lifts roughly 32 kg vertically with a 2:1 margin.
This 180 mm stroke unit operates at 30-800 mm/s and features a G1/4 port with an M14x1.5 rod-end thread. Because this specific SKU lacks the -S magnet, it cannot host CMSE or DMSE position sensors. Adjustable air cushions at both ends absorb end-of-stroke impact to protect your mechanics. If your application demands a double rod or adjustable stroke, consider the related JSID or JSIJ series.

Where the Airtac JSI Series Standard Cylinder JSI40X180 Is Used
Package Diverter Gate
Pushes lightweight cardboard cartons on a packaging line using 628 N at 0.5 MPa, fitting neatly into tight conveyor transfer frames.
Small Part Clamp
Secures plastic housings during a hot-stamping process, using the 180 mm stroke to clear the work area for robotic loading.
Pneumatic Ejector
Kicks finished aluminum parts out of a CNC machining center, relying on the hard-anodized barrel to withstand shop-floor debris.
Is the Airtac JSI Series Standard Cylinder JSI40X180 the Right Cylinder?
When sizing this 40 mm bore actuator, compare it against its neighbors: a 32 mm JSI provides 402 N of push at 0.5 MPa for lighter loads, while a 50 mm JSI steps up to 982 N if your 628 N requirement grows. For this 180 mm stroke, side loads are moderate, but always guide the rod end to prevent bending and premature seal wear. This non-magnet SKU cannot accept switches; order the -S variant if you need drop-in CMSE or DMSE sensors in the side grooves.
Remember that a standard cylinder drifts when air is lost or the valve centers, as the cushions only decelerate the piston near stroke end rather than locking it. To hold a vertical load securely in place during an air failure, 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 JSI40X180 FAQ
The 40 mm bore generates a push of 628 N and pull of 528 N at 0.5 MPa, and a push of 879 N and pull of 739 N at 0.7 MPa. Its theoretical maximum force is 128 kgf at 1.0 MPa. The air port is G1/4.
The JSI profile is a JIS-standard cylinder that is shorter and more compact than an ISO 15552 cylinder of the same bore, saving space on machinery. It uses an extruded aluminum barrel without external rods and includes adjustable air cushions at both ends.
