Airtac JSI Series Standard Cylinder JSI32X80
The AirTAC Airtac JSI Series Standard Cylinder JSI32X80 is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 80mm stroke, G1/8 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 JSI32X80
Delivering 402 N of push force at 0.5 MPa, the AirTAC JSI32X80 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 32 mm bore, saving valuable space without sacrificing performance. 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. Because this specific SKU lacks the -S magnet, it cannot accept CMSE or DMSE position sensors.
For real-world sizing, plan for about 241 N of actual work at 0.5 MPa, which translates to lifting roughly 20 kg vertically with a 2:1 safety margin. The unit features a 12 mm carbon steel rod with an M10x1.25 thread, adjustable air cushions at both ends, and a G1/8 port. It operates smoothly between 30 and 800 mm/s across a 0.15-1.0 MPa pressure range.

Where the Airtac JSI Series Standard Cylinder JSI32X80 Is Used
Small Part Ejection
Uses the 345 N pull force at 0.5 MPa to reliably strip small plastic mouldings from an injection press tool.
Package Diverting
Pops up a lightweight aluminum deflector gate for 80 mm to redirect small cartons on a packaging line.
Clamp Actuation
Secures thin sheet metal brackets during a light-duty robotic drilling or riveting operation.
Is the Airtac JSI Series Standard Cylinder JSI32X80 the Right Cylinder?
When sizing this 32 mm bore, stepping up to the JSI40X80 provides a substantial boost to 628 N of push force at 0.5 MPa, while there is no smaller JSI option available below 32 mm. This 80 mm stroke is well within standard length limits, so no side-load concerns arise. Remember that a standard cylinder drifts if air pressure drops or the valve is centered; the adjustable cushion only decelerates the piston near the end of stroke and will not hold a load. For vertical applications requiring position holding, install an external rod lock or a pilot-operated check valve. Since this configuration omits the -S magnet, you must select a -S variant if you need to mount CMSE or DMSE sensors in the side grooves.
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 JSI32X80 FAQ
This 32 mm bore cylinder delivers 402 N push and 345 N pull at 0.5 MPa, 563 N push and 483 N pull at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa. The air port size is G1/8.
The JSI is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same bore. It uses an extruded aluminum barrel without external rods to save machine space.
