Airtac JSI Series Standard Cylinder JSI32X320
The AirTAC Airtac JSI Series Standard Cylinder JSI32X320 is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 320mm 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 JSI32X320
Generating 402 N of push force at 0.5 MPa, this double-acting JIS-standard profile cylinder saves valuable space on tight machines by being noticeably shorter than an ISO 15552 unit of the same 32 mm bore. The extruded hard-anodized aluminum barrel features no external rods, while the two-way piston seal retains grease for a long, low-friction service life. Air connects via a G1/8 port.
For practical sizing, plan for around 241 N of real work at 0.5 MPa, which translates to lifting about 20 kg vertically with a 2:1 safety margin. Because this specific SKU lacks the -S magnet, it cannot accept CMSE or DMSE position sensors. The adjustable 20 mm air cushions at both ends decelerate the piston smoothly near stroke end.

Where the Airtac JSI Series Standard Cylinder JSI32X320 Is Used
Small Part Ejection
Pushes light plastic parts out of an injection mold cavity using 402 N of force over a 320 mm reach.
Carton Diverting
Extends across a packaging conveyor lane to sort small cardboard boxes on a tight 32 mm pitch machine.
Light Clamping
Holds thin aluminum brackets in place for a secondary drilling operation without marking the surface.
Is the Airtac JSI Series Standard Cylinder JSI32X320 the Right Cylinder?
When sizing this 32 mm bore, stepping up to the JSI40X320 yields 628 N of push force at 0.5 MPa, while no smaller JSI bore exists if you need to reduce footprint. Since the 320 mm stroke creates a long lever arm, use an external guide to prevent rod bending and absorb side loads. Note that air loss will cause the piston to drift; the cushion only decelerates and does not lock. For a held load, add an external rod lock or 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 JSI32X320 FAQ
At 0.5 MPa it provides 402 N push and 345 N pull. At 0.7 MPa it provides 563 N push and 483 N pull. The theoretical maximum is 82 kgf at 1.0 MPa, and the air port is G1/8.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 32 mm bore. The extruded barrel has no external rods, saving space while retaining full functionality.
