Airtac JSI Series Standard Cylinder JSI32X90
The AirTAC Airtac JSI Series Standard Cylinder JSI32X90 is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 90mm 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 JSI32X90
Delivering 402 N of push force at 0.5 MPa, this double-acting 32 mm bore unit is built for tight spaces where every millimeter counts. As a JIS-standard profile cylinder, it is notably shorter and more compact than an ISO 15552 cylinder of the same bore, giving you valuable real estate back on dense machinery. The extruded hard-anodized aluminum barrel sheds 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 switches. Plan for roughly 241 N of actual work at 0.5 MPa, which translates to lifting about 20 kg vertically with a 2:1 safety margin. The unit features a G1/8 port, an M10x1.25 rod thread, and adjustable air cushions at both ends to smooth out the 90 mm stroke.

Where the Airtac JSI Series Standard Cylinder JSI32X90 Is Used
Small Part Ejection
Pushes lightweight plastic mouldings out of an injection press with 402 N of force at 0.5 MPa, fitting neatly into tight tooling envelopes.
Package Diverting
Actuates a short 90 mm stroke diverter arm on a packaging line to sort small cartons without consuming excessive frame width.
Clamp Actuation
Secures electronic PCBs during routing, where the compact JIS profile leaves room for adjacent spindle motors and tooling.
Is the Airtac JSI Series Standard Cylinder JSI32X90 the Right Cylinder?
If 402 N of push is too much for your fixture, AirTAC does not make a smaller JSI bore, so you would need to look at smaller alternative series. Stepping up to the JSI40X90 gives you 628 N at 0.5 MPa if you need more punch. Remember that a standard cylinder drifts when air is lost or the valve centers; the cushions only decelerate the piston near the end of travel, so fit an external rod lock or pilot-operated check valve if you must hold a vertical load. At a 90 mm stroke, side-load risks are minimal, but always ensure rigid mounting via LB foot, FA flange, or an I/Y knuckle.
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 JSI32X90 FAQ
At 0.5 MPa it provides 402 N push and 345 N pull. At 0.7 MPa it yields 563 N push and 483 N pull. The theoretical maximum is 82 kgf at 1.0 MPa. The air port is G1/8.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSE or DMSE switches. You would need the JSI32X90-S variant to utilize the side sensor grooves.
