Airtac JSI Series Standard Cylinder JSI32X300
The AirTAC Airtac JSI Series Standard Cylinder JSI32X300 is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 300mm 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 JSI32X300
Delivering 402 N of push force at 0.5 MPa, this double-acting JIS-standard profile cylinder saves valuable machine space by being shorter and more compact than an ISO 15552 cylinder of the same 32 mm bore. The extruded hard-anodized aluminum barrel omits external rods to resist wear, while a two-way piston seal retains grease for long, low-friction life. It features a 12 mm rod, M10x1.25 rod-end thread, and a G1/8 port.
Because this SKU lacks the -S magnet, it cannot accept CMSE or DMSE position switches. 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.

Where the Airtac JSI Series Standard Cylinder JSI32X300 Is Used
Small Parts Ejection
Pushes lightweight plastic mouldings out of a 32 mm bore fixture using 402 N of thrust at 0.5 MPa.
Sorter Diverter
Extends 300 mm to deflect small electronic packages on a conveyor belt without taking up much frame depth.
Light Duty Gate
Actuates a compact safety guard on a benchtop assembly machine, benefiting from the hard-anodized barrel.
Is the Airtac JSI Series Standard Cylinder JSI32X300 the Right Cylinder?
When sizing this 32 mm bore, stepping up to the JSI40X300 increases thrust to 628 N at 0.5 MPa, while there is no smaller JSI option below 32 mm. Since this is a 300 mm stroke, external guides are strongly recommended to prevent rod bending and absorb side loads. This non-magnet model cannot hold a position if air pressure drops; the end-of-stroke air cushion only decelerates the piston. For secure load holding, 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 JSI32X300 FAQ
The JSI32X300 delivers a push force of 402 N and a pull force of 345 N at 0.5 MPa, or 563 N push and 483 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa. It uses a G1/8 air port and operates at speeds between 30 and 800 mm/s.
No, because this specific SKU does not include the -S magnet, it cannot accept CMSE or DMSE magnetic switches. You would need the JSI32X300-S variant for sensor integration. The cylinder mounts via LB foot, FA/FB flange, CA/CB clevis, or TC trunnion brackets.
