Airtac JSI Series Standard Cylinder JSI32X320S
The AirTAC Airtac JSI Series Standard Cylinder JSI32X320S 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 JSI32X320S
Delivering 402 N of push force at 0.5 MPa, this double-acting 32 mm bore cylinder is built for tight machinery layouts where an ISO 15552 equivalent of the same bore simply will not fit. The JIS-standard extruded aluminium barrel keeps the overall envelope shorter and lighter, while the hard-anodized profile resists wear without needing external rods. A heterogeneous two-way piston seal retains grease for a long, low-friction service life.
Because the SKU carries the -S suffix, a built-in piston magnet lets you drop CMSE or DMSE reed and electronic switches directly into the side sensor grooves. 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. Air enters via the G1/8 port, and adjustable 20 mm cushions at both ends decelerate the 12 mm rod smoothly across the 320 mm travel.

Where the Airtac JSI Series Standard Cylinder JSI32X320S Is Used
Small Parts Ejection
Pushes lightweight plastic mouldings out of a 32 mm fixture using 402 N of force, with the 320 mm stroke reaching across the press bed.
Package Diverter
Actuates a routing flap on a compact packaging line where the shorter JIS profile avoids clashing with adjacent conveyor rollers.
Bin Lid Actuation
Raises and lowers a 15 kg hopper lid vertically, safely within the 20 kg vertical lift capacity calculated at a 2:1 margin.
Is the Airtac JSI Series Standard Cylinder JSI32X320S the Right Cylinder?
When sizing this 32 mm bore, stepping down is not an option within the JSI family as this is the smallest available diameter. If you need more power, the next size up is the 40 mm bore, which raises the push force to 628 N at 0.5 MPa. For this 320 mm stroke, the extended length makes the 12 mm rod vulnerable to bending, so an external guide or load-bearing rail should be used to prevent side-load damage. The included -S magnet pairs perfectly with CMSE or DMSE sensors for position confirmation.
Keep in mind that a standard pneumatic cylinder drifts when air pressure is lost or the valve is centered; the adjustable cushion only slows the piston near the end of travel and acts as no brake. If your application requires the load to stay put during an air failure, fit 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 JSI32X320S FAQ
This 32 mm bore cylinder features a G1/8 air port and a 12 mm rod with an M10x1.25 thread. The thrust output is 402 N push and 345 N pull at 0.5 MPa, increasing to 563 N push and 483 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
The JSI is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same bore, saving valuable space on tight machines. It uses an extruded hard-anodized aluminum barrel with no external rods. Because this model includes the -S magnet, you can easily install CMSE or DMSE sensors in the side grooves.
