Airtac JSI Series Standard Cylinder JSI32X450STC
The AirTAC Airtac JSI Series Standard Cylinder JSI32X450STC is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 450mm 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 JSI32X450STC
Generating 402 N of push force at 0.5 MPa, this double-acting 32 mm bore cylinder is engineered for tight machinery envelopes where a standard ISO 15552 unit simply will not fit. The JIS-standard extruded aluminium profile is noticeably shorter than a same-bore ISO equivalent, saving valuable space without sacrificing performance. Its hard-anodized barrel omits external rods to resist wear, while the heterogeneous two-way piston seal retains grease for a long, low-friction service life.
Because air extends and retracts the 12 mm rod, you can 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 -S suffix denotes a built-in piston magnet, allowing CMSE or DMSE electronic switches to drop directly into the side grooves for position sensing. Air enters via the G1/8 port, and adjustable 20 mm cushions at both ends absorb kinetic energy near the stroke limits.

Where the Airtac JSI Series Standard Cylinder JSI32X450STC Is Used
PCB Panel Push-off
Deploys the 450 mm stroke to separate routed printed circuit boards from a carrier panel, using the 402 N push force to snap perforated tabs cleanly without stressing the substrate.
Package Lane Diverting
Extends across a narrow belt to act as a sorting gate for lightweight cardboard cartons, benefiting from the compact JIS profile to fit between tight conveyor frames.
Small Part Ejection
Pushes machined plastic components out of an injection mold area, relying on the built-in magnet and DMSE sensor to confirm full ejection before the mold closes.
Is the Airtac JSI Series Standard Cylinder JSI32X450STC the Right Cylinder?
When sizing this 450 mm stroke unit, verify your force needs: dropping down is not an option as 32 mm is the smallest JSI bore, but stepping up to the 40 mm bore provides 628 N of push at 0.5 MPa if your load increases. For this 450 mm extension, mounting via the included TC trunnion helps manage moments, yet you should still incorporate an external guide to prevent rod bending under side loads. Remember that the adjustable cushion only decelerates the piston near the end of travel; it will not hold a load vertically if air pressure drops. To prevent drifting when the valve is centered or air is lost, 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 JSI32X450STC FAQ
This 32 mm bore cylinder uses a G1/8 air port and a 12 mm rod with an M10x1.25 thread. It generates 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.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same bore, utilizing an extruded aluminum barrel without external rods. The -S magnet enables CMSE/DMSE sensors, and the TC trunnion mount allows pivoting installations.
