Airtac JSI Series Standard Cylinder JSI32X25S
The AirTAC Airtac JSI Series Standard Cylinder JSI32X25S is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 25mm 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 JSI32X25S
Designed for tight machine layouts, this 32 mm bore double-acting actuator provides 402 N of push force at 0.5 MPa while being physically shorter than an ISO 15552 cylinder of the same bore. The hard-anodized extruded aluminum barrel removes external rods for a cleaner profile, and the two-way NBR piston seal retains grease for low-friction longevity. Because this SKU includes the -S magnet, CMSE or DMSE position switches drop directly into the side grooves for immediate feedback.
Operating at 30-800 mm/s via its G1/8 port, it handles light-duty cycling with ease. 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. The adjustable 20 mm air cushions at both ends absorb impact, ensuring smooth stops across the 25 mm stroke.

Where the Airtac JSI Series Standard Cylinder JSI32X25S Is Used
Electronic Component Sorting
Pushes small PCBs or connectors into test fixtures with 402 N of force, relying on the 25 mm stroke for rapid cycling.
Small Part Ejection
Ejects lightweight plastic molded parts from a tool, using the compact profile to fit within tight press enclosures.
Package Diverting
Actuates a short diverting gate on a conveyor line, where the -S magnet confirms gate position via DMSE sensors.
Is the Airtac JSI Series Standard Cylinder JSI32X25S the Right Cylinder?
When sizing this 32 mm bore, stepping up to the JSI40X25S yields 628 N of push at 0.5 MPa if your payload increases, though there is no smaller JSI option below 32 mm. The built-in -S magnet pairs perfectly with CMSE or DMSE sensors for end-of-stroke detection. Keep in mind that standard air cushions only decelerate the piston near the end caps; they will not hold a load vertically if air pressure drops. For suspended loads that must resist drifting during a pressure loss or valve centering, add 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 JSI32X25S FAQ
This 32 mm bore model uses a G1/8 air port and an M10x1.25 rod 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.
The JSI is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 32 mm bore, saving valuable space on machinery without sacrificing the 25 mm stroke.
