Airtac JSI Series Standard Cylinder JSI32X5S
The AirTAC Airtac JSI Series Standard Cylinder JSI32X5S is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 5mm 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 JSI32X5S
Designed for very short stroke clamping, the AirTAC JSI32X5S is a double-acting JIS-standard profile cylinder. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, fitting neatly into tight machinery where a same-bore ISO 15552 unit would be too long.
The extruded hard-anodized aluminum barrel omits external rods to resist wear, while the two-way piston seal retains grease for a long, low-friction life. Because this SKU carries the -S magnet, you can drop CMSE or DMSE reed and electronic switches directly into the side grooves for position detection. Plan for roughly 241 N of actual work at 0.5 MPa, which means it lifts about 20 kg vertically with a 2:1 safety margin. Air connects via a G1/8 port, and adjustable cushions at both ends decelerate the 12 mm rod near stroke end.

Where the Airtac JSI Series Standard Cylinder JSI32X5S Is Used
Micro-Clamping Stations
Provides 402 N of push at 0.5 MPa to hold small aluminum brackets during light CNC milling operations.
Ejector Pins
Uses the 5 mm stroke to eject small molded plastic parts from a cavity quickly without consuming much axial space.
Gate Diverters
Shifts a short diverter flap on a packaging line to sort small cartons, relying on the -S magnet for position feedback.
Is the Airtac JSI Series Standard Cylinder JSI32X5S the Right Cylinder?
As the smallest bore in the JSI range, there is no smaller standard option below 32 mm. If you need more clamping power, stepping up to the JSI40X5S raises the 0.5 MPa push force to 628 N. This 5 mm stroke is ideal for micro-movements, but remember that a plain cylinder drifts if air is lost or the valve is centered; the air cushion only decelerates the piston and does not act as a lock. For a held load, specify an external rod lock or a pilot-operated check valve. The M10x1.25 rod thread accepts standard I, Y, F, or U knuckles.
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 JSI32X5S FAQ
At 0.5 MPa it provides 402 N push and 345 N pull. At 0.7 MPa it provides 563 N push and 483 N pull. The theoretical maximum force is 82 kgf at 1.0 MPa, and the air port size is G1/8.
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 tight machines.
