Airtac JSI Series Standard Cylinder JSI32X250SFA
The AirTAC Airtac JSI Series Standard Cylinder JSI32X250SFA is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 250mm 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 JSI32X250SFA
Delivering 402 N of push force at 0.5 MPa, this double-acting 32 mm bore cylinder is built around a JIS-standard profile that is noticeably shorter and more compact than an equivalent ISO 15552 unit. The hard-anodized extruded aluminum barrel omits external rods to resist wear, while a two-way piston seal retains grease for a long, low-friction service life across the 250 mm stroke.
Because the code includes an S, a built-in magnet lets CMSE or DMSE sensors drop directly into the side grooves for position detection. 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 unit features a G1/8 port, an M10x1.25 rod thread, and adjustable air cushions at both ends.

Where the Airtac JSI Series Standard Cylinder JSI32X250SFA Is Used
Small Part Ejection
Pushes lightweight plastic moldings out of an injection press using 402 N of force at 0.5 MPa over the 250 mm travel.
Diverting Mechanism
Actuates a routing flap on a packaging line, where the compact JIS profile saves valuable space inside the machine frame.
Lab Test Fixture
Applies a controlled clamping pressure to delicate electronics, lifting roughly 20 kg with a safe 2:1 margin.
Is the Airtac JSI Series Standard Cylinder JSI32X250SFA the Right Cylinder?
If 402 N of push is insufficient, stepping up to the 50 mm bore yields 982 N at 0.5 MPa; there is no smaller JSI bore below 32 mm. The FA flange mounting provides a solid face-mount interface, and the included S magnet ensures compatibility with reed or electronic switches. For this 250 mm stroke, ensure external guide rails support any lateral load to prevent rod bending, as the piston rod alone should not absorb side forces. Note that standard air cushions only decelerate the piston near the end of travel; to hold a load vertically during air loss or valve centering, add an external rod lock or 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 JSI32X250SFA 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 is 82 kgf at 1.0 MPa, and the air port is G1/8.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 32 mm bore. It uses an FA flange for mounting and includes an S magnet for CMSE/DMSE sensors.
