Airtac JSI Series Standard Cylinder JSI32X50FB
The AirTAC Airtac JSI Series Standard Cylinder JSI32X50FB is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 50mm 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 JSI32X50FB
Generating 402 N of push force at 0.5 MPa, this double-acting JIS-standard profile cylinder saves valuable machine space by being shorter and more compact than an ISO 15552 cylinder of the same 32 mm bore. The extruded hard-anodized aluminum barrel lacks external rods to resist wear, while the two-way piston seal retains grease for a long, low-friction service life. Because this specific SKU lacks the -S magnet, it cannot accept CMSE or DMSE position switches.
In practical terms, plan for about 241 N of real work at 0.5 MPa, which translates to lifting roughly 20 kg vertically with a 2:1 safety margin. The unit features a 12 mm carbon steel rod with an M10x1.25 thread, a G1/8 port, and 20 mm adjustable air cushions at both ends to smoothly decelerate the piston.

Where the Airtac JSI Series Standard Cylinder JSI32X50FB Is Used
Small Part Ejection
Provides reliable 402 N push at 0.5 MPa to eject small molded plastic parts from a conveyor chute on an assembly line.
Clamp Actuation
Secures thin aluminum brackets in a machining fixture using the FB flange mount to resist lateral shifting during light drilling.
Lab Dispenser Push
Drives a syringe mechanism for adhesive dispensing, where the compact JIS profile saves space on a crowded laboratory bench.
Is the Airtac JSI Series Standard Cylinder JSI32X50FB the Right Cylinder?
If 402 N of push is excessive for your task, AirTAC does not offer a smaller JSI bore, so you must look outside the series; stepping up to the JSI40X50FB raises the 0.5 MPa push force to 628 N. This model includes an FB front flange mount for secure fixation. Note that a standard cylinder drifts if air pressure is lost or the valve is centered, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended load. The 50 mm stroke is short enough to avoid rod-bending concerns.
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 JSI32X50FB 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.
No, because this SKU does not include the -S magnet, it cannot accept CMSE or DMSE magnetic switches. You must select the JSI32X50-SFB variant to use side-groove sensors.
