Airtac JSI Series Standard Cylinder JSI32X120
The AirTAC Airtac JSI Series Standard Cylinder JSI32X120 is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 120mm 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 JSI32X120
Delivering 402 N of push force at 0.5 MPa, the AirTAC JSI32X120 is a JIS-standard double-acting profile cylinder built for tight machinery layouts. It is deliberately shorter and more compact than an ISO 15552 cylinder of the same 32 mm bore, saving valuable space without losing thrust. The extruded hard-anodized aluminum barrel eliminates external rods to resist wear, while the two-way piston seal retains grease for a long, low-friction service life. Because this SKU lacks the -S magnet, it cannot accept CMSE or DMSE position switches.
For practical sizing, plan for about 241 N of real work at 0.5 MPa, which safely lifts a 20 kg part vertically with a 2:1 margin. The unit features a 12 mm carbon steel rod, M10x1.25 rod thread, and a G1/8 port. Adjustable 20 mm air cushions at both ends absorb impact, and it runs at speeds between 30 and 800 mm/s.

Where the Airtac JSI Series Standard Cylinder JSI32X120 Is Used
Small Part Ejection
Pushes lightweight plastic or aluminum parts out of an injection mold using 402 N of thrust at 0.5 MPa.
Package Diverting
Actuates a routing arm on a compact packaging line to sort small cartons at speeds up to 800 mm/s.
Clamp Actuation
Secures thin sheet metal in a spot welding fixture, safely lifting 20 kg vertically with a 2:1 margin.
Is the Airtac JSI Series Standard Cylinder JSI32X120 the Right Cylinder?
If you need slightly less thrust, the next size down does not exist in the JSI series as 32 mm is the smallest bore offered. Stepping up to the JSI40X120 increases your 0.5 MPa push force to 628 N if the 402 N here is insufficient. Remember that a plain cylinder drifts when air is lost or the valve is centered; the air cushion only decelerates the piston near the end of stroke and will not hold a load. For vertical or suspended loads, install an external rod lock or a pilot-operated check valve. At 120 mm, side loading is minimal, but always guide the rod to prevent binding.
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 JSI32X120 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. The air port 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. It uses an extruded hard-anodized aluminum barrel without external rods. This specific SKU lacks the -S magnet, so it cannot use CMSE or DMSE sensors.
