Airtac JSI Series Standard Cylinder JSI32X400S
The AirTAC Airtac JSI Series Standard Cylinder JSI32X400S is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 400mm 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 JSI32X400S
Generating 402 N of push force at 0.5 MPa, this 32 mm bore double-acting actuator fits tight machinery where an ISO 15552 equivalent of the same bore would be too long. The extruded hard-anodized aluminum barrel lacks external rods, and the two-way piston seal retains grease for a low-friction service life. Because this SKU includes the -S magnet, you can drop CMSE or DMSE sensors directly into the side grooves for position detection.
At 0.5 MPa you can plan for roughly 241 N of real work, which means it lifts about 20 kg vertically with a 2:1 safety margin. The G1/8 port feeds the chambers, and adjustable air cushions at both ends absorb kinetic energy near the stroke limits. For tasks needing opposing or variable strokes, consider the related JSID double-rod or JSIJ adjustable-stroke variants.

Where the Airtac JSI Series Standard Cylinder JSI32X400S Is Used
Package Diverter Gate
Pushes lightweight cardboard cartons on a sorting line using 402 N of push force at 0.5 MPa, fitting neatly within tight conveyor frame clearances.
Small Part Ejection
Ejects molded plastic components from a press using the 400 mm stroke, relying on the -S magnet and DMSE sensors to confirm full retraction.
Vertical Tray Lifter
Raises stacked product trays weighing up to 20 kg vertically, operating safely within the 2:1 margin of the 0.5 MPa push rating.
Is the Airtac JSI Series Standard Cylinder JSI32X400S the Right Cylinder?
When sizing this 32 mm bore, stepping up to the 40 mm bore raises the push force to 628 N at 0.5 MPa, while 32 mm is the smallest available JSI option. The 400 mm stroke is fully standard, but at this length the 12 mm rod is susceptible to bending under lateral stress; use an external guide rail to prevent side-load damage. Since this is a double-acting cylinder, exhausting the air or centering the valve lets the piston drift, as the cushions only decelerate at the ends. To hold a load securely, install 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 JSI32X400S FAQ
The 32 mm bore provides 402 N push and 345 N pull at 0.5 MPa, or 563 N push and 483 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa. It uses a G1/8 air port, a 12 mm rod, and has a 20 mm adjustable cushion at each end.
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 extruded aluminum barrel without external rods to save space, and the -S suffix means it has a built-in magnet for CMSE or DMSE sensors.
