Airtac JSI Series Standard Cylinder JSI32X400STC
The AirTAC Airtac JSI Series Standard Cylinder JSI32X400STC 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 JSI32X400STC
Delivering 402 N of push force at 0.5 MPa, this double-acting 32 mm bore cylinder is built for tight machinery layouts where an ISO 15552 equivalent of the same bore simply will not fit. The extruded hard-anodized aluminum profile keeps the total envelope shorter, while the two-way piston seal retains grease for a long, low-friction service life across the 400 mm travel.
Because the -S suffix denotes a built-in piston magnet, you can drop CMSE or DMSE reed or electronic switches directly into the side grooves for position detection. 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 G1/8 port, an M10x1.25 rod thread, and adjustable 20 mm air cushions at both ends to decelerate the payload smoothly.

Where the Airtac JSI Series Standard Cylinder JSI32X400STC Is Used
PCB Handling Conveyor
Uses the compact 32 mm profile and 400 mm stroke to push circuit boards between processing stations, relying on the -S magnet for precise end-of-travel detection.
Lightweight Parts Sorter
Lifts electronic components weighing up to 20 kg vertically with a 2:1 margin, taking advantage of the 402 N push force at 0.5 MPa to actuate routing gates.
Lab Automation Dispenser
Moves a dispensing head across a 400 mm axis where space is restricted, benefiting from the shorter JIS profile compared to standard ISO 15552 units.
Is the Airtac JSI Series Standard Cylinder JSI32X400STC the Right Cylinder?
When sizing this 32 mm bore, stepping down is not an option as it is the smallest available JSI, but stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa if your payload increases. The included TC trunnion mount provides a pivoting axis that helps accommodate minor misalignment, which is especially relevant for this 400 mm stroke. At this extended length, you must support the load with external guides to prevent rod bending and premature seal wear from side-load forces.
Remember that the adjustable air cushion only decelerates the piston near the stroke ends and does not function as a braking device. If your application must hold a vertical load safely when air pressure drops or the valve is centered, install an external rod lock or a pilot-operated check valve to prevent drift.
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 JSI32X400STC FAQ
This 32 mm bore model features a G1/8 port and generates 402 N push / 345 N pull at 0.5 MPa, 563 N push / 483 N pull at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa.
The TC trunnion mount allows pivoting attachment to handle angular misalignment, while the -S suffix means a magnet is built into the piston, enabling CMSE or DMSE sensors to be installed in the side grooves for position feedback.
