Airtac JSI Series Standard Cylinder JSI32X900S
The AirTAC Airtac JSI Series Standard Cylinder JSI32X900S is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 900mm 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 JSI32X900S
Delivering 402 N of push force at 0.5 MPa, this double-acting JIS-standard profile cylinder saves valuable machine space by being noticeably shorter than an ISO 15552 cylinder of the same 32 mm bore. The extruded hard-anodized aluminum barrel omits external rods to resist wear, while the two-way piston seal retains grease for a long, low-friction service life. Because this SKU includes the -S magnet, you can drop CMSE or DMSE reed and electronic switches directly into the side grooves for position detection.
With a 900 mm stroke, plan for about 241 N of real work at 0.5 MPa, which is roughly 60 percent of the theoretical rating. That translates to lifting about 20 kg vertically with a 2:1 safety margin. The G1/8 port and M10x1.25 rod thread keep the pneumatic footprint small, and adjustable 20 mm air cushions at both ends decelerate the piston smoothly across its 30-800 mm/s operating speed.

Where the Airtac JSI Series Standard Cylinder JSI32X900S Is Used
Long-Reach Pick & Place
Moves lightweight electronic connectors along a 900 mm axis in PCB assembly lines, relying on the compact 32 mm JIS profile to fit within tight machine enclosures.
Lab Sample Transport
Pushes sample trays between testing stations in automated diagnostic equipment, where the 20 kg vertical lift margin and smooth 20 mm cushions prevent jarring stops.
Bin Diverting Arm
Acts as a long extending diverter for small parts on a gravity conveyor, using the -S magnet and DMSE sensors to confirm full extension before a box passes.
Is the Airtac JSI Series Standard Cylinder JSI32X900S the Right Cylinder?
When sizing this 32 mm bore, moving down is not an option as it is the smallest JSI available. If you need more power, the next bore up is the 40 mm class, which provides 628 N of push at 0.5 MPa compared to this model's 402 N. Because a standard cylinder drifts when air is lost or a valve is centered, you must add an external rod lock or a pilot-operated check valve if the load needs to be held securely in place. The end-of-stroke cushions only decelerate the piston; they do not act as a brake.
At a 900 mm stroke, the 12 mm piston rod is highly susceptible to bending under lateral stress. You must support the load with external linear guides to prevent side-loading and ensure the rod pushes purely axially.
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 JSI32X900S FAQ
This 32 mm bore cylinder uses a G1/8 air port and an M10x1.25 rod thread. It generates 402 N push and 345 N pull at 0.5 MPa, 563 N push and 483 N pull at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa.
The JSI is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same bore, saving space on tight machines. It uses an extruded aluminum barrel without external rods and is not dimensionally interchangeable with ISO 15552.
