Airtac JSI Series Standard Cylinder JSI32X90S
The AirTAC Airtac JSI Series Standard Cylinder JSI32X90S is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 90mm 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 JSI32X90S
Generating 402 N of push force at 0.5 MPa, the AirTAC JSI32X90S is a double-acting JIS-standard profile cylinder built for tight machinery layouts. It is purposefully shorter and more compact than an ISO 15552 cylinder of the same 32 mm bore, saving valuable real estate without sacrificing pneumatic muscle.
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 or electronic switches directly into the side grooves for position sensing. Plan for roughly 241 N of real work at 0.5 MPa, which translates to lifting about 20 kg vertically with a 2:1 safety margin. The unit features a G1/8 port, an M10x1.25 rod thread, and 20 mm adjustable air cushions at both ends to smooth out the 90 mm stroke.

Where the Airtac JSI Series Standard Cylinder JSI32X90S Is Used
Small Part Ejection
Ideal for pushing lightweight molded plastic parts out of an injection mold cavity using its 402 N push force at 0.5 MPa.
Gripper Actuation
Provides reliable 90 mm motion to open and close pneumatic grippers handling electronic connectors on an assembly line.
Diverter Arm
Drives a short-stroke diverter arm on a packaging conveyor, where the compact JIS profile saves space between belts.
Is the Airtac JSI Series Standard Cylinder JSI32X90S the Right Cylinder?
When sizing this 32 mm bore, stepping up to the JSI40X90S gives you 628 N of push at 0.5 MPa if the load demands more force, though 32 mm is the smallest available JSI bore so there is no smaller standard option. The integrated -S magnet pairs perfectly with CMSE or DMSE sensors for end-of-stroke confirmation. Remember that the standard air cushion only decelerates the piston near the end of travel; it will not hold a load if air pressure drops or the valve is centered. For vertical or suspended loads that must resist drifting during an air loss event, 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 JSI32X90S 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. The air port size is G1/8.
The JSI32X90S is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 32 mm bore, making it much easier to fit into tight machine frames.
