Airtac JSI Series Standard Cylinder JSI32X75S
The AirTAC Airtac JSI Series Standard Cylinder JSI32X75S is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 75mm 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 JSI32X75S
Generating 402 N of push force at 0.5 MPa, this 32 mm bore pneumatic actuator fits perfectly into tight machinery where every millimeter counts. Built to JIS standard dimensions, its extruded hard-anodized aluminum profile is notably shorter and more compact than an equivalent ISO 15552 cylinder, giving you valuable real estate back on the machine bed.
The internal two-way piston seal retains grease for a long, low-friction service life, while the integrated -S piston magnet allows CMSE or DMSE switches to drop directly into the side grooves for position sensing. Because it pushes with 402 N 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 unit operates at 30-800 mm/s, features a G1/8 port, and relies on adjustable air cushions at both ends to decelerate the rod smoothly.

Where the Airtac JSI Series Standard Cylinder JSI32X75S Is Used
Small Part Ejection
Ideal for pushing lightweight molded plastic components out of an injection press, utilizing the 402 N push force to clear the mold area reliably.
Electronic Assembly Clamping
Provides precise 75 mm travel for holding delicate PCBs or housings during automated soldering, taking advantage of the compact JIS profile to save space.
Package Diverting
Handles small carton routing on a packaging line, where the built-in magnet confirms stroke completion for the PLC before the next cycle begins.
Is the Airtac JSI Series Standard Cylinder JSI32X75S the Right Cylinder?
This 32 mm bore is the smallest available in the JSI series, meaning there is no smaller option if you need to scale down. If your application requires more power, stepping up to the 40 mm bore increases the push force to 628 N at 0.5 MPa. The included -S magnet pairs perfectly with CMSE or DMSE sensors for end-of-stroke detection. For mounting flexibility, you can choose LB foot, FA/FB flange, CA/CB/CR clevis, TC/TCM1/TCM2 trunnion, or an I/Y/F/U rod knuckle.
Remember that a standard double-acting cylinder like this will drift if air pressure is lost or the valve is centered, as the adjustable cushion only decelerates the piston near the stroke ends rather than locking it. If your assembly must hold a vertical load safely during an air failure, you should add an external rod lock or a pilot-operated check valve to the setup.
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 JSI32X75S 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 rod is 12 mm, and the rod-end thread is M10x1.25.
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 aluminum barrel without external rods, saving space while maintaining the same adjustable air cushioning and sensor capabilities.
