Airtac JSI Series Standard Cylinder JSI32X185S
The AirTAC Airtac JSI Series Standard Cylinder JSI32X185S is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 185mm 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 JSI32X185S
Delivering 402 N of push force at 0.5 MPa, the AirTAC JSI32X185S is a double-acting JIS-standard profile cylinder built for tight machinery layouts. It is deliberately shorter and more compact than an ISO 15552 cylinder of the same 32 mm bore, saving valuable space without sacrificing performance. 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 the model includes the -S suffix, it features a built-in piston magnet for CMSE or DMSE switches that drop directly into the side sensor grooves. For real-world sizing, plan for about 241 N of actual work at 0.5 MPa, which translates to lifting roughly 20 kg vertically with a 2:1 safety margin. The unit uses a G1/8 port, an M10x1.25 rod thread, and adjustable air cushions at both ends to smoothly decelerate the 185 mm stroke.

Where the Airtac JSI Series Standard Cylinder JSI32X185S Is Used
Small Part Ejection
Ideal for pushing lightweight molded plastic parts out of an injection mold, utilizing the 241 N safe working load to reliably clear the tooling.
Package Diverting
Sort small cartons on a packaging line where the 20 kg vertical lift capacity is more than enough to actuate a routing flap or pusher arm.
Clamp Actuation
Secures thin electronic PCBs during automated soldering, taking advantage of the compact JIS profile to fit within dense assembly machinery.
Is the Airtac JSI Series Standard Cylinder JSI32X185S the Right Cylinder?
This 32 mm bore is the smallest available in the JSI series, so if your application requires less force you would need to look outside this family. Moving up to the JSI40X185S increases the push force to 628 N at 0.5 MPa. At 185 mm of travel, the stroke is well within safe parameters, though any application exceeding 300 mm should incorporate external guide rails to prevent rod bending under side loads. Since this SKU carries the -S magnet, it is fully ready for CMSE or DMSE position sensing. Remember that standard pneumatic operation will not hold a load securely if air pressure drops or the valve is centered; the piston will drift. To maintain vertical position, integrate 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 JSI32X185S FAQ
This 32 mm bore cylinder features a G1/8 port and generates 402 N push / 345 N pull at 0.5 MPa, and 563 N push / 483 N pull at 0.7 MPa. The theoretical maximum force is 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. Additionally, the -S suffix indicates a built-in magnet, allowing CMSE or DMSE switches to be installed directly into the side grooves for position detection.
