Airtac JSI Series Standard Cylinder JSI32X20
The AirTAC Airtac JSI Series Standard Cylinder JSI32X20 is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 20mm 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 JSI32X20
Delivering 402 N of push force at 0.5 MPa, this double-acting 32 mm bore cylinder is built around a JIS-standard profile that is noticeably shorter than an equivalent ISO 15552 unit, saving valuable space on compact machines. 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. Air enters via a G1/8 port, driving the 12 mm rod at speeds of 30-800 mm/s.
Because this specific SKU lacks the -S magnet, it cannot host CMSE or DMSE position switches. 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. Note that the 20 mm stroke is a non-standard, made-to-order length for this series.

Where the Airtac JSI Series Standard Cylinder JSI32X20 Is Used
Small Part Ejection
Uses the 345 N pull force at 0.5 MPa to reliably eject small molded plastic parts from a tight fixture.
Short Stroke Clamping
Provides a compact 20 mm clamping action on a PCB routing station where overall machine length is restricted.
Light Diverter Gate
Pushes lightweight cardboard cartons on a packaging line, fitting neatly into the conveyor framework.
Is the Airtac JSI Series Standard Cylinder JSI32X20 the Right Cylinder?
When sizing this unit, the next bore up is the JSI40, which raises the push force to 628 N at 0.5 MPa, while the 32 mm bore shown here is the smallest available in the JSI range. Since this SKU has no -S suffix, it cannot accept magnetic sensors; if your application requires position feedback, select the JSI32X20-S variant instead. The 20 mm stroke is short enough that rod-bending side loads are minimal, but always ensure the load is guided to prevent binding.
Keep in mind that a standard double-acting cylinder will drift if air pressure is lost or the valve is centered. The adjustable air cushions at both ends only decelerate the piston near the stroke limits and do not function as a locking brake; to suspend a load safely, 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 JSI32X20 FAQ
The JSI32X20 uses a G1/8 port and generates a push force of 402 N and a pull force of 345 N at 0.5 MPa. At 0.7 MPa, the push force is 563 N and the pull force is 483 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, because this specific model lacks the -S suffix, it does not have a piston magnet and cannot accept CMSE or DMSE sensors. You would need to order the -S variant to use side-groove magnetic switches.
