Airtac JSI Series Standard Cylinder JSI32X450S
The AirTAC Airtac JSI Series Standard Cylinder JSI32X450S is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 450mm 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 JSI32X450S
Generating 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. Fitted with a G1/8 port and a 12 mm rod, it operates smoothly between 30 and 800 mm/s.
Because the -S suffix provides a built-in piston magnet, CMSE or DMSE switches drop directly into the side grooves for precise position detection. Plan for about 241 N of real work at 0.5 MPa, which means it lifts roughly 20 kg vertically with a 2:1 safety margin. The adjustable 20 mm air cushions at both ends decelerate the piston near stroke end, but remember they do not function as a lock if air pressure is lost.

Where the Airtac JSI Series Standard Cylinder JSI32X450S Is Used
Light-Part Ejection
Uses the 402 N push force to reliably knock small plastic molded components out of a tooling cavity without damaging the part surface.
Package Sorting Diverter
Leverages the 450 mm stroke to push lightweight cardboard cartons from a main production line onto a secondary packaging belt.
Tray Indexing Gate
Actuates a sliding gate mechanism in a compact warehouse routing station, taking advantage of the space-saving JIS profile dimensions.
Is the Airtac JSI Series Standard Cylinder JSI32X450S the Right Cylinder?
When sizing this 32 mm bore, dropping down is not an option as it is the smallest available JSI, but stepping up to the 40 mm bore increases the 0.5 MPa push force to 628 N for heavier cycles. The included -S magnet pairs perfectly with CMSE or DMSE sensors, and mounting is highly versatile with LB foot, FA/FB flange, CA/CB/CR clevis, TC/TCM1/TCM2 trunnion, or I/Y/F/U rod knuckles.
At a 450 mm stroke, the 12 mm rod is susceptible to bending under lateral stress, so an external guide bearing should be used to prevent side-load damage. Also, a standard double-acting cylinder drifts when air is lost or a valve is centered; add an external rod lock or pilot-operated check valve if the load must be held securely.
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 JSI32X450S FAQ
This 32 mm bore cylinder features a G1/8 port and delivers a push force of 402 N and a pull force of 345 N at 0.5 MPa. At 0.7 MPa, the push increases to 563 N and the pull to 483 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
The adjustable air cushions only decelerate the piston near the stroke ends and will not hold a load if air is lost; use an external rod lock for vertical holding. The -S suffix indicates a built-in piston magnet, allowing CMSE or DMSE electronic or reed switches to be installed in the side grooves for position sensing.
