Airtac JSI Series Standard Cylinder JSI32X80STC
The AirTAC Airtac JSI Series Standard Cylinder JSI32X80STC is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 80mm 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 JSI32X80STC
Delivering 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 equivalent ISO 15552 unit of the same 32 mm bore. The extruded hard-anodized aluminum barrel contains no external rods, while the two-way piston seal retains grease for extended, low-friction operation. Because the SKU includes the -S suffix, a built-in piston magnet is present, allowing CMSE or DMSE switches to drop directly into the side grooves for position sensing.
For practical sizing, 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 an M10x1.25 rod thread, a G1/8 port, and 20 mm adjustable air cushions at both ends to smooth out the 80 mm travel. The TC trunnion mount provides a pivoting axis that handles slight misalignment, and the cylinder operates smoothly across a 30-800 mm/s speed range.

Where the Airtac JSI Series Standard Cylinder JSI32X80STC Is Used
Small Part Ejection
Uses the 345 N pull force at 0.5 MPa to reliably strip small plastic molded parts from a die plate.
Package Diverting
Actuates a lightweight routing gate on a packaging line, where the compact JIS profile keeps the footprint tight.
Clamp Actuation
Secures thin sheet metal in a CNC fixture, lifting about 20 kg vertically with a 2:1 safety margin.
Is the Airtac JSI Series Standard Cylinder JSI32X80STC the Right Cylinder?
When sizing this 32 mm bore, stepping up to the JSI40X80STC yields 628 N of push force at 0.5 MPa if your load demands more authority, as there is no smaller bore in the JSI lineup. For the current 80 mm stroke, side-load risks are minimal, but any future upgrade to strokes of 300 mm or longer will require external guide rails to prevent rod bending. Remember that a standard cylinder drifts when air is lost or the valve is centered; the cushions only decelerate the piston near the end of travel and do not act as a brake. To suspend a load safely mid-stroke, fit 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 JSI32X80STC 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 TC trunnion allows pivoting to accommodate slight non-parallelism between the cylinder and the load path. Additionally, the JIS profile construction is physically shorter and more compact than a same-bore ISO 15552 cylinder, saving space without losing the 80 mm stroke capability.
