Airtac JSI Series Standard Cylinder JSI32X140S
The AirTAC Airtac JSI Series Standard Cylinder JSI32X140S is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 140mm 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 JSI32X140S
Delivering 402 N of push force at 0.5 MPa, this double-acting 32 mm bore unit is built around a JIS-standard extruded hard-anodized aluminum profile that is notably shorter and more compact than an equivalent ISO 15552 cylinder. The 140 mm stroke operates at 30-800 mm/s, utilizing a two-way NBR piston seal that retains grease for low-friction longevity. Because this SKU includes the -S magnet, you can drop CMSE or DMSE reed and electronic switches directly into the side sensor grooves for position detection.
For practical sizing, plan for a safe working load of about 241 N, which translates to lifting roughly 20 kg vertically with a 2:1 safety margin. The G1/8 port and M10x1.25 rod thread keep the pneumatic footprint small, while the 20 mm adjustable air cushions at both ends absorb end-of-stroke impact. If you need opposing synchronous movement or a custom stroke length, consider the related JSID double-rod or JSIJ adjustable-stroke variants.

Is the Airtac JSI Series Standard Cylinder JSI32X140S the Right Cylinder?
When sizing this 32 mm bore, there is no smaller JSI option below it, so if your load drops under 241 N of real work, look at reducing pressure rather than the bore. If you need more force, stepping up to the 40 mm bore yields 628 N of push at 0.5 MPa. At 140 mm stroke, side-load risks are minimal, but always ensure rigid mounting using LB foot, FA/FB flange, or TC trunnion brackets. Remember that a standard cylinder drifts if air pressure is lost or the valve is centered; the cushions only decelerate the piston near the end caps and will not hold a load, so specify an external rod lock or pilot-operated check valve for vertical safety.
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 JSI32X140S FAQ
This 32 mm bore cylinder features a G1/8 air port and an M10x1.25 rod thread. It generates 402 N push and 345 N pull at 0.5 MPa, 563 N push and 483 N pull at 0.7 MPa, with a theoretical maximum force of 82 kgf at 1.0 MPa.
It is a JIS-standard profile cylinder with no external rods, making it shorter and more compact than an ISO 15552 cylinder of the same bore. The -S suffix means it has a built-in magnet for CMSE/DMSE switches in the side grooves.
