Airtac JSI Series Standard Cylinder JSI80X30S
The AirTAC Airtac JSI Series Standard Cylinder JSI80X30S is a genuine double acting JIS-standard air cylinder with a Ø80mm bore and 30mm stroke, G3/8 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 JSI80X30S
Generating 2513 N of push force at 0.5 MPa, the AirTAC JSI80X30S is a double-acting JIS-standard profile cylinder built for tight machinery. Its extruded hard-anodized aluminum barrel sheds external rods to save space, measuring shorter and more compact than an ISO 15552 cylinder of the same 80 mm bore. The two-way piston seal retains grease for a long, low-friction service life.
This 30 mm stroke unit features a G3/8 port and an M22x1.5 rod thread. Because this SKU includes the -S magnet, it readily accepts CMSE or DMSE electronic switches in the side grooves. Plan for about 1508 N of real work at 0.5 MPa, which translates to lifting roughly 128 kg vertically with a 2:1 safety margin.

Where the Airtac JSI Series Standard Cylinder JSI80X30S Is Used
Pallet Diverters
Pushes heavy wood or plastic pallets sideways across transfer lines using a robust 2513 N push force at 0.5 MPa.
Carton Flap Folders
Folds top flaps on large shipping cartons in packaging facilities, benefiting from the compact profile to fit tight overhead spaces.
Lift Gate Actuation
Raises and lowers auxiliary material handling gates, safely moving loads up to 128 kg vertically with a 2:1 safety margin.
Is the Airtac JSI Series Standard Cylinder JSI80X30S the Right Cylinder?
When sizing this 80 mm bore, dropping down to the 63 mm JSI yields 1559 N of push at 0.5 MPa, while stepping up to the 100 mm bore provides 3927 N. The integrated -S magnet pairs directly with CMSE or DMSE sensors for position detection. Remember that the adjustable 29 mm air cushions only decelerate the piston near stroke ends; they do not act as a brake. If the application requires holding a vertical load during air loss or valve centering, install an external rod lock or pilot-operated check valve to prevent drift.
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 JSI80X30S FAQ
The JSI80X30S delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push and 3175 N pull at 0.7 MPa, with a theoretical maximum of 513 kgf at 1.0 MPa. It uses a G3/8 air port and operates at speeds between 30 and 800 mm/s.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 80 mm bore. The -S suffix means it has a built-in piston magnet, allowing CMSE or DMSE switches to be dropped directly into the side sensor grooves.
