Airtac JSI Series Standard Cylinder JSI80X280S
The AirTAC Airtac JSI Series Standard Cylinder JSI80X280S is a genuine double acting JIS-standard air cylinder with a Ø80mm bore and 280mm 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 JSI80X280S
Delivering 2513 N of push force at 0.5 MPa, the AirTAC JSI80X280S is a double-acting JIS-standard profile cylinder built for tight machinery layouts. It is intentionally shorter and more compact than an ISO 15552 cylinder of the same 80 mm bore, saving valuable envelope space without sacrificing power. The extruded hard-anodized aluminum barrel sheds external rods to resist wear, while the heterogeneous two-way piston seal retains grease for a long, low-friction service life. Because this SKU includes the -S magnet, you can drop CMSE or DMSE reed and electronic switches directly into the side grooves for position sensing.
With a 280 mm stroke and G3/8 ports, this model is well-suited for moving substantial masses. 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. The 25 mm hard-chrome piston rod threads M22x1.5, and adjustable 29 mm air cushions at both ends absorb end-of-stroke impact. For jobs requiring opposing or adjustable reach, consider the related JSID double-rod or JSIJ adjustable-stroke variants.

Where the Airtac JSI Series Standard Cylinder JSI80X280S Is Used
Pallet Diversion
Pushes heavy wood or plastic pallets sideways onto adjacent conveyor lanes using 2513 N of thrust at 0.5 MPa.
Vertical Crate Lifting
Elevates component crates weighing up to 128 kg in automated storage systems, relying on the 280 mm stroke to clear shelving.
Press Fixture Clamping
Secures steel stamping blanks inside a press bed, using the compact JIS profile to fit within tight die-clearance dimensions.
Is the Airtac JSI Series Standard Cylinder JSI80X280S the Right Cylinder?
When sizing this 80 mm bore, compare your actual load against the 2513 N push and 2268 N pull figures at 0.5 MPa. If your application is lighter, stepping down to the 63 mm bore yields 1559 N of push force, saving air volume; if you need more muscle, the 100 mm bore jumps to 3927 N. At 280 mm of travel, the extended rod is susceptible to bending under lateral stress, so guide the load externally with linear rails rather than letting the piston rod absorb side loads. Remember that a standard cylinder drifts when air is lost or the valve is centered; the cushions only decelerate the piston near the stroke ends and will not hold a suspended load. For vertical applications, install a pilot-operated check valve or an external rod lock. This -S variant is ready for CMSE/DMSE sensors, whereas a plain SKU without the S cannot accept them.
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 JSI80X280S FAQ
This 80 mm bore cylinder features a G3/8 port and an M22x1.5 rod thread. It generates 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.
The JSI is a JIS-standard profile cylinder that is physically shorter and more compact than an ISO 15552 cylinder of the same 80 mm bore. It uses an extruded hard-anodized aluminum barrel without external rods, making it ideal for space-constrained machinery.
