Airtac JSI Series Standard Cylinder JSI32X280S
The AirTAC Airtac JSI Series Standard Cylinder JSI32X280S is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 280mm 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 JSI32X280S
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 ISO 15552 cylinder of the same 32 mm bore. The extruded hard-anodized aluminum barrel omits external rods to resist wear, while a two-way piston seal retains grease for long, low-friction life. Because the SKU includes the -S magnet, CMSE or DMSE switches drop directly into the side grooves for position sensing.
With a 280 mm stroke and a G1/8 port, it handles light-duty positioning effectively. Plan for about 241 N of real work at 0.5 MPa, which means it lifts about 20 kg vertically with a 2:1 safety margin. The adjustable 20 mm air cushions at both ends decelerate the piston smoothly near stroke end.

Where the Airtac JSI Series Standard Cylinder JSI32X280S Is Used
Small Part Ejection
Pushes lightweight plastic mouldings out of a 32 mm bore press line using 402 N of force over a 280 mm travel distance.
Package Diverting
Actuates a routing gate on a compact packaging conveyor where the shorter JIS profile saves critical clearance.
Clamp Actuation
Secures thin electronic PCBs during ultrasonic welding, applying safe holding pressure without crushing the board.
Is the Airtac JSI Series Standard Cylinder JSI32X280S the Right Cylinder?
For sizing context, this 32 mm bore is the smallest in the JSI family, offering 402 N push at 0.5 MPa. If your application requires more force, stepping up to the 40 mm bore provides 628 N push at the same pressure. Keep in mind that a plain cylinder drifts when air is lost or the valve is centered; the cushion only decelerates the piston and does not act as a lock, so add an external rod lock or pilot-operated check valve if you must hold a load vertically. At 280 mm of travel, use a guide rail to prevent rod bending and premature seal wear from side loads.
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 JSI32X280S FAQ
This 32 mm bore cylinder features a G1/8 port and generates 402 N push / 345 N pull at 0.5 MPa, 563 N push / 483 N pull at 0.7 MPa, and a theoretical maximum of 82 kgf at 1.0 MPa.
Yes, the -S suffix means it has a built-in magnet for CMSE/DMSE switches in the side grooves. It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same bore.
