Airtac JSI Series Standard Cylinder JSI32X550S
The AirTAC Airtac JSI Series Standard Cylinder JSI32X550S is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 550mm 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 JSI32X550S
Delivering 402 N of push force at 0.5 MPa, this double-acting 32 mm bore cylinder saves valuable machine space by being shorter and more compact than an ISO 15552 unit of the same bore. The extruded hard-anodized aluminum barrel omits external rods to resist wear, while the two-way piston seal retains grease for a long, low-friction service life. A G1/8 port supplies air, and the 550 mm stroke operates at 30-800 mm/s.
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. Plan for roughly 241 N of actual work at 0.5 MPa, which translates to lifting 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 JSI32X550S Is Used
Small Part Diversion
Pushes lightweight packages on a packaging conveyor over a 550 mm reach, utilizing the 402 N push force to deflect items into sorting lanes.
Print Head Positioning
Shifts an inkjet print head assembly along a 550 mm axis, where the compact JIS profile minimizes the machine footprint and the -S magnet confirms stroke ends.
Tray Push-Off
Acts as a tray push-off in a palletizer, moving empty pallets horizontally with a safe working load of 241 N at 0.5 MPa.
Is the Airtac JSI Series Standard Cylinder JSI32X550S the Right Cylinder?
When sizing this 32 mm bore, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa, while the 32 mm is the smallest available JSI option. The built-in -S magnet pairs perfectly with CMSE or DMSE sensors. Since the 550 mm stroke exceeds 300 mm, carefully manage side loads to prevent rod bending and use external guide rails to support the payload.
Note that a standard pneumatic cylinder drifts when air is lost or the valve is centered. The end cushions only slow the piston near stroke limits and do not act as a brake. To hold a load securely in place, install 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 JSI32X550S FAQ
This 32 mm bore cylinder features a G1/8 port and an M10x1.25 rod thread. The thrust output is 402 N push and 345 N pull at 0.5 MPa, increasing to 563 N push and 483 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
The JSI is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same bore, saving space on tight machines. It uses an extruded hard-anodized aluminum barrel without external rods. The -S magnet on this model allows CMSE and DMSE sensors to be fitted directly into the side grooves.
