Airtac JSI Series Standard Cylinder JSI32X80S
The AirTAC Airtac JSI Series Standard Cylinder JSI32X80S is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 80mm 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 JSI32X80S
Delivering 402 N of push force at 0.5 MPa, this double-acting 32 mm bore cylinder is built around a JIS-standard profile that is noticeably shorter than an equivalent ISO 15552 unit, saving valuable space on compact machines. 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. Because the -S suffix denotes a built-in piston 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 unit features a 12 mm carbon steel rod with an M10x1.25 thread, adjustable air cushions at both ends, and a G1/8 port. It operates smoothly between 30 and 800 mm/s across a 0.15-1.0 MPa pressure range.

Where the Airtac JSI Series Standard Cylinder JSI32X80S Is Used
Small Part Ejection
Uses the 345 N pull force at 0.5 MPa to reliably strip small plastic moldings from a fixture on an injection molding line.
Package Diverting
Extends 80 mm to push lightweight cardboard cartons from a main belt to a secondary packaging lane.
Clamp Actuation
Secures thin sheet metal brackets in a welding jig, taking advantage of the compact JIS profile to fit tight cell footprints.
Is the Airtac JSI Series Standard Cylinder JSI32X80S the Right Cylinder?
When sizing this 32 mm bore, stepping up to the 40 mm bore increases the 0.5 MPa push force to 628 N, while 32 mm is the smallest available JSI option. The included -S magnet is essential if your control system requires position feedback via CMSE or DMSE sensors. You can mount this cylinder using LB foot, FA/FB flange, CA/CB/CR clevis, TC/TCM1/TCM2 trunnion brackets, or an I/Y/F/U rod knuckle. Note that if air pressure is lost or the valve is centered, the piston will drift; the adjustable cushion only decelerates the rod near the end of stroke and does not act as a locking brake. To hold a load securely, 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 JSI32X80S FAQ
At 0.5 MPa it provides 402 N push and 345 N pull. At 0.7 MPa it provides 563 N push and 483 N pull. The theoretical maximum force is 82 kgf at 1.0 MPa. The air port size is G1/8.
The JSI is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 32 mm bore. It uses an extruded aluminum barrel without external rods, and the -S magnet on this specific model allows CMSE and DMSE sensors to be fitted directly into the side grooves.
