Airtac JSI Series Standard Cylinder JSI32X125
The AirTAC Airtac JSI Series Standard Cylinder JSI32X125 is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 125mm 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 JSI32X125
Delivering 402 N of push force at 0.5 MPa, this double-acting 32 mm bore cylinder is engineered for tight machinery layouts. As a JIS-standard profile unit, it occupies a shorter envelope than an ISO 15552 cylinder 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.
Because this SKU lacks the -S magnet, it cannot host CMSE or DMSE position switches. For sizing real jobs, plan for about 241 N of actual work at 0.5 MPa, which equates to lifting roughly 20 kg vertically with a 2:1 safety margin. The unit features a G1/8 port, an M10x1.25 rod thread, and adjustable air cushions at both ends.

Where the Airtac JSI Series Standard Cylinder JSI32X125 Is Used
Small Part Ejection
Uses the 345 N pull force at 0.5 MPa to reliably strip small molded plastic components from a die on a 125 mm stroke.
Package Diverting
Pushes lightweight cardboard cartons on a packaging line, where the compact profile saves valuable machine footprint.
Clamp Actuation
Secures thin sheet metal in a small welding jig, applying a safe working load of about 241 N without over-stressing the part.
Is the Airtac JSI Series Standard Cylinder JSI32X125 the Right Cylinder?
When sizing this 32 mm bore, stepping up to the 40 mm bore raises the 0.5 MPa push force to 628 N, while 32 mm is the smallest available JSI option. This 125 mm stroke falls well within the 1000 mm maximum, operating at 30-800 mm/s. Since this specific model has no -S suffix, it cannot accept magnetic sensors; if position detection is required, select the -S variant for CMSE or DMSE switches.
Remember that a standard pneumatic cylinder drifts when air is lost or the valve is centered, as the end cushions only decelerate the piston near stroke limits rather than locking it. To sustain a suspended load, install an external rod lock or a pilot-operated check valve. For mounting, choose from LB foot, FA/FB flange, CA/CB/CR clevis, TC/TCM1/TCM2 trunnion, or I/Y/F/U rod knuckles.
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 JSI32X125 FAQ
The JSI32X125 delivers a push force of 402 N and a pull force of 345 N at 0.5 MPa. At 0.7 MPa, the push is 563 N and the pull is 483 N. The theoretical maximum force is 82 kgf at 1.0 MPa. It uses a G1/8 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 32 mm bore. The adjustable air cushions only decelerate the piston near stroke ends and do not act as a brake; the piston will drift if air is lost, so an external rod lock is needed to hold a load.
