Airtac JSI Series Standard Cylinder JSI32X70S
The AirTAC Airtac JSI Series Standard Cylinder JSI32X70S is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 70mm 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 JSI32X70S
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 equivalent ISO 15552 unit of the same 32 mm 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 includes the -S magnet, you can drop CMSE or DMSE reed and electronic switches directly into the side grooves for position sensing.
Air connects via a G1/8 port, driving the 12 mm carbon steel rod at speeds of 30-800 mm/s. Plan for about 241 N of real work at 0.5 MPa, which translates to lifting roughly 20 kg vertically with a 2:1 safety margin. The adjustable 20 mm air cushions at both ends absorb impact energy near the stroke limits.

Where the Airtac JSI Series Standard Cylinder JSI32X70S Is Used
Small Part Ejection
Pushes lightweight plastic moldings out of an injection press using a safe 241 N working load.
Package Diverting
Actuates a deflector gate on a packaging line to sort small cartons at up to 800 mm/s.
Clamp Actuation
Secures electronic PCBs during soldering, using the built-in magnet to confirm clamp position.
Is the Airtac JSI Series Standard Cylinder JSI32X70S the Right Cylinder?
If you need slightly less force, there is no smaller JSI bore available, so this 32 mm model is the floor of the range; stepping up to the JSI40X70S raises the 0.5 MPa push force to 628 N. Remember that a standard pneumatic cylinder drifts when air is lost or the valve is centered, as the cushions only decelerate the piston near the end of travel rather than locking it. For suspended loads that must be held securely, add an external rod lock or a pilot-operated check valve. At a 70 mm stroke, side-load stress on the rod is minimal, so standard LB, FA, or TC mounting will perform reliably.
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 JSI32X70S 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 is 82 kgf at 1.0 MPa, and the air port is G1/8.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 32 mm bore, saving machine space while retaining full double-acting functionality.
