Airtac JSI Series Standard Cylinder JSI63X30
The AirTAC Airtac JSI Series Standard Cylinder JSI63X30 is a genuine double acting JIS-standard air cylinder with a Ø63mm bore and 30mm stroke, G3/8 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 JSI63X30
Delivering 1559 N of push force at 0.5 MPa, this double-acting 63 mm bore cylinder provides robust actuation in a tight 30 mm stroke package. As a JIS-standard profile unit, it occupies less envelope length than a same-bore ISO 15552 cylinder, saving valuable space on machinery. The extruded hard-anodized aluminum barrel omits external rods to resist wear, while the two-way piston seal retains grease for long, low-friction life.
Because this specific SKU lacks the -S magnet, it cannot host CMSE or DMSE position switches without modification. In practical terms, plan for about 935 N of real work at 0.5 MPa (60 percent of the rated push), which equates to lifting roughly 79 kg vertically with a 2:1 safety margin. Air enters via the G3/8 port, and adjustable 29 mm cushions at both ends absorb end-of-stroke impact.

Where the Airtac JSI Series Standard Cylinder JSI63X30 Is Used
Short-Stroke Clamping
Ideal for securing heavy steel plates in a machining center, using its 1559 N push force to lock parts firmly against a stop in a tight 30 mm travel.
Package Ejection
Mounts inline on a packaging line to push cartons onto a secondary belt, where the compact JIS profile avoids interfering with adjacent moving belts.
Press Ejection
Fits neatly into a stamping press to knock out small metal blanks, leveraging the hard-anodized barrel to withstand repeated high-frequency impacts.
Is the Airtac JSI Series Standard Cylinder JSI63X30 the Right Cylinder?
When sizing this 63 mm bore actuator, compare its 1559 N push at 0.5 MPa against the neighboring options: a 50 mm bore yields 982 N, while an 80 mm bore provides 2513 N. Choose this 30 mm stroke variant for short clamping or ejecting duties where full extension is minimal. For any application requiring the piston to stay put after a loss of air pressure or valve centering, remember this standard cylinder will drift; the air cushions only decelerate the stroke and do not act as a brake. Install an external rod lock or pilot-operated check valve to hold suspended loads safely.
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 JSI63X30 FAQ
At 0.5 MPa it provides 1559 N push and 1402 N pull. At 0.7 MPa it delivers 2182 N push and 1962 N pull. The theoretical maximum force is 318 kgf at 1.0 MPa. The air port size is G3/8.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSE or DMSE magnetic switches. You would need the -S variant to use sensors in the side grooves.
