Airtac JSI Series Standard Cylinder JSI63X300FA
The AirTAC Airtac JSI Series Standard Cylinder JSI63X300FA is a genuine double acting JIS-standard air cylinder with a Ø63mm bore and 300mm 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 JSI63X300FA
Generating 1559 N of push force at 0.5 MPa, this double-acting JIS-standard profile cylinder is purpose-built for tight machinery envelopes. It is notably shorter and more compact than an ISO 15552 cylinder of the same 63 mm bore, saving valuable real estate without sacrificing power.
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 specific SKU lacks the -S magnet, it cannot accept CMSE or DMSE position switches. For practical sizing, plan for roughly 935 N of real work at 0.5 MPa, which translates to lifting about 79 kg vertically with a 2:1 safety margin. Air enters via G3/8 ports, and the FA flange mount secures the body firmly.

Where the Airtac JSI Series Standard Cylinder JSI63X300FA Is Used
Automated Press Ejection
Delivers 1559 N at 0.5 MPa to push formed metal parts out of a hydraulic press bed, using the 300 mm stroke to clear the tooling area completely.
Pallet Diversion Arm
Mounts via the FA flange to drive a 300 mm sweeping arm that redirects heavy product pallets onto a secondary packaging line without stalling.
Vertical Gate Actuation
Raises and lowers a 75 kg security gate on a storage retrieval unit, operating comfortably within the 79 kg vertical lift capacity at 0.5 MPa.
Is the Airtac JSI Series Standard Cylinder JSI63X300FA the Right Cylinder?
When sizing this actuator, consider the adjacent bores: a 50 mm bore yields 982 N of push at 0.5 MPa, while stepping up to an 80 mm bore provides 2513 N. If your machine requires position feedback, you must select the -S magnet variant to enable CMSE or DMSE sensors, as this base SKU cannot take a switch. Because the stroke is 300 mm, support the rod against side loads with an external guide to prevent bending and premature seal wear. Note that air loss will cause the piston to drift; the adjustable 29 mm cushions only decelerate the stroke end, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended load.
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 JSI63X300FA FAQ
This 63 mm bore cylinder delivers 1559 N push and 1402 N pull at 0.5 MPa, increasing to 2182 N push and 1962 N pull at 0.7 MPa, with a theoretical maximum of 318 kgf at 1.0 MPa. It features a 20 mm rod, M18x1.5 rod thread, G3/8 ports, and adjustable 29 mm air cushions at both ends.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSE or DMSE switches. You must order the -S variant if your application requires position sensing.
