Airtac JSI Series Standard Cylinder JSI63X220S
The AirTAC Airtac JSI Series Standard Cylinder JSI63X220S is a genuine double acting JIS-standard air cylinder with a Ø63mm bore and 220mm 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 JSI63X220S
Delivering 1559 N of push force at 0.5 MPa, this double-acting 63 mm bore JIS-standard profile cylinder is purpose-built for mid-weight machinery. Because it uses an extruded hard-anodized aluminum barrel instead of external rods, the overall body is noticeably shorter and more compact than an ISO 15552 cylinder of the same bore. The internal two-way piston seal retains grease exceptionally well, ensuring a long, low-friction service life even at speeds of 30-800 mm/s.
The built-in -S piston magnet lets you drop CMSE or DMSE reed and electronic switches directly into the side grooves for precise end-of-stroke detection. Plan for around 935 N of real work at 0.5 MPa, which translates 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 kinetic energy to protect your tooling.

Where the Airtac JSI Series Standard Cylinder JSI63X220S Is Used
Package Diverting
Pushes medium-weight cartons across sorting lanes at 1559 N, using the 220 mm stroke to clear adjacent conveyor belts safely.
Clamp Actuation
Secures aluminum extrusion profiles during CNC machining, providing reliable 1402 N pull force to hold workpieces against the fixture.
Pallet Stops
Acts as a pneumatic stop gate for loaded pallets, absorbing the impact via its adjustable cushions while the magnet confirms the stop position.
Is the Airtac JSI Series Standard Cylinder JSI63X220S the Right Cylinder?
If 1559 N of push is more than your process requires, dropping down to the 50 mm bore saves space and yields 982 N at 0.5 MPa; conversely, stepping up to the 80 mm bore provides 2513 N for heavier fixtures. For this 220 mm stroke, the side-load risk is moderate, so ensure your mounting—whether an LB foot, FA/FB flange, CA/CB clevis, or TC trunnion—keeps the rod aligned and prevents binding. The included -S magnet pairs perfectly with CMSE/DMSE sensors for position feedback.
Remember that the adjustable air cushion only decelerates the piston near the stroke ends; it does not act as a brake. If your application must hold a vertical load when air pressure drops or the valve centers, you must add an external rod lock or a pilot-operated check valve, as the piston will drift otherwise.
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 JSI63X220S FAQ
This 63 mm bore model uses a G3/8 air port. It delivers 1559 N push and 1402 N pull at 0.5 MPa, 2182 N push and 1962 N pull at 0.7 MPa, with a theoretical maximum of 318 kgf at 1.0 MPa.
The JSI series follows JIS standards and uses an extruded hard-anodized aluminum barrel without external rods, making it significantly shorter and more compact than an ISO 15552 cylinder of the same bore. The -S suffix means it includes a magnet for CMSE/DMSE sensors.
