Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X225-20
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X225-20 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 225mm 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 JSIJ63~80 Adjustable Cylinder JSIJ80X225-20
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder keeps your footprint tight. The extruded hard-anodized aluminium barrel makes it shorter and more compact than a same-bore ISO 15552 unit, with no exposed tie rods.
The external -20 adjuster lets you fine-tune the extend stroke down to 205 mm on-site without swapping the cylinder. It handles about 1508 N of real work, roughly 128 kg lifted vertically. Piped via a G3/8 port, it features 29 mm adjustable air cushions at both ends.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X225-20 Is Used
Press Fit Tuning
Dial in the exact 205 to 225 mm extend position on-site to seat bearings without bottoming out the tooling.
Divert Arm Adjustment
Shift the extend stop by up to 20 mm to change the push distance of packages between lanes.
Pallet Stopper Gate
Set the precise pallet contact height on-site, using the 2513 N push force to halt heavy loads securely.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X225-20 the Right Cylinder?
Size this 80 mm bore against the 63 mm option, which gives 1559 N push at 0.5 MPa, or the larger 100 mm bore, which provides 3927 N. The adjustable stroke is ideal when you need to tune the extend end position on the fly or want a single spare for multiple stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a non-magnet SKU, it cannot take a CMSE or DMSE sensor. For this 225 mm stroke, use a guide rail to prevent side-load damage.
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 JSIJ63~80 Adjustable Cylinder JSIJ80X225-20 FAQ
At 0.5 MPa it delivers 2513 N push and 2268 N pull. At 0.7 MPa it provides 3518 N push and 3175 N pull. The theoretical maximum force is 513 kgf at 1.0 MPa. This 80 mm bore unit uses a G3/8 air port and a 25 mm piston rod.
The nominal 225 mm extend stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 20 mm on-site, giving a usable range of 205 to 225 mm. The retract end is fixed. This stop only sets the end position; it does not lock the load.
