Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X225-40S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X225-40S 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 JSIJ80X225-40S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder uses an external adjuster to shorten the extend stroke on site by up to 40 mm. The nominal 225 mm stroke remains the maximum, yielding a usable extend range of 185-225 mm, while the retract end stays fixed. Its extruded hard-anodized aluminum barrel omits tie rods entirely, making the body shorter and more compact than a same-bore ISO 15552 unit. The G3/8 port feeds the 29 mm adjustable air cushions at both ends.
A built-in magnet equips this -S variant for CMSE/DMSE sensors that drop directly into the side grooves. In practical terms the bore handles about 1508 N of safe working load, which translates to lifting roughly 128 kg vertically with a 2:1 margin. Remember the cushion only decelerates the piston near the end of travel; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended load.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X225-40S Is Used
Press Fit Tuning
Dial in the exact 200 mm extend reach for seating bearings without remounting the entire actuator.
Variable Transfer Stop
Adjust the 225 mm extend stop on the fly to handle different pallet widths on a single line.
Vertical Lift Dampening
Lift 128 kg loads using the 29 mm cushions to decelerate smoothly at the top of the 185 mm stroke.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X225-40S the Right Cylinder?
When sizing this unit, the 63 mm bore offers 1559 N push at 0.5 MPa for lighter jobs, while the 100 mm bore jumps to 3927 N if you need substantially more thrust. The 40 mm adjustable window is ideal for fine-tuning the extend end position on site without swapping the cylinder, letting you standardize one spare across several stroke variants. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Because this is an -S model, it arrives ready for CMSE/DMSE reed or electronic switches. For any stroke at or over 300 mm, always use a guide rail to prevent side-load damage to the rod seal.
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 JSIJ80X225-40S FAQ
