Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X100-50S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X100-50S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 100mm 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 JSIJ80X100-50S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore model brings substantial power to your fixture. The hard-anodized aluminum profile barrel keeps the body shorter than a same-bore ISO 15552 unit, saving valuable machine space. A built-in magnet (-S) lets you drop CMSE or DMSE reed and electronic switches straight into the side grooves for precise position detection.
The external adjuster allows you to shorten the extend stroke on-site by up to 50 mm, giving a usable range of 50-100 mm without swapping the cylinder. It handles about 1508 N of real work safely, which translates to roughly 128 kg lifted vertically. Air connects via a G3/8 port, and the adjustable air cushions provide 29 mm of deceleration at each end. Remember that the cushion only softens the stop; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve to hold a load.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X100-50S Is Used
Press Fit Tuning
Dial in the exact 50-100 mm extend depth for seating bearings without machining custom spacers or changing the actuator body.
Variable Transfer Stops
Adjust the retract stopper height on-site by up to 50 mm to handle different package sizes on a single sorting line.
Pallet Lift Alignment
Fine-tune the lift end position to match pallet deflection, using the G3/8 port and 2513 N capacity to raise heavy loads.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X100-50S the Right Cylinder?
When sizing this unit, the neighboring 63 mm bore offers 1559 N push at 0.5 MPa for lighter fixtures, while the 100 mm bore steps up to 3927 N for heavier demands. The adjustable stroke is perfect for tuning end positions on-site or sharing a single spare across multiple stroke variants. You can mount it using FA, LB, TC, TCM1, or TCM2 brackets. The -S magnet supports CMSE/DMSE sensors for end-position confirmation. Because the nominal stroke is 100 mm, side-load risks are low, but always guide the tooling for any stroke reaching 300 mm or more.
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 JSIJ80X100-50S FAQ
At 0.5 MPa it pushes 2513 N and pulls 2268 N. At 0.7 MPa it pushes 3518 N and pulls 3175 N. The theoretical maximum force is 513 kgf at 1.0 MPa.
The nominal 100 mm extend stroke is the maximum. An external stop screw lets you shorten the extend end position by up to 50 mm on-site, yielding a usable 50-100 mm range. The retract end remains fixed.
