Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X75-50
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X75-50 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 75mm 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 JSIJ80X75-50
Generating 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder is built for heavy-duty positioning. The extruded hard-anodized aluminum barrel makes it shorter and more compact than a same-bore ISO 15552 unit, saving valuable machine space. It handles about 1508 N of real work safely, which translates to roughly 128 kg lifted vertically with a 2:1 margin.
The external adjuster lets you shorten the extend stroke on-site by up to 50 mm, giving a usable extend range of 25 to 75 mm while the retract end stays fixed. You can fine-tune the end position without physically swapping the cylinder. Pneumatically it uses a G3/8 port and adjustable 29 mm air cushions at both ends. Note this plain SKU lacks a magnet and cannot take CMSE/DMSE sensors, and the cushion only decelerates the load rather than holding it.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X75-50 Is Used
Press Stroke Calibration
Dial in the exact 25 to 75 mm extend reach on-site to set precise material contact depth without machining custom spacers.
Heavy Vertical Dampening
Leverage the 29 mm adjustable cushions to safely decelerate a 128 kg vertical load before it hits the base stop.
Multi-Tool Pin Puller
Standardize one 80 mm bore body across several stations and use the external screw to tune the retract clearance per fixture.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X75-50 the Right Cylinder?
When sizing this 80 mm bore, the neighbouring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore steps up to 3927 N, so choose based on your exact force margin. The 50 mm adjustable window is ideal for sharing a single spare cylinder across machines that need slightly different extend endpoints. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this SKU has no -S magnet, position sensing is impossible without switching to the -S variant. For any stroke over 300 mm, always use a guide rail to prevent side-load damage to the rod.
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 JSIJ80X75-50 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 75 mm extend stroke is the maximum. The external adjuster lets you shorten that extend travel by up to 50 mm on-site, yielding a usable range of 25 to 75 mm. The retract end is fixed, and this stop only sets position rather than locking the load.
