Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X75-75S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X75-75S 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 JSIJ80X75-75S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings on-site extend flexibility to heavy automation. The extruded hard-anodized aluminium barrel omits tie rods, making the body shorter and more compact than a same-bore ISO 15552 unit. A G3/8 port feeds the 25 mm rod, and the -S suffix means a built-in magnet is ready for CMSE/DMSE sensors in the side grooves.
The -75 code defines a 75 mm external adjuster window, letting you trim the usable extend stroke down from the 75 mm maximum to zero without swapping the cylinder. This handles about 1508 N of real work safely, roughly 128 kg lifted vertically with a 2:1 margin. The retract end remains fixed, and the 29 mm adjustable air cushions at each end only decelerate the piston; they do not hold the load on air loss.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X75-75S Is Used
Press Stroke Tuning
Dial in the exact 0-75 mm extend contact point for a light stamping or pressing task without machining a new stop.
Variable Transfer Diverter
Adjust the extend length on a sorting gate to accommodate different package sizes directly on the line.
Shared Spare Cylinder
Keep one 75 mm unit in stock and shorten the extend stroke on-site to cover several shorter fixed-position tasks.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X75-75S the Right Cylinder?
Size this 80 mm bore against the 63 mm class, which offers 1559 N push at 0.5 MPa, or the larger 100 mm class delivering 3927 N. The JSIJ series mounting options cover Basic, FA, LB, TC, TCM1, and TCM2. Because the external adjuster lets you fine-tune the extend end position across a 75 mm window, you can standardise on one spare and trim it on-site for multiple stroke variants. The included -S magnet supports drop-in CMSE/DMSE reed or electronic switches. For any stroke length at or above 300 mm, always use a side-load guide to prevent rod binding.
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 JSIJ80X75-75S 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. It uses a G3/8 port and a 25 mm rod with an M22x1.5 thread.
The 75 mm nominal stroke is the maximum extend length. An external stop screw lets you shorten the extend stroke on-site by up to 75 mm, down to zero. The retract end is fixed. This mechanism sets the end position and is not a load lock.
