Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X75-40
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X75-40 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 JSIJ80X75-40
Delivering 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 omits tie rods, making the overall body shorter and more compact than a same-bore ISO 15552 unit. It handles about 1508 N of real work safely, which translates to lifting roughly 128 kg vertically with a 2:1 margin.
An external stop screw lets you shorten the extend stroke on-site by up to 40 mm, giving a usable forward range of 35-75 mm while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder. Pneumatically it runs through a G3/8 port, with 29 mm adjustable air cushions at both ends to decelerate the load smoothly.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X75-40 Is Used
Press Fit Tuning
Dial in the exact insertion depth of a bearing press by trimming the extend stroke up to 40 mm on-site, avoiding mechanical spacer changes.
Variable Transfer Stop
Act as an adjustable lane diverter on a packaging line, fine-tuning the stop position for different carton lengths without changing cylinders.
Pallet Positioning
Push heavy pallets into a wrapping station, using the 2513 N push force and the external adjuster to set the precise end location.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X75-40 the Right Cylinder?
Stepping down to a 63 mm bore drops the 0.5 MPa push force to 1559 N, whereas a 100 mm bore raises it to 3927 N for heavier demands. The -40 mm adjuster window is ideal when you need to share one spare cylinder across several stroke variants or trim the end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a non-magnetized SKU, it cannot accept a CMSE or DMSE sensor; order the -S variant if you need position detection. For any stroke over 300 mm, always 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 JSIJ80X75-40 FAQ
At 0.5 MPa it provides 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. The air port size is G3/8.
The nominal 75 mm extend stroke is the maximum. An external stop screw lets you shorten the forward stroke by up to 40 mm on-site, yielding a usable extend range of 35-75 mm. The retract end is fixed, and this mechanism only sets the end position—it is not a load lock.
