Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X175-40
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X175-40 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 175mm 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 JSIJ80X175-40
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings on-site extend-stroke flexibility to heavy automation. The external stop screw provides a 40 mm adjustment window, letting you fine-tune the usable extend stroke anywhere from 135 to 175 mm without swapping the actuator. Its extruded hard-anodized aluminium barrel is noticeably shorter and more compact than a same-bore ISO 15552 unit, while the G3/8 port handles the required air volume.
Built for double-acting single-rod operation, the mechanism shortens the extend end position on-site while the retract end remains fixed. It handles about 1508 N of real work safely, which translates to roughly 128 kg lifted vertically with a 2:1 margin. Note that this specific SKU lacks a magnet and cannot accept CMSE or DMSE sensors; for position feedback you need the -S variant. Furthermore, the adjustable air cushions only decelerate the piston near stroke end, so fit an external rod lock or pilot-operated check valve if you need to hold a load on air loss.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X175-40 Is Used
Press Tooling Alignment
Dial in the exact 135 to 175 mm extend reach on-site to seat parts accurately in forming dies without machining custom spacers.
Variable-Length Diverter
Adjust the extend stop in seconds to deflect different package sizes on a packaging line while maintaining high push force.
Multi-Height Pallet Stop
Fine-tune the end position to act as a physical stop for varying pallet heights, using the 40 mm window to adapt quickly.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X175-40 the Right Cylinder?
When sizing this actuator, the 80 mm bore yields 2513 N push and 2268 N pull at 0.5 MPa, sitting neatly below the 100 mm bore that offers 3927 N push. If your application only needs 1559 N push, stepping down to the 63 mm bore saves space and air. The 40 mm adjustable window is ideal when you need to tune end positions across multiple fixtures or keep one shared spare for slightly different stroke variants. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Because this is a non-magnet SKU, it cannot take position sensors. For any stroke over 300 mm, always use a guide rail to prevent side-load damage to the rod seals.
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 JSIJ80X175-40 FAQ
This 80 mm bore cylinder pushes 2513 N and pulls 2268 N at 0.5 MPa. 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 air port, features a 25 mm rod with an M22x1.5 thread, and has 29 mm adjustable air cushions at both ends.
The nominal 175 mm stroke is the maximum extend length. An external stop screw lets you shorten the extend stroke on-site by up to 40 mm, giving a usable extend range of 135 to 175 mm. The retract end is fixed. This mechanism sets the end position but does not lock the load, so you still need a rod lock or check valve for holding.
