Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-100
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-100 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 275mm 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 JSIJ80X275-100
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS actuator brings on-site flexibility to demanding pneumatic setups. The hard-anodized aluminum profile barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 cylinder. It handles about 1508 N of real work safely, which translates to roughly 128 kg lifted vertically with a 2:1 margin. Air connects via a G3/8 port, driving a 25 mm piston rod with M22x1.5 end threads.
The -100 code defines an external adjuster window that lets you shorten the extend stroke by up to 100 mm on-site, giving a usable extend range of 175 to 275 mm while the retract end stays fixed. You fine-tune the end position mechanically without swapping the cylinder. This plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor. Note that the adjustable stop sets position only; it is not a load lock, so you need an external rod lock or pilot-operated check valve to hold a load against gravity.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-100 Is Used
Press Stroke Tuning
Dial in the exact 175 to 275 mm extend contact point on a light assembly press without machining new spacers or changing the actuator body.
Variable Length Diverter
Adjust the pusher extension on a packaging line to deflect different carton sizes, using the external stop screw to set the precise reach.
Shared Spare Actuator
Keep one cylinder in maintenance stock and shorten the extend stroke on-site to replace units across multiple machines with similar but varied reach requirements.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-100 the Right Cylinder?
When sizing, the 63 mm bore offers 1559 N push at 0.5 MPa, while the 100 mm bore jumps to 3927 N, so the 80 mm at 2513 N sits perfectly in the middle for medium-heavy duty. The 100 mm adjustable window is ideal when you need to share one spare cylinder across several stroke variants or dial in a precise end stop on the machine floor. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a non-magnet SKU, position sensing is not possible; add the -S suffix for CMSE/DMSE sensor readiness. For this 275 mm stroke, always guide the load to prevent rod side-loading and premature seal wear.
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 JSIJ80X275-100 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, a 25 mm rod with M22x1.5 threads, and has 29 mm adjustable air cushions at both ends.
The nominal 275 mm stroke is the maximum extend length. The external -100 adjuster lets you shorten the extend stroke by up to 100 mm on-site, yielding a usable range of 175 to 275 mm. The retract end remains fixed, and this stop only sets the end position; it does not lock the load.
