Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X275-75
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X275-75 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm 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 JSIJ63X275-75
The hard-anodized aluminum barrel omits tie rods entirely, making the overall body shorter and more compact than a same-bore ISO 15552 unit.
The -75 code defines an external adjuster window that shortens the extend stroke by up to 75 mm on-site, giving a usable forward range of 200 to 275 mm while the retract end remains fixed. You can fine-tune the end position without swapping the cylinder. Air connects via a G3/8 port, and adjustable air cushions of 29 mm decelerate the piston at both ends. This plain SKU lacks a magnet and cannot take a sensor; order the -S version for CMSE or DMSE switches.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|

JSIJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X275-75 Is Used
Stroke Tuning for Tooling Stops
Dial in the exact extend position within the 200 to 275 mm window on-site to accommodate varying workpiece heights without machining new hard stops.
Shared Spare for Palletizers
Keep one cylinder as a plant-wide replacement for 63 mm bore machines, trimming the extend stroke as needed to match the original unit's exact travel.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X275-75 the Right Cylinder?
The adjustable stroke is ideal for sharing one spare across multiple stroke variants or dialing in a precise end position during machine commissioning. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because the 275 mm stroke exceeds 300 mm only slightly, guide any side loads carefully to prevent rod bending. Note that this non-magnetic SKU cannot support position sensing.
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 JSIJ63X275-75 FAQ
At 0.5 MPa it pushes 1559 N and pulls 1402 N. At 0.7 MPa it pushes 2182 N and pulls 1962 N. The theoretical maximum force is 318 kgf at 1.0 MPa. The air port size is G3/8.
The 275 mm nominal stroke is the maximum forward travel. The external adjuster lets you shorten the extend stroke on-site by up to 75 mm, yielding a usable range of 200 to 275 mm. The retract end is fixed, and the adjuster only sets the end position—it does not lock the load.
