Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X125-100
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X125-100 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 125mm 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 JSIJ80X125-100
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings substantial power to compact assemblies. Its extruded hard-anodized aluminium barrel omits external rods, making the body noticeably shorter than a same-bore ISO 15552 unit. The G3/8 port feeds the 25 mm piston rod to deliver strong extension thrust.
A 100 mm external stop screw window lets you trim the extend stroke down from the 125 mm maximum to a 25 mm minimum directly on-site. This allows fine end-position tuning without swapping the cylinder, handling about 1508 N of real work or roughly 128 kg lifted vertically. The retract end remains fixed, and the adjustable air cushions provide 29 mm of deceleration at each end.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X125-100 Is Used
Variable Clamp Pressing
Adjusts the extend stroke on-site to press parts of varying heights without changing tooling fixtures.
Multi-Position Diverter
Tunes the push distance on a sorting line to deflect different package sizes accurately.
Adjustable Stop Gate
Sets precise material stop positions on a heavy roller bed by trimming the extend stroke within the 100 mm window.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X125-100 the Right Cylinder?
When sizing, the neighbouring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore steps up to 3927 N. This 80 mm model fits neatly in the middle for medium-heavy handling. The 100 mm adjuster window is ideal when you need a shared spare across multiple stroke variants or precise on-site end-position tuning. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch. 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 JSIJ80X125-100 FAQ
It provides 2513 N push and 2268 N pull at 0.5 MPa, and 3518 N push and 3175 N pull at 0.7 MPa. The theoretical maximum force is 513 kgf at 1.0 MPa.
The nominal 125 mm extend stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 100 mm on-site, giving a usable extend range of 25-125 mm. The retract end is fixed.
