Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-100S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-100S 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 JSIJ80X275-100S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder keeps your machinery tight. Its extruded hard-anodized aluminium barrel omits external rods, making the body noticeably shorter and more compact than a same-bore ISO 15552 unit. The G3/8 port feeds a 25 mm piston rod that drives a 30-800 mm/s speed range.
The -100 code means an external stop screw lets you trim the extend stroke by up to 100 mm on-site, giving a usable 175-275 mm window while the retract end stays fixed. You can fine-tune the end position without physically swapping the cylinder. It handles about 1508 N of real work safely, which translates to lifting roughly 128 kg vertically. The -S suffix adds a piston magnet for CMSE/DMSE switches that drop directly into the side grooves.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-100S Is Used
Press Stroke Tuning
Dial in the exact 175-275 mm extend reach on a light assembly press without machining new spacers, using the external adjuster to set the precise crush depth.
Variable Length Diverter
Shift packages of different sizes by tweaking the extend stop in seconds, allowing a single diverter arm to handle multiple box lengths on the line.
Adjustable Lift Stop
Control vertical lifting height precisely, safely moving roughly 128 kg loads while relying on the hard-anodized profile body to save vertical space.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-100S the Right Cylinder?
This 80 mm bore sits in the heavy-duty tier, pushing 2513 N at 0.5 MPa. If your load needs less force, step down to the 63 mm bore (1559 N push); if you need more punch, the 100 mm bore delivers 3927 N. The adjustable 175-275 mm extend window is ideal for sharing a single spare across multiple stroke variants or dialing in final positioning on-site. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Because the stroke is 275 mm, add an external guide rail to absorb side loads and prevent rod binding. The included -S magnet supports CMSE/DMSE sensors for position confirmation.
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 JSIJ80X275-100S 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 and a 25 mm rod.
The 275 mm nominal stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 100 mm on-site, giving a usable 175-275 mm range. The retract end is fixed. This mechanism only sets end position; it does not lock the load.
