Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X75-50S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X75-50S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 75mm 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 JSIJ80X75-50S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder saves space by being shorter than a same-bore ISO 15552 unit. The hard-anodized aluminum barrel keeps the assembly light while housing a 25 mm rod, M22x1.5 thread, and 29 mm adjustable air cushions at both ends. A built-in magnet (-S) allows CMSE or DMSE sensors to drop directly into the side grooves for precise position detection.
The -50 code means an external adjuster can shorten the extend stroke on-site by up to 50 mm, giving a usable forward range of 25 to 75 mm without changing the cylinder itself. This on-site tuning is ideal for dialing in exact end positions, and the G3/8 port feeds the chamber efficiently. In practical terms it handles about 1508 N of real work safely, which translates to lifting roughly 128 kg vertically with a 2:1 margin. Note that the cushion only decelerates the load; use an external rod lock or pilot-operated check valve if you need to hold position on air loss.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X75-50S Is Used
Press Fit Tuning
Dial in the exact seating depth of a bearing press on-site using the 50 mm adjuster window, avoiding cylinder swaps when prototypes change.
Variable Diverter Arm
Adjust the extend reach of a sorting gate by up to 50 mm to handle different package sizes without repositioning the entire mount.
Pallet Stop Positioning
Fine-tune the stopping point for incoming pallets on a conveyor line, using the sensor-ready magnet to confirm the retracted home position.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X75-50S the Right Cylinder?
When sizing this 80 mm bore, stepping down to a 63 mm bore yields 1559 N push at 0.5 MPa, while stepping up to a 100 mm bore provides 3927 N. The adjustable stroke shines when you need to fine-tune the extend end position on the machine or want a single shared spare across slight stroke variants. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. The -S magnet equips the cylinder for CMSE/DMSE switches. Because the stroke here is under 300 mm, side-load risks are minimal, but always guide the load for any stroke reaching 300 mm or more.
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 JSIJ80X75-50S 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 is 513 kgf at 1.0 MPa. It uses a G3/8 port.
The nominal 75 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 50 mm, giving a usable range of 25 to 75 mm. The retract end remains fixed.
