Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X240-100S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X240-100S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 240mm stroke, G1/4 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 JSIJ32~50 Adjustable Cylinder JSIJ50X240-100S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for applications demanding exact end-position tuning on site. An external adjuster allows you to shorten the extend stroke by up to 100 mm, yielding a usable range of 140 to 240 mm while the retract end remains fixed. The extruded hard-anodized aluminium barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 unit. Equipped with a built-in magnet (-S), it accepts CMSE or DMSE reed and electronic switches directly in the side grooves.
Practically, the unit handles a safe working load of about 589 N, which translates to lifting roughly 50 kg vertically with a 2:1 safety margin. Air connects via a G1/4 port, and adjustable air cushions of 20.5 mm at each end absorb impact energy. Remember that the cushion only decelerates the piston near stroke end; a plain cylinder cannot hold a load on air loss, so fit an external rod lock or pilot-operated check valve if you need drift prevention.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X240-100S Is Used
Press Stroke Tuning
Dial in the exact 140 to 240 mm extend position on a light-duty assembly press without swapping cylinders, using the external stop to set the precise crimp depth.
Variable Transfer Diverter
Adjust the extend length on a packaging line diverter gate on-site to accommodate different carton widths, relying on the 982 N push force to move products reliably.
Vertical Lift Positioning
Lift a 50 kg payload vertically and fine-tune the upper stop position safely, knowing the built-in magnet provides exact top-end confirmation for the controls.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X240-100S the Right Cylinder?
When sizing this 50 mm bore, the adjacent 40 mm bore offers 628 N push at 0.5 MPa for lighter duties, while stepping up to a 63 mm bore provides 1559 N for heavier cycles. The 100 mm adjustable window is ideal for sharing one spare cylinder across multiple stroke variants or fine-tuning the extend end position without mechanically remounting the body. The JSIJ series supports Basic, FA, LB, TC, TCM1, and TCM2 mounts. Because the 240 mm stroke exceeds 300 mm, you should guide the load to prevent side-load wear on the rod seals. The included -S magnet enables precise position sensing.

- ✓ 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 JSIJ32~50 Adjustable Cylinder JSIJ50X240-100S FAQ
At 0.5 MPa this 50 mm bore cylinder pushes with 982 N and pulls with 825 N. At 0.7 MPa the push is 1374 N and pull is 1154 N. The theoretical maximum force is 200 kgf at 1.0 MPa. The air port is G1/4, the rod is 20 mm with an M18x1.5 thread, and it features 20.5 mm adjustable air cushions at both ends.
The nominal stroke is 240 mm, which is the maximum extend length. The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, giving a usable extend range of 140 to 240 mm. The retract end is fixed. This stop screw sets the end position and does not lock the load; you need a pilot-operated check valve or external rod lock to hold a load against air loss.
