Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X80-40
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X80-40 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 80mm 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 JSIJ50X80-40
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for applications needing exact end-position tuning. The hard-anodized aluminum extruded body makes it shorter and more compact than a same-bore ISO 15552 unit. It handles about 589 N of real work safely, which translates to lifting roughly 50 kg vertically with a 2:1 margin.
The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, giving a usable forward range of 40 to 80 mm without changing the cylinder itself. This SKU has no magnet and cannot take a sensor; add the -S variant for CMSE/DMSE switches. Air connects via a G1/4 port, and the retract end remains fixed.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X80-40 Is Used
Stroke Tuning for Clamping
Dial in the exact 40 to 80 mm extend reach on-site to clamp varying part widths without swapping actuators.
Variable Length Stops
Adjust the forward stop position on the fly to handle different package lengths on a single line.
Compact Lift Stations
Lift up to 50 kg vertically in tight cells where the shorter JIS profile saves valuable machine space.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X80-40 the Right Cylinder?
Size this 50 mm bore against the 40 mm (628 N push at 0.5 MPa) and 63 mm (1559 N) options to match your force needs. The 40 mm adjustable window is ideal when you need to fine-tune the extend endpoint on-site or want a shared spare across slight stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this is a non-magnet SKU, it cannot take a sensor; choose the -S version if you need CMSE/DMSE position detection. For any stroke over 300 mm, use a guide 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 JSIJ32~50 Adjustable Cylinder JSIJ50X80-40 FAQ
At 0.5 MPa it pushes 982 N and pulls 825 N. At 0.7 MPa it pushes 1374 N and pulls 1154 N. The theoretical maximum force is 200 kgf at 1.0 MPa. The air port size is G1/4.
The nominal 80 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 40 mm, yielding a usable forward range of 40 to 80 mm. The retract end is fixed. This stop sets the end position and is not a load lock.
