Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X225-50
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X225-50 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 225mm 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 JSIJ50X225-50
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore pneumatic actuator brings on-site flexibility to fixed-length installations. The extruded hard-anodized aluminium profile barrel keeps the total envelope shorter than a same-bore ISO 15552 cylinder, and the G1/4 air port matches standard JIS manifold layouts.
An external stop screw lets you trim the extend stroke by up to 50 mm, dropping the usable forward travel from the 225 mm maximum down to 175 mm without swapping the cylinder. That mechanism sets the end position but does not lock the load, so a pilot-operated check valve is needed for vertical holding. In practice it handles about 589 N of real work, roughly 50 kg lifted vertically with a 2:1 safety margin.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X225-50 Is Used
Press Fit Tuning
Dial in the exact seating depth of a bearing press by trimming the extend stroke up to 50 mm, ensuring perfect insertion without re-mounting the actuator.
Variable Transfer Stop
Adjust the extended stopper finger position on the fly to accommodate different package lengths on a single sorting line.
Clamp Positioning
Fine-tune the forward clamping point on a machining fixture to compensate for part tolerances, using the full 225 mm travel when needed.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X225-50 the Right Cylinder?
This 50 mm bore sits between the 40 mm class (628 N push at 0.5 MPa) and the 63 mm class (1559 N push), giving you a clear upgrade path if the 40 mm is too weak or the 63 mm is too bulky. The 50 mm adjuster window shines when you need to fine-tune a clamping or pressing end position on the machine, or when you want one shared spare across several stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this SKU lacks the -S magnet, it cannot take a CMSE or DMSE sensor. For a 225 mm stroke, always guide the load to prevent rod side-loading.
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 JSIJ50X225-50 FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa, pushing 1374 N and pulling 1154 N at 0.7 MPa, with a theoretical max of 200 kgf at 1.0 MPa. The air port is G1/4, the rod is 20 mm with an M18x1.5 thread, and it has 20.5 mm adjustable air cushions at both ends.
The 225 mm nominal stroke is the maximum forward travel. The external adjuster lets you shorten the extend stroke on-site by up to 50 mm, giving a usable range of 175 to 225 mm. The retract end is fixed, and the adjuster only sets the end position, it does not hold the load.
