Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X300-20
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X300-20 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 300mm 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 JSIJ50X300-20
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder keeps your machinery compact by being shorter than a same-bore ISO 15552 unit. The hard-anodized aluminium barrel avoids external tie rods for a clean footprint. A G1/4 port feeds the double-acting single-rod piston, which travels a 300 mm maximum stroke at speeds between 30 and 800 mm/s.
The external adjuster lets you shorten the extend stroke on-site by up to 20 mm, yielding a usable range of 280-300 mm without changing the hardware. This on-site tuning handles about 589 N of real work safely, or roughly 50 kg lifted vertically with a 2:1 margin. Note that this specific SKU lacks a magnet and cannot take a CMSE/DMSE sensor; you would need the -S variant for position detection.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X300-20 Is Used
Conveyor Diverter Gate
Fine-tune the 280-300 mm extend reach on-site to push varying carton widths onto parallel lines without swapping the cylinder.
Carton Flap Folder
Adjust the external stop screw by a few millimeters to perfectly fold different box heights on a shared packaging line.
Light Press Assembly
Apply the 982 N push force to seat lightweight components, tweaking the extend end-position to avoid over-travel.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X300-20 the Right Cylinder?
When sizing, the 40 mm bore offers 628 N push at 0.5 MPa for lighter duties, while the 63 mm bore jumps to 1559 N if you need more muscle. The -20 mm adjust window is ideal for sharing one spare across slightly different stroke variants or fine-tuning the end position without machining spacers. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the 300 mm stroke creates leverage, always support the load with an external guide to prevent rod bending under side-load. Remember this plain version cannot host a magnetic switch.
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 JSIJ50X300-20 FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it delivers 1374 N push and 1154 N pull. The theoretical maximum force is 200 kgf at 1.0 MPa. It uses a G1/4 port and a 20 mm rod with an M18x1.5 thread.
The nominal 300 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 20 mm, giving a usable range of 280-300 mm. The retract end is fixed. This mechanism sets the end position and does not lock the load; for load holding on air loss, use an external rod lock or pilot-operated check valve.
