Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-100
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-100 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm 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 JSIJ40X225-100
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder is built for applications needing flexible end-positioning. The extruded hard-anodized aluminium barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 unit. It handles a safe working load of about 377 N, which translates to lifting roughly 32 kg vertically with a 2:1 margin.
The JSIJ40X225-100 uses a G1/4 port and an external stop screw to shorten the extend stroke on site by up to 100 mm. You can tune the usable extend travel anywhere from 125 mm up to the 225 mm maximum without swapping the cylinder, while the retract end remains fixed. This stop screw sets the end position and decelerates the load via the 20.5 mm adjustable air cushions, but it does not lock the load on air loss. Because this SKU lacks a magnet, it cannot take a CMSE or DMSE sensor.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-100 Is Used
Adjustable Clamping Press
Dial in the exact 125 to 225 mm extend reach on site to clamp varying part heights without changing out the entire cylinder.
Variable Transfer Stopper
Use the external adjuster to fine-tune the end position on a conveyor line, accommodating different package widths on the fly.
Compact Sorting Diverter
Fit a shorter JIS-profile diverter into tight machinery spaces while retaining the ability to shorten the stroke by 100 mm if needed.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-100 the Right Cylinder?
Size this 40 mm bore against its neighbours: a 32 mm bore gives 402 N push at 0.5 MPa, while a 50 mm bore offers 982 N. The adjustable -100 mm window is ideal when you need to fine-tune the extend end position on site or want a shared spare across stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. For the 225 mm stroke, ensure adequate side-load guidance to prevent rod damage. To hold a load securely on air loss, add an external rod lock or pilot-operated check valve, as the cushion only decelerates.
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 JSIJ40X225-100 FAQ
This 40 mm bore cylinder uses a G1/4 port and generates 628 N push / 528 N pull at 0.5 MPa, and 879 N push / 739 N pull at 0.7 MPa. The theoretical maximum force is 128 kgf at 1.0 MPa.
The nominal 225 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke on site by up to 100 mm, giving a usable extend range of 125 to 225 mm. The retract end is fixed, and the adjuster sets position but does not lock the load.
