Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-75S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-75S 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 JSIJ40X225-75S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder keeps your machinery compact by being shorter than a same-bore ISO 15552 unit. The hard-anodized aluminum barrel removes external rods for a clean exterior. It handles a safe working load of about 377 N, which means you can vertically lift roughly 32 kg with a 2:1 safety margin. The G1/4 port supplies air efficiently to the 16 mm rod.
The -75 code means an external adjuster can shorten the extend stroke on-site by up to 75 mm, giving a usable range of 150-225 mm while the retract end stays fixed. You can fine-tune the end position without physically swapping the cylinder. The -S suffix adds a built-in piston magnet for CMSE/DMSE switches that drop directly into the side grooves. Remember that the adjustable stop sets position only; it does not hold load on air loss, so use an external rod lock for vertical holding.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-75S Is Used
Adjustable Clamping Stop
Dial in the exact 150-225 mm clamping distance on-site for varying part widths without changing out the entire cylinder assembly.
Transfer Pusher Positioning
Fine-tune the push-off stroke length at the machine side to accommodate different box sizes moving down the line.
Vertical Lift Diverter
Lifts light loads up to 32 kg safely, with the built-in magnet confirming position via CMSE switches for the control system.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-75S the Right Cylinder?
Size this 40 mm bore against the 32 mm option if you need more power, as the 32 mm only provides 402 N of push at 0.5 MPa. If your application requires heavier thrust, step up to the 50 mm bore which outputs 982 N. The adjustable stroke is ideal when you need on-site end-position tuning across shared spare variants, letting one cylinder cover a 150-225 mm range. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The -S magnet enables CMSE/DMSE sensor integration. Because the stroke is 225 mm, ensure you use a guide rail to prevent side-load damage to the 16 mm rod.
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 JSIJ40X225-75S FAQ
At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa it provides 879 N push and 739 N pull. The theoretical maximum force is 128 kgf at 1.0 MPa. This 40 mm bore cylinder uses a G1/4 air port and features a 16 mm piston rod with an M14x1.5 thread.
The external adjuster lets you shorten the extend stroke on-site by up to 75 mm. With a nominal 225 mm maximum stroke, your usable extend range is 150-225 mm while the retract end remains fixed. This allows precise end-position tuning without replacing the cylinder.
