Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X75-30
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X75-30 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 75mm 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 JSIJ40X75-30
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder saves machine space by being shorter than a same-bore ISO 15552 unit. The hard-anodized aluminum barrel keeps the build clean without external rods. It handles about 377 N of real work safely, which translates to lifting roughly 32 kg vertically with a 2:1 margin.
An external adjuster lets you shorten the extend stroke on site by up to 30 mm, giving a usable forward range of 45 to 75 mm while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder. Air connects via a G1/4 port. Note this SKU lacks a magnet and cannot take CMSE/DMSE sensors.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X75-30 Is Used
Clamp Stroke Tuning
Dial in the exact 45 to 75 mm forward clamp position on-site using the external adjuster to accommodate varying part thicknesses without changing cylinders.
Transfer Stopper
Act as a height-specific flow stopper where the 30 mm extend shortening window perfectly sets the stopping distance for delicate product handling.
Compact Tooling Push
Fit into tight automation cells where the shorter JIS profile body provides 628 N of push force without the length penalty of an ISO 15552 cylinder.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X75-30 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 jumps to 982 N. The 30 mm adjuster window is ideal for sharing one spare cylinder across multiple stroke variants or dialing in final end positions on-site. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this plain SKU has no magnet, you cannot fit CMSE/DMSE switches; choose an -S variant if you need sensing. For any stroke over 300 mm, always guide the load 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 JSIJ40X75-30 FAQ
At 0.5 MPa it pushes 628 N and pulls 528 N. At 0.7 MPa it pushes 879 N and pulls 739 N. The theoretical maximum force is 128 kgf at 1.0 MPa. It uses a G1/4 port and a 16 mm rod.
The nominal 75 mm extend stroke is the maximum. An external stop screw lets you shorten the forward stroke by up to 30 mm on site, yielding a usable extend range of 45 to 75 mm. The retract end remains fixed. This mechanism sets the end position and does not lock the load; use an external rod lock or pilot-operated check valve to hold a load against air loss.
