Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-30S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-30S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 450mm 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 JSIJ40X450-30S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore pneumatic actuator brings on-site flexibility to demanding setups. The hard-anodized aluminum profile barrel keeps the overall body more compact than a same-bore ISO 15552 unit, while the G1/4 port matches the standard JIS sizing.
A built-in magnet (-S) allows CMSE/DMSE switches to drop directly into the side grooves for precise position detection. The external adjuster lets you shorten the extend stroke by up to 30 mm on site, meaning the usable extend range is 420-450 mm without swapping the cylinder. It handles about 377 N of real work safely, which translates to lifting roughly 32 kg vertically with a 2:1 margin.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-30S Is Used
Conveyor Diverter Tuning
Fine-tune the 450 mm extend stop by up to 30 mm on site to perfectly align a diverter gate without machining new mounts.
Variable Carton Push-off
Adjust the extend end position on the fly to handle different carton depths on a packaging line using the G1/4 ported body.
Pallet Stop Calibration
Dial in the exact stopping point for mixed pallet sizes, relying on the 628 N push force to halt loads securely.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-30S the Right Cylinder?
When sizing, the 32 mm bore offers 402 N push at 0.5 MPa for lighter duties, whereas the 50 mm bore steps up to 982 N if you need more thrust. The JSIJ series supports Basic, FA, LB, TC, TCM1, and TCM2 mounts. The -30 mm adjustable window is ideal for fine-tuning end positions across multiple stroke variants or sharing a spare. Because the stroke is 450 mm, always use external guides to prevent rod bending and side loads. The -S variant includes the magnet for sensors; a no-S SKU cannot take one.
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 JSIJ40X450-30S FAQ
This 40 mm bore cylinder pushes 628 N and pulls 528 N at 0.5 MPa, and pushes 879 N / pulls 739 N at 0.7 MPa. The theoretical maximum force is 128 kgf at 1.0 MPa. It uses a G1/4 air port.
The nominal 450 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 30 mm on site, giving a usable extend range of 420-450 mm. The retract end is fixed, and this stop only sets position—it is not a load lock.
