Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-100
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-100 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 JSIJ40X450-100
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder manages about 377 N of safe working load and lifts roughly 32 kg vertically with a 2:1 margin. The hard-anodized aluminium barrel keeps the overall build shorter than a same-bore ISO 15552 unit, while the G1/4 port feeds the 16 mm rod.
An external adjuster lets you trim the extend stroke on-site by up to 100 mm, dropping the usable forward travel from the 450 mm maximum down to 350 mm without swapping the cylinder. Because this SKU lacks a magnet, it cannot take a CMSE or DMSE sensor. Note that the adjustable stop only sets the end position; it does not lock the load, so fit an external rod lock or pilot-operated check valve if you need to hold against gravity.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-100 Is Used
Transfer Push-Off Tuning
Dial in the exact push-off distance on a moving conveyor by trimming the extend stroke up to 100 mm on-site without machining new hardstops.
Variable Carton Flap Fold
Adapt to changing carton depths on a packaging line by adjusting the forward reach from the 450 mm maximum to suit each format.
Diverter Arm Positioning
Set the precise extend endpoint for a sorting diverter arm on-site, ensuring packages deflect cleanly without needing cylinder swaps.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-100 the Right Cylinder?
If 628 N of push at 0.5 MPa is too light, step up to the 50 mm bore for 982 N; if that is excessive, drop to the 32 mm bore for 402 N. The 100 mm adjuster window shines when you need to fine-tune end positions on-site or standardise one spare across several stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. As this is a no-magnet SKU, you cannot add a CMSE or DMSE switch; choose an -S variant if you need sensing. With a 450 mm stroke, always support the load with external guides to prevent rod bending and premature seal wear.
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 JSIJ40X450-100 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. The air port is G1/4.
The nominal 450 mm stroke is the maximum forward travel. The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, giving a usable extend range of 350-450 mm. The retract end is fixed. This mechanism sets the end position and does not hold the load.
