Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X700-100
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X700-100 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 700mm 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 JSIJ40X700-100
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder is built for applications needing exact end-position flexibility. The hard-anodized aluminum barrel omits tie rods entirely, making the unit significantly shorter and more compact than a same-bore ISO 15552 cylinder. It handles about 377 N of real work safely, which translates to roughly 32 kg lifted vertically with a 2:1 margin.
The -100 code defines an external adjuster window that shortens the extend stroke on site by up to 100 mm, giving a usable extend range of 600 to 700 mm while the retract end remains fixed. You can fine-tune the stopping point without physically swapping the cylinder. This specific SKU lacks the -S magnet option and therefore cannot accept CMSE or DMSE sensors. Pneumatic connections use a G1/4 port, and adjustable air cushions of 20.5 mm decelerate the piston at both ends.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X700-100 Is Used
Conveyor Diverter Gate
Dial in the extend stroke from 600 to 700 mm on site to perfectly match the diverter arm angle without machining new hard stops.
Variable-Depth Carton Stop
Use the 100 mm adjuster window to change the physical stopping distance for different package sizes on a packaging line.
Long-Reach Forming Press
Leverage the 628 N push force to actuate a forming tool over a 700 mm span while using external guides to manage side loads.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X700-100 the Right Cylinder?
When sizing this actuator, compare it against the neighbouring 32 mm bore, which provides 402 N of push force at 0.5 MPa, and the larger 50 mm bore, which delivers 982 N. The 40 mm bore sits perfectly in the middle, offering 628 N push and 528 N pull at 0.5 MPa. The adjustable stroke feature is highly useful when you want to standardize one spare cylinder across multiple stroke variants or need to dial in a precise end position on the machine. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because the 700 mm stroke is relatively long, you must support the load with an external guide to prevent rod bending and excessive side loading.
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 JSIJ40X700-100 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. The air port size is G1/4.
The -100 indicates an external adjuster that lets you shorten the extend stroke by up to 100 mm on site, giving a usable range of 600 to 700 mm. The retract end is fixed. This mechanism only sets the end position; it is not a load lock. A plain cylinder drifts on air loss, so you need an external rod lock or pilot-operated check valve to hold a load.
