Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X80-10S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X80-10S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 80mm 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 JSIJ40X80-10S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder is built shorter than a same-bore ISO 15552 unit. The hard-anodized aluminum barrel lacks external tie rods, keeping the body clean and compact. A built-in magnet (-S) allows CMSE or DMSE sensors to drop directly into the side grooves for precise position detection.
The -10 code means an external adjuster can shorten the extend stroke by up to 10 mm on site, giving a usable range of 70 to 80 mm without changing the cylinder itself. It handles a safe working load of about 377 N, which is roughly 32 kg lifted vertically with a 2:1 margin. Pneumatic connections use a G1/4 port, and the retract end remains fixed while you fine-tune the extend position.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X80-10S Is Used
Clamp Position Trimming
Dial in the exact 70 to 80 mm extend reach on a machining fixture so the clamp seats parts perfectly without swapping cylinders.
Transfer Gate Adjust
Fine-tune the divert stroke on a conveyor line by 10 mm to accommodate different package sizes on the fly.
Compact Sorting Push
Use the short JIS profile body and integrated magnet to push parcels in tight logistics cells where space is limited.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X80-10S the Right Cylinder?
Size this 40 mm bore against the 32 mm option (402 N push at 0.5 MPa) or the 50 mm option (982 N push at 0.5 MPa) to match your force requirements. The adjustable stroke is ideal when you need to fine-tune the extend end position on site or want a shared spare across slight stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The included -S magnet supports CMSE/DMSE switches. For any stroke over 300 mm, always use a guide 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 JSIJ40X80-10S 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.
The nominal 80 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 10 mm on site, yielding a usable range of 70 to 80 mm. The retract end is fixed, and this mechanism sets end position rather than holding the load.
