Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-40
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-40 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 800mm 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 JSIJ50X800-40
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for long-reach actuation where the exact end position needs on-site tuning. The extruded hard-anodized aluminium barrel keeps the body more compact than a same-bore ISO 15552 unit. A G1/4 port supplies the air, and adjustable air cushions of 20.5 mm absorb shock at both ends.
The external -40 adjuster lets you shorten the extend stroke from the 800 mm maximum down to 760 mm without swapping the cylinder. This mechanism sets the end position but is not a load lock. In practice it handles about 589 N of safe working load, roughly 50 kg lifted vertically with a 2:1 margin. Note this SKU lacks a magnet, so it cannot take CMSE/DMSE sensors; add the -S variant for position detection.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-40 Is Used
Long-Transfer Push-Off
Pushes parts off a belt at an 800 mm maximum reach, dialed back 40 mm on-site to hit a moving gate precisely.
Storage Lane Diverter
Extends into a pallet lane and uses the adjuster to fine-tune the stopping point for mixed box sizes without changing the cylinder.
Vertical Lowering Arm
Lowers a 50 kg fixture over a 760-800 mm drop, relying on the external stop to set the exact down position safely.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-40 the Right Cylinder?
Size this 50 mm bore against its neighbours: a 40 mm gives 628 N push at 0.5 MPa, while a 63 mm yields 1559 N. The adjustable stroke is ideal when you want one shared spare across stroke variants or need to fine-tune a 760-800 mm extend end on-site. Mounting options include FA, LB, TC, TCM1 and TCM2. Because the 800 mm stroke invites rod bending, always support the load with an external guide to prevent side-load damage. Remember this no-magnet SKU cannot host a sensor.
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 JSIJ50X800-40 FAQ
At 0.5 MPa it pushes 982 N and pulls 825 N. At 0.7 MPa push is 1374 N and pull is 1154 N. The theoretical maximum force is 200 kgf at 1.0 MPa. It uses a G1/4 port and a 20 mm rod with an M18x1.5 thread.
The external stop screw lets you shorten the extend stroke on-site by up to 40 mm. Usable extend is 760-800 mm, with 800 mm being the maximum. The retract end is fixed. This stop only sets the end position; it does not hold the load on air loss, so use a pilot-operated check valve for holding.
