Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-10
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-10 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm 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 JSIJ50X700-10
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder provides a 700 mm extend stroke that can be fine-tuned down by 10 mm on-site via an external stop screw. The hard-anodized aluminium barrel omits tie rods entirely, making the body shorter and more compact than a same-bore ISO 15552 unit. It handles about 589 N of real work safely, which means lifting roughly 50 kg vertically with a 2:1 margin. Air connections use a G1/4 port.
The external adjuster lets you set the extend end position anywhere between 690 and 700 mm without changing the cylinder itself, while the retract end remains fixed. Because this SKU lacks the -S magnet option, it cannot accept CMSE or DMSE sensors for position detection. Note that the adjustable air cushions only decelerate the piston near the stroke ends; they do not hold the load if air pressure drops, so fit an external rod lock or pilot-operated check valve for vertical holding.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-10 Is Used
Long-Reach Lift Gates
Raises heavy access gates using the 982 N push force, using the 10 mm adjuster to dial in the exact 690 mm closed gap without swapping hardware.
Extended Transfer Push
Pushes pallets down a 700 mm lane, relying on the external guide to handle the long stroke while the air cushion decelerates the load smoothly.
High-Bay Divert Arm
Actuates a sorting arm at height where the compact JIS profile saves valuable vertical space compared to a standard ISO 15552 cylinder.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-10 the Right Cylinder?
When sizing this 50 mm bore, the neighbouring 40 mm bore yields 628 N push at 0.5 MPa while the 63 mm bore jumps to 1559 N, giving you clear steps if the 982 N output is too high or low. The 10 mm adjustable window is ideal for sharing a single spare cylinder across several machines that need slightly different extend end positions within that 690-700 mm range. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because the 700 mm stroke creates a long lever arm, you must use external guides to prevent rod bending and side loads. This non-magnet SKU cannot take sensors; choose the -S version if you need CMSE/DMSE switches.
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 JSIJ50X700-10 FAQ
At 0.5 MPa it pushes 982 N and pulls 825 N. At 0.7 MPa it pushes 1374 N and pulls 1154 N. The theoretical maximum force is 200 kgf at 1.0 MPa. The air port size is G1/4, the rod is 20 mm, and the adjustable cushion stroke is 20.5 mm at each end.
The nominal 700 mm stroke is the maximum extend length. The external stop screw lets you shorten the extend stroke by up to 10 mm on-site, giving a usable range of 690 to 700 mm for fine-tuning the end position. The retract end is fixed, and this stop mechanism is not a load lock.
