Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-75
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-75 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 500mm 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 JSIJ50X500-75
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder shortens the extend stroke on-site by up to 75 mm via an external adjuster. The nominal 500 mm stroke remains the maximum travel, letting you fine-tune the end position without swapping the actuator. Its hard-anodized aluminium barrel omits tie rods entirely, making the body more compact than a same-bore ISO 15552 unit. The G1/4 port feeds the dual adjustable air cushions.
Built for double-acting single-rod duty, it handles a safe working load of roughly 589 N, which translates to lifting about 50 kg vertically with a 2:1 safety margin. Because this SKU lacks the -S magnet, it cannot accept CMSE or DMSE sensors. Note that the adjustable stop sets position only; on air loss the piston drifts, so fit an external rod lock or pilot-operated check valve to hold a suspended load.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-75 Is Used
Conveyor Diverter Trim
Fine-tune the 500 mm extend reach by up to 75 mm to match varying package sizes on a sorting line without changing the cylinder.
Stacker Height Calibration
Adjust the extend endpoint on-site to set precise stacking heights, using the 982 N push force to index loads smoothly.
Press Pin Depth Setting
Dial in the exact insertion depth within the 425-500 mm usable stroke window, avoiding mechanical hard-stops on the fixture.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-75 the Right Cylinder?
This 50 mm bore generates 982 N push at 0.5 MPa, sitting neatly between the 628 N of a 40 mm bore and the 1559 N of a 63 mm bore. The -75 mm adjuster is ideal when you need to share one spare cylinder across several stroke variants or trim the end position on-site. JSIJ mounting options include FA, LB, TC, TCM1 and TCM2. As the 500 mm stroke invites rod bending, always use an external guide to absorb side loads. Since this non-S SKU has no magnet, position sensing is impossible here; choose the -S version for 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 JSIJ50X500-75 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 is 200 kgf at 1.0 MPa, and the air port is G1/4.
An external stop screw lets you shorten the extend stroke by up to 75 mm on-site, giving a usable extend range of 425 to 500 mm. The nominal 500 mm stroke is the maximum travel, and the retract end remains fixed.
