Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X500-20
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X500-20 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 500mm stroke, G1/8 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 JSIJ32X500-20
It drives a 12 mm rod through a 500 mm stroke, threading via an M10x1.25 end and breathing through a G1/8 port. The external stop screw lets you trim the extend stroke on-site by up to 20 mm, meaning the usable forward travel spans 480 to 500 mm while the retract end remains fixed. This mechanism allows you to fine-tune the end position without physically remounting or swapping the actuator. The adjustable 20 mm air cushions at each end absorb kinetic energy near the stroke limits but do not function as a load lock. Because this specific SKU lacks the -S magnet option, it cannot accept CMSE or DMSE position sensors.
Operating between 0.15 and 1.0 MPa within a -20 to +70 C environment, the unit relies on NBR piston seals and TPU buffer gaskets for longevity. Running at speeds of 30-800 mm/s, the 500 mm travel length demands careful external guidance to prevent rod bending under side loads. If your application requires the payload to stay put during a complete air loss, you must pair the cylinder with an external rod lock or a pilot-operated check valve, as the standard pneumatic circuit will drift.

JSIJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X500-20 Is Used
Sorter Diverter Tuning
Trimming the 500 mm extend stroke by up to 20 mm on-site lets you perfectly align a package diverter arm without machining new hard stops.
Lab Test Actuation
Ideal for cycling a test rig at 30-800 mm/s where the exact 480 to 500 mm end position must be dialed in precisely after installation.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X500-20 the Right Cylinder?
When sizing this model, consider the neighboring bores: dropping down is not an option below 32 mm, but stepping up to a 40 mm bore increases the 0.5 MPa push force to 628 N if your payload exceeds the safe 241 N working load. The 20 mm adjustable extend window is highly useful when you need to share a single spare cylinder across multiple machines that have slightly different end-position requirements, saving inventory space. You can mount this actuator using basic, FA, LB, TC, TCM1, or TCM2 brackets. Since this is a non-magnetized SKU, it cannot host CMSE or DMSE sensors; you would need to specify the -S variant for position detection. Finally, at a 500 mm stroke, always support the load with an external linear guide to prevent excessive rod bending and premature seal wear.
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 JSIJ32X500-20 FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa. This 32 mm bore cylinder uses a G1/8 air port.
An external stop screw lets you shorten the extend stroke on-site by up to 20 mm. The usable forward travel is 480 to 500 mm, with the 500 mm nominal stroke being the maximum. The retract end is fixed and cannot be adjusted.
