Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X500-75
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X500-75 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 JSIJ32X500-75
A built-in external adjuster lets you fine-tune the extend end position from 425 to 500 mm without swapping the actuator, while the retract end stays fixed. Because it uses an extruded hard-anodized aluminum barrel, the overall body is noticeably shorter and more compact than a same-bore ISO 15552 unit.
The G1/8 port feeds the double-acting double rod, and adjustable air cushions at both ends absorb end-of-stroke impact. Note that this specific SKU lacks a magnet and cannot accept CMSE or DMSE sensors; for position feedback you need the -S version. Also, the cushion decelerates the load but does not lock it, so fit an external rod lock or pilot-operated check valve if you need to hold a load against gravity.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | 484 N |
| Max (@1.0 MPa) | 70 kgf | |
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 JSIJ32X500-75 Is Used
Adjustable Stop Positioning
Use the 75 mm extend window to dial in the exact 425 to 500 mm end position on-site for parts varying in size without machining a new stop.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X500-75 the Right Cylinder?
Conversely, if 402 N is excessive, verify your actual load requirements. The 75 mm adjustable window is highly useful for sharing a single spare cylinder across several machines that need slightly different extend end positions. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because the stroke is 500 mm, you must support the load with an external guide to prevent rod bending and excessive side loads. This non-magnet model cannot host a sensor; add the -S suffix for CMSE/DMSE switch readiness.
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 JSIJ32X500-75 FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa.
The nominal 500 mm stroke is the maximum travel. An external adjuster lets you shorten the extend stroke by up to 75 mm on-site, giving a usable extend range of 425 to 500 mm. The retract end remains fixed, and this mechanism sets the end position rather than locking the load.
