Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X75-75
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X75-75 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 75mm 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 JSIJ32X75-75
Its extruded hard-anodized aluminum barrel leaves out external tie rods entirely, making the overall body shorter and more compact than a same-bore ISO 15552 unit. The G1/8 port keeps air supply neatly routed in confined spaces.
The JSIJ32X75-75 code means the 75 mm extend stroke can be shortened on-site by up to 75 mm via an external adjuster, letting you fine-tune the end position without swapping the cylinder. This adaptability makes it ideal for sharing across stroke variants. Note this non-magnet SKU cannot take a sensor; add an -S variant for CMSE/DMSE switches.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 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 JSIJ32X75-75 Is Used
Clamp Stroke Trimming
Fine-tune the extend end-position on-site via the external adjuster to perfectly seat varying part sizes without machining new stops.
Compact Part Ejection
Fit the short JIS profile body into tight machine cells to push small finished components out of a machining zone with precise force.
Shared Spare Inventory
Keep one cylinder on the shelf and adjust the extend stroke down from 75 mm on-site to cover multiple shorter-stroke machine variants.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X75-75 the Right Cylinder?
When sizing, the 32 mm bore sits at the low edge of the family. If you need less force, there is no smaller JSIJ size, so consider reducing pressure. The 75 mm adjustable window is perfect when you need to share one spare across multiple stroke variants or trim the extend end-position on-site. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Since this is a non-S SKU, it cannot accept a magnetic sensor; choose an -S model for position detection. For any stroke over 300 mm, always use a guide rail to prevent side-load damage.
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 JSIJ32X75-75 FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa. This 32 mm bore model uses a G1/8 air port and features a 20 mm adjustable air cushion at each end.
The nominal 75 mm extend stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 75 mm, meaning the usable extend range is 0-75 mm. The retract end remains fixed. This mechanism only sets the end position; it does not lock the load. For load holding on air loss, use an external rod lock or pilot-operated check valve.
