Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X75-50
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X75-50 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 JSIJ32X75-50
The hard-anodized aluminium body is noticeably shorter than an ISO 15552 cylinder of the same bore, and the G1/8 port keeps the pneumatic footprint compact.
The JSIJ32X75-50 uses an external stop screw to shorten the extend stroke on site by up to 50 mm. Your usable extend range becomes 25 to 75 mm, letting you fine-tune the end position without swapping the cylinder, while the retract end stays fixed. Note that this plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor; add an -S variant if you need position detection.

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 JSIJ32X75-50 Is Used
Probe Plunge Depth Tuning
Dial in the exact 25 to 75 mm extend reach for a testing probe station using the external stop screw, ensuring delicate contact without reprogramming motion controllers.
Small Parts Ejector
Shorten the extend stroke on a 32 mm bore ejection gate by up to 50 mm to accommodate changing product sizes on a shared assembly fixture.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X75-50 the Right Cylinder?
When sizing this 32 mm bore, step down if your load is very light, but stepping up to a 40 mm bore boosts push force to 628 N at 0.5 MPa if you need more authority. The 50 mm adjuster window is ideal for sharing a single spare cylinder across multiple stroke variants, as you can tune the extend end position right at the machine. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because the nominal stroke is 75 mm, side-load risks are low, but for any stroke 300 mm or longer you should always guide the rod to prevent binding. Remember that the air cushion only decelerates the piston near the end of travel; it will not hold a load on air loss, so fit an external rod lock or pilot-operated check valve for vertical holding.
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 JSIJ32X75-50 FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa. It features a 12 mm rod, M10x1.25 rod thread, G1/8 port, and 20 mm adjustable air cushions at both ends.
The nominal extend stroke is 75 mm, which is the maximum. The external adjuster lets you shorten that extend stroke on site by up to 50 mm, giving a usable extend range of 25 to 75 mm so you can fine-tune the end position without changing the cylinder. The retract end is fixed.
