Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X75-20
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X75-20 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 JSIJ32X75-20
The hard-anodized aluminium barrel keeps the assembly light while the G1/8 port feeds the double-acting double rod.
The -20 code means an external stop screw lets you shorten the extend stroke on-site by up to 20 mm, giving a usable 55-75 mm range while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder. This plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor, so order an -S variant if you need position detection.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |

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 JSIJ32X75-20 Is Used
Clamp Position Trimming
Dial in the exact clamping depth on a fixture by adjusting the extend stroke 55-75 mm on-site without machining new stops.
Compact Part Ejection
Fit a short 32 mm ejection pusher into a tight machine cell where the JIS profile body saves valuable length.
Shared Spare Inventory
Keep one cylinder as a universal spare and set the extend window to 55 mm or 75 mm to match various downstream stations.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X75-20 the Right Cylinder?
This 32 mm bore sits at the low edge of the JSIJ range, so if you need more push consider the 40 mm bore which gives 628 N at 0.5 MPa. The on-site adjuster is ideal when you share one spare across several stroke variants or need to trim the end position after mechanical tweaks. Mounting options include FA, LB, TC, TCM1 and TCM2. Because the 75 mm stroke is under 300 mm, side-load risk is low, but always guide the load for any stroke over 300 mm. Remember this non-magnetic SKU cannot fit a sensor.
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 JSIJ32X75-20 FAQ
At 0.5 MPa it pushes 402 N and pulls 345 N. At 0.7 MPa it pushes 563 N and pulls 483 N. The theoretical max is 82 kgf at 1.0 MPa. The air port is G1/8, the rod is 12 mm with an M10x1.25 thread, and it has 20 mm adjustable air cushions at both ends.
The 75 mm nominal stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 20 mm on-site, yielding a usable extend range of 55-75 mm. The retract end is fixed. This stop only sets the end position and does not lock the load; use an external rod lock or pilot-operated check valve if you need to hold a load on air loss.
