Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X75-40
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X75-40 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 JSIJ32X75-40
The external stop screw lets you trim the forward stroke by up to 40 mm, so the usable extend range becomes 35-75 mm while the retract end stays fixed. You can fine-tune the end position without physically swapping the cylinder. Built as a JIS profile unit, its hard-anodized aluminum barrel makes it shorter and more compact than a same-bore ISO 15552 cylinder.
The G1/8 port feeds the double-acting double-rod system, and adjustable air cushions at both ends absorb impact. Note that this specific SKU lacks a magnet, so it cannot take a CMSE or DMSE sensor. The cushion only decelerates the piston near the ends; it will not hold a load on air loss, so fit an external rod lock or pilot-operated check valve for vertical holding.

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 JSIJ32X75-40 Is Used
Tooling Depth Dial-In
Trim the extend stroke by up to 40 mm on-site to set exact clamping depth without machining new spacers or replacing the cylinder.
Compact Part Ejection
Fit the shorter JIS profile body into tight machine frames to push small parts out of a mold, adjusting the reach as tooling wears.
Shared Spare Inventory
Keep one cylinder as a backup for multiple 75 mm stations, using the external stop screw to match the exact required stroke on the floor.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X75-40 the Right Cylinder?
The 40 mm adjustable window is ideal when you need to share one spare cylinder across multiple stroke variants or dial in a precise end position after a tooling change. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a non-magnet SKU, you cannot mount position sensors; choose the -S variant if you need CMSE or DMSE switches. For any stroke at or above 300 mm, always guide the load to prevent side-load damage to the rod seals.
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 JSIJ32X75-40 FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa. This 32 mm bore uses a G1/8 air port and features a 12 mm rod with an M10x1.25 thread.
The nominal maximum stroke is 75 mm. The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, giving a usable extend range of 35-75 mm. The retract end is fixed. This mechanism sets the end position but does not lock the load.
