Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X40-20
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X40-20 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 40mm 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 JSIJ32X40-20
The hard-anodized aluminum barrel keeps the build light without external retaining rods.
The JSIJ32X40-20 code means the 40 mm extend stroke can be shortened on-site by up to 20 mm via an external adjuster, letting you fine-tune the end position without swapping the cylinder. Air connects via a G1/8 port. This non-magnetic SKU cannot take a sensor; adding an -S variant enables CMSE/DMSE switches. Note that the adjustable stop sets position only—it is not a load lock, so fit an external rod lock or pilot-operated check valve if you need to hold a load against air loss.

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 JSIJ32X40-20 Is Used
Clamp Position Trimming
Dial in the exact clamping depth on small fixtures by turning the external adjuster to shorten the extend stroke within the 20 mm window.
Compact Part Ejection
Fit the short JIS profile barrel into tight machine cells to push small parts, tuning the 40 mm stroke end-point without replacing hardware.
Shared Spare Inventory
Keep one cylinder on the shelf and adjust the extend stroke down 20 mm on-site to cover multiple similar-length operations in a packaging line.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X40-20 the Right Cylinder?
The 20 mm adjustable window is ideal for sharing one spare across multiple stroke variants or trimming end positions on-site. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a non-magnet SKU, position sensing is impossible unless you specify the -S version for CMSE/DMSE switches. For any stroke over 300 mm, always guide the load to prevent side-load damage to the front cover.
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 JSIJ32X40-20 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 maximum force is 82 kgf at 1.0 MPa. The air port size is G1/8.
The nominal 40 mm extend stroke is the maximum. The -20 code means an external adjuster lets you shorten that extend stroke on-site by up to 20 mm, giving a usable extend range of 20 to 40 mm. The retract end remains fixed, and the adjuster only sets the end position—it does not lock the load.
