Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X50-20
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X50-20 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 50mm 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 JSIJ32X50-20
The nominal 50 mm stroke is the maximum, and the -20 code means you can trim that forward travel by up to 20 mm without changing the cylinder itself. This on-site tuning is ideal for dialling in a precise end position, and the hard-anodized aluminium profile barrel makes the body more compact than a same-bore ISO 15552 unit. The G1/8 port keeps air delivery proportional to the 12 mm rod.
It runs double-acting with adjustable 20 mm air cushions at both ends to decelerate the piston smoothly. Because this SKU lacks the -S magnet, it cannot take a CMSE or DMSE sensor, so position detection requires an external switch setup.

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 JSIJ32X50-20 Is Used
Clamp Position Trimming
Dial in the exact clamping reach on a fixture by trimming the forward stroke up to 20 mm, ensuring parts seat correctly without re-engineering the entire actuator setup.
Small Part Ejection
Eject lightweight moulded components from a press with a precisely tuned extend endpoint, preventing parts from flying loose by stopping the rod exactly at the chute edge.
Transfer Gate Stop
Act as an adjustable stop gate on a conveyor line where product sizes vary, allowing operators to shorten the stroke on site to match the new package dimensions quickly.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X50-20 the Right Cylinder?
When sizing this 32 mm bore, stepping down is not an option as it is the smallest available, but moving up to a 40 mm bore increases the 0.5 MPa push force to 628 N if your load grows. The adjustable stroke shines when you need to fine-tune the extend end position on the machine or want a single shared spare across slightly different stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. For any stroke length of 300 mm or longer, always use a guide rail to prevent side-load damage to the piston rod.
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 JSIJ32X50-20 FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa.
The -20 means the extend stroke can be shortened on site by up to 20 mm via an external adjuster, giving a usable extend range of 30-50 mm. The nominal 50 mm stroke is the maximum, and the retract end remains fixed. Note that this stop only sets the end position; it does not hold the load on air loss, so you need an external rod lock or pilot-operated check valve for holding.
