Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X50-40
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X50-40 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 JSIJ32X50-40
The G1/8 port feeds the chamber efficiently for this compact class.
The external adjuster lets you shorten the extend stroke on site by up to 40 mm, dropping the usable forward travel from the 50 mm maximum down to 10 mm without swapping the cylinder. The retract end stays fixed. Note that this plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor; for the sensing version you need the -S variant.

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 JSIJ32X50-40 Is Used
Probe Positioning
Dial in the exact 10 to 50 mm extend contact point for a testing probe without machining custom spacers.
Small Part Ejection
Shorten the ejection stroke on-site by 40 mm to prevent a delicate plastic component from flying off the fixture.
Compact Clamping
Fit a shorter JIS profile body into a tight 32 mm bore clamping station where ISO 15552 lengths fail.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X50-40 the Right Cylinder?
Dropping down is rarely practical as 32 mm is the low edge of the range. The 40 mm adjuster window is ideal when you need to fine-tune the end position on-site or want a shared spare across slight stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Since this is a 50 mm stroke, side-load guiding is less critical, but always guide the load for any stroke reaching 300 mm or more. Remember that a plain cylinder does not hold load on air loss; add an external rod lock or pilot-operated check valve if you need true 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 JSIJ32X50-40 FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa. It uses a G1/8 port and a 20 mm adjustable air cushion at each end.
The nominal 50 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 40 mm, yielding a usable forward travel of 10 to 50 mm. The retract end remains fixed, and this stop only sets the end position rather than locking the load.
