Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X75-20S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X75-20S 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 JSIJ32X75-20S
The external adjuster lets you shorten the extend stroke by up to 20 mm, giving a usable range of 55-75 mm without swapping the cylinder. Its hard-anodized aluminum profile barrel makes it shorter and more compact than a same-bore ISO 15552 unit. The built-in magnet (-S) supports CMSE/DMSE sensors in the side grooves.
It uses a G1/8 port and a 12 mm rod. The 20 mm adjustable air cushions decelerate the piston near the ends, but remember the cylinder does not hold load on air loss—use an external rod lock or pilot-operated check valve for that.

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 JSIJ32X75-20S Is Used
Pick-and-Place Refinement
Dial in the exact 55-75 mm extend reach for small component transfer without machining new hard stops.
Sorting Diverter Tuning
Adjust the extend stroke on-site to perfectly deflect varying product sizes on a packaging line.
Compact Clamping Assembly
Fit a clamping actuator into a tight JIS footprint while retaining the ability to tweak grip distance.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X75-20S the Right Cylinder?
When sizing, the 32 mm bore sits at the low edge of the range; if your application needs more push than the 563 N available at 0.7 MPa, step up to the 40 mm bore which yields 628 N at 0.5 MPa. Conversely, if your load is very light, this bore is optimal. The -20 mm adjustable window is ideal when you need to fine-tune the extend end position on-site or want a single spare cylinder to cover several slightly different stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. The -S suffix means a magnet is already included for CMSE/DMSE switches. For any stroke length over 300 mm, 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 JSIJ32X75-20S FAQ
This 32 mm bore cylinder has a G1/8 port.
The nominal stroke is 75 mm maximum. An external stop screw lets you shorten the extend stroke on-site by up to 20 mm, yielding a usable extend range of 55-75 mm. The retract end is fixed, and this mechanism only sets the end position—it is not a load lock.
