Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X275-30S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X275-30S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 275mm 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 JSIJ32X275-30S
The hard-anodized aluminum barrel makes it shorter than a same-bore ISO 15552 cylinder. A built-in magnet (-S) allows CMSE or DMSE sensors to drop directly into the side grooves.
The external stop screw lets you trim the extend stroke by up to 30 mm on site, giving a usable 245-275 mm range while the retract end stays fixed. Air connects via a G1/8 port, and adjustable cushions decelerate the 12 mm rod at both ends.

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 JSIJ32X275-30S Is Used
End-Position Trimming
Dial in the exact extend stop within the 245-275 mm window during machine commissioning without swapping the cylinder.
Compact JIS Clamping
Fits a 32 mm clamping station where a longer ISO 15552 cylinder would foul the surrounding tooling.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X275-30S the Right Cylinder?
The -30 mm adjustable window is ideal for tuning end positions on site or sharing one spare across several stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a 275 mm stroke, add a guide to prevent side-load wear on the rod. The -S suffix means a magnet is already fitted for CMSE/DMSE switches.
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 JSIJ32X275-30S 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 max is 82 kgf at 1.0 MPa. The air port is G1/8.
The nominal 275 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 30 mm on site, yielding a 245-275 mm usable range. The retract end is fixed. This stop sets position only; it does not lock the load.
