Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X275-50S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X275-50S 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 JSIJ32X275-50S
An external stop screw lets you fine-tune the extend end position without swapping the actuator, giving a usable extend range of 225-275 mm while the retract end stays fixed. The extruded hard-anodized aluminium barrel makes it shorter and more compact than a same-bore ISO 15552 unit.
The built-in piston magnet (-S) supports CMSE/DMSE sensors in the side grooves, and the G1/8 port matches the 32 mm bore size. Note that a plain cylinder drifts on air loss; the adjustable cushion only decelerates, so use an external rod lock for held loads.

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 JSIJ32X275-50S Is Used
End-Position Tuning
Use the 50 mm external adjuster to dial in the exact extend stop on a clamping fixture without machining new spacers.
Compact Diverter
Fits into tight JIS envelope spaces to push lightweight packages, shortening the stroke on-site if the lane gap changes.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X275-50S the Right Cylinder?
The -50 mm adjuster is ideal when you need to tune the extend end position on-site or want a single spare part covering several stroke variants around 225-275 mm. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The -S magnet allows CMSE/DMSE switches for position feedback. Because the stroke is 275 mm, ensure adequate side-load guidance to prevent rod bearing wear.
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 JSIJ32X275-50S FAQ
The theoretical max force is 82 kgf at 1.0 MPa. This 32 mm bore model uses a G1/8 port.
The nominal 275 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 50 mm on-site, giving a usable extend range of 225-275 mm. The retract end remains fixed, and the stop sets position rather than locking the load.
