Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X300-75S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X300-75S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 300mm 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 JSIJ32X300-75S
The hard-anodized aluminum barrel uses no external tie rods, and the G1/8 port keeps pneumatic plumbing compact.
A built-in magnet (-S) lets you drop CMSE or DMSE reed and electronic switches straight into the side grooves for position sensing. The external adjuster allows you to shorten the extend stroke on site by up to 75 mm, giving a usable range of 225-300 mm so you can fine-tune the end position without swapping the cylinder.

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 JSIJ32X300-75S Is Used
Gauge Position Trimming
Dial in the exact extend end-point within the 225-300 mm window on a test rig without machining new hard stops.
Sensor-Driven Clamping
Use the built-in magnet with CMSE switches to confirm clamp position before initiating the next machining cycle.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X300-75S the Right Cylinder?
The on-site adjustability is ideal when you need to share a spare across stroke variants or dial in the exact end position after mechanical mounting. Choose from basic, FA, LB, TC, TCM1, or TCM2 mounts. Because the 300 mm stroke creates leverage, use an external guide to prevent rod bending and manage side loads. The -S variant includes the piston magnet for sensors.
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 JSIJ32X300-75S FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa. The air port size is G1/8.
The nominal 300 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on site by up to 75 mm, yielding a usable extend range of 225-300 mm. The retract end is fixed, and this mechanism only sets the end position rather than holding the load.
