Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X225-50S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X225-50S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 225mm 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 JSIJ32X225-50S
The nominal 225 mm stroke remains the maximum travel, letting you fine-tune the end position without swapping the actuator. Its extruded hard-anodized aluminum barrel omits tie rods entirely, making the body shorter and more compact than a same-bore ISO 15552 unit. The integrated -S magnet allows CMSE or DMSE switches to drop directly into the side grooves for position sensing.
Pneumatic connections use a G1/8 port, while a 20 mm adjustable air cushion at each end manages end-of-stroke deceleration. Remember that a standard cylinder cannot hold a load on air loss; the cushion only slows the piston, so fit an external rod lock or pilot-operated check valve if you need strict load holding.

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 JSIJ32X225-50S Is Used
Dial-In Clamping Stops
Use the 50 mm extend window to fine-tune the clamping contact point on machined parts without physically shimming the cylinder body.
Adjustable Pick-and-Place
Vary the pick height dynamically on the fly across mixed product batches by backing out the external stop screw from 225 mm down to 175 mm.
Compact Diverting Arm
Fit a shorter JIS profile body into tight transfer stations while maintaining precise end-of-stroke positioning for small package routing.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X225-50S the Right Cylinder?
Size this 32 mm bore against the 40 mm option, which raises the 0.5 MPa push force to 628 N, or drop to a smaller unit if your load is extremely light. The -50 mm adjustable window is ideal when you need to share one spare cylinder across several stroke variants or dial in a precise end position on the machine. You can mount it using basic, FA, LB, TC, TCM1, or TCM2 brackets. The -S suffix means a magnet is already built in for CMSE/DMSE sensors; a non-S SKU cannot accept them. Because the 225 mm stroke exceeds 300 mm? No, but for any stroke at or above 300 mm, always guide the load to prevent rod side-loading.
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 JSIJ32X225-50S FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa. The air port size is G1/8.
The external adjuster lets you shorten the extend stroke on site by up to 50 mm. The usable extend range is 175 mm to 225 mm, with 225 mm being the maximum nominal stroke. The retract end position remains fixed.
