Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X175-30
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X175-30 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 175mm 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 JSIJ32X175-30
It is a double-acting double-rod actuator with an external adjuster that lets you shorten the extend stroke on site by up to 30 mm, giving a usable range of 145-175 mm while the retract end stays fixed. The nominal 175 mm stroke is the maximum, so you can fine-tune the end position without physically swapping the cylinder. This bore carries a 12 mm rod, an M10x1.25 rod-end thread, a G1/8 port, and 20 mm adjustable air cushions at both ends. Because this SKU lacks the -S magnet option, it cannot accept CMSE or DMSE sensors.
Note that the air cushions only decelerate the piston near the stroke ends; a plain actuator like this will drift and cannot hold a load on air loss or when a valve is centered. To maintain position under those conditions you need an external rod lock or a pilot-operated check valve. The cylinder operates between 0.15 and 1.0 MPa at speeds of 30-800 mm/s, and the external stop screw sets the end position rather than acting as a brake.

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 JSIJ32X175-30 Is Used
End-Stop Trimming
Dial in the exact extend position of a small clamping jaw on site by shortening the stroke up to 30 mm without changing the physical cylinder mount.
Adjustable Gauge Stop
Use the external adjuster to set a precise 145-175 mm extend length for positioning material stops against varying product widths.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X175-30 the Right Cylinder?
The adjustable stroke window shines when you need to dial in a precise end position on the machine or want a single shared spare part that can cover slight stroke variations on site. You can mount it using the basic body, FA, LB, TC, TCM1, or TCM2 brackets. For a 175 mm stroke, always guide the load to prevent side-loading forces from damaging the 12 mm rod seals. Since this specific model has no -S suffix, it cannot support magnetic position sensing; choose an -S variant if your control system requires CMSE or 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 JSIJ32X175-30 FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa. It features a 32 mm bore, a 12 mm rod with an M10x1.25 thread, a G1/8 port, and 20 mm adjustable cushions at both ends.
The external stop screw lets you shorten the extend stroke on site by up to 30 mm. The usable extend range is 145-175 mm, with the nominal 175 mm being the maximum length. The retract end remains fixed, and the stop screw only sets the end position rather than locking the load.
