Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X75-75S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X75-75S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 75mm 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 JSIJ32X75-75S
The extruded hard-anodized aluminium profile barrel keeps the body shorter and more compact than a same-bore ISO 15552 cylinder. A G1/8 port feeds the double-acting double-rod piston, while adjustable air cushions of 20 mm decelerate the load at each end.
The external stop screw lets you trim the extend stroke down from the 75 mm maximum right on the floor, giving a usable extend window of 0-75 mm without swapping the actuator. Because this is an -S SKU, a built-in piston magnet works with CMSE/DMSE reed or electronic switches that drop directly into the side grooves. The retract end remains fixed, and the stop sets end position rather than locking the load.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |

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 JSIJ32X75-75S Is Used
Probe Positioning
Dial in the exact 0-75 mm extend reach of a testing probe on the production line without physically remounting the actuator.
Small Part Ejection
Fine-tune the ejection stroke of small machined components out of a fixture, adapting the end point dynamically to part height.
Sensor Alignment
Leverage the built-in magnet and CMSE/DMSE switches to confirm the adjusted extend position for a vision system inspection gate.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X75-75S the Right Cylinder?
When sizing this 32 mm bore, stepping up to the 40 mm bore raises the 0.5 MPa push force to 628 N, while dropping below 32 mm is not standard in this JIS series. The 75 mm adjustable window is ideal for sharing one spare cylinder across multiple stroke variants or fine-tuning a final end position during machine commissioning. You can mount it via Basic, FA, LB, TC, TCM1, or TCM2 brackets. For any stroke at or above 300 mm, use an external guide rail to prevent side-load wear on the 12 mm rod.
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 JSIJ32X75-75S FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa. The air port is G1/8.
The nominal 75 mm is the maximum extend stroke. The external adjuster lets you shorten the extend stroke on-site by up to 75 mm, yielding a usable extend window of 0-75 mm. The retract end is fixed, and the adjuster only sets the end position; it does not lock the load.
