Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X75-40S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X75-40S 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 JSIJ32X75-40S
Its extruded hard-anodized aluminum barrel leaves out external rods, making the total body shorter and more compact than a same-bore ISO 15552 unit. The integrated -S magnet allows CMSE or DMSE sensors to drop directly into the side grooves for precise position detection.
The -40 code means an external adjuster can shorten the extend stroke on-site by up to 40 mm, giving a usable range of 35 to 75 mm without swapping the cylinder. This on-site tuning is ideal for dialing in end positions, while the G1/8 port keeps pneumatic connections simple.

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 JSIJ32X75-40S Is Used
Gauge Position Trimming
Dial in the exact extend stop on a small parts gauge between 35 and 75 mm without machining new mounts.
Light Ejector Setup
Tune the ejection reach on a packaging line to push 20 kg boxes cleanly without overtravel.
Shared Spare Cylinder
Keep one adjustable unit in maintenance stock to cover various 32 mm bore sub-100 mm stroke machines.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X75-40S the Right Cylinder?
The adjustable stroke shines when you need to share one spare across multiple stroke variants or fine-tune a final end position on the machine. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this SKU includes the -S magnet, it is ready for CMSE/DMSE switches. For any stroke at or above 300 mm, always guide the load to prevent rod side-load damage.
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 JSIJ32X75-40S FAQ
At 0.5 MPa it pushes 402 N and pulls 345 N. At 0.7 MPa it pushes 563 N and pulls 483 N. The theoretical maximum force is 82 kgf at 1.0 MPa. This 32 mm bore unit uses a G1/8 air port and features a 20 mm adjustable air cushion at each end.
The 75 mm nominal stroke is the maximum extend length. An external stop screw lets you shorten the extend stroke on-site by up to 40 mm, giving a usable range of 35 to 75 mm. The retract end is fixed, and this stop only sets the end position; it does not lock the load.
