Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X125-100S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X125-100S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 125mm 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 JSIJ32X125-100S
The hard-anodized aluminum extruded barrel keeps the assembly light without external support rods.
The -100S designation means the external adjuster can shorten the extend stroke on-site by up to 100 mm, yielding a usable forward travel range of 25 to 125 mm while the retract end remains fixed. This lets you fine-tune the end position mechanically without swapping the cylinder. The built-in magnet works seamlessly with CMSE/DMSE sensors in the side grooves for precise position detection.

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 JSIJ32X125-100S Is Used
Pick-and-Place Dial Tuning
Dial in the exact 25-125 mm extend reach for a small parts gripper on the fly, ensuring precise placement without machining new hard stops.
Variable Depth Carton Sealing
Adjust the forward stroke on-site to match different box depths, using the compact 32 mm profile to fit tight packaging cell clearances.
Shared Spare Cylinder
Keep one cylinder as a plant-wide spare for multiple 32 mm machines, shortening the extend travel from 125 mm down to 25 mm as each station requires.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X125-100S the Right Cylinder?
The adjustable 25-125 mm extend window is ideal for sharing a single spare cylinder across multiple stroke variants or dialing in exact end positions on-site. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The -S magnet supports CMSE/DMSE switches for end-of-stroke confirmation. For any stroke at or above 300 mm, always use a guide rail to prevent side-load wear on the rod seals.
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 JSIJ32X125-100S FAQ
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 12 mm piston rod.
The nominal stroke is 125 mm, but an external adjuster lets you shorten the extend stroke on-site by up to 100 mm, giving a usable forward range of 25 to 125 mm. The retract end is fixed. This mechanism sets the end position and decelerates the load, but it is not a load lock; for holding a load on air loss, use an external rod lock or pilot-operated check valve.
