Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X300-40S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X300-40S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 300mm 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 JSIJ32X300-40S
The extruded hard-anodized aluminum profile barrel makes it shorter and more compact than an ISO 15552 cylinder of the same bore.
A -40 mm external adjuster lets you shorten the extend stroke on site from the 300 mm maximum down to 260 mm, fine-tuning the end position without swapping the cylinder. The retract end is fixed, and the built-in magnet (-S) supports CMSE/DMSE sensors in the side grooves. The adjustable air cushions only decelerate the piston near the ends; they do not hold the load on air loss, so use an external rod lock for vertical 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 JSIJ32X300-40S Is Used
Gauge Positioning
Dial in the exact measurement contact point by trimming the extend stroke up to 40 mm on site, ensuring precise gauge alignment without remounting hardware.
Light Part Ejector
Safely pushes 20 kg assemblies out of a fixture, using the adjustable stop to account for varying part widths while keeping the retract position fixed.
Clamp Stroke Tuning
Set the exact clamping reach on a machining line by shortening the 300 mm extend window, preventing over-travel on delicate workpieces.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X300-40S the Right Cylinder?
The -40 mm adjustable window is ideal for on-site end-position tuning or sharing a spare across stroke variants. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. The -S suffix means a magnet is present for CMSE/DMSE switches. Because the 300 mm stroke is relatively long, always use an external guide to prevent rod bending and side loads.
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 JSIJ32X300-40S FAQ
The external adjuster lets you shorten the extend stroke on site by up to 40 mm, giving a usable extend range of 260-300 mm (the 300 mm nominal stroke is the maximum). The retract end remains fixed.
