Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X400-50S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X400-50S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 400mm 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 JSIJ32X400-50S
The extruded hard-anodized aluminum body makes it shorter and more compact than a same-bore ISO 15552 unit, while the G1/8 port keeps pneumatic connections small.
The -50 code means an external adjuster can shorten the extend stroke on-site by up to 50 mm, giving a usable range of 350-400 mm without changing the cylinder itself. Because it carries the -S suffix, a built-in piston magnet works directly with CMSE/DMSE sensors in the side grooves. The retract end remains fixed, and the adjustable air cushions at both ends only decelerate the piston—they do not hold the load if air pressure drops.

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 JSIJ32X400-50S Is Used
Adjustable Stop Positioning
Use the 50 mm extend window to fine-tune the end position of a parts pusher on-site, allowing a 350-400 mm stroke range without swapping the cylinder.
Sensed Pick-and-Place
The built-in magnet supports CMSE/DMSE switches for precise end-of-stroke confirmation in automated handling routines moving 20 kg vertical loads.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X400-50S the Right Cylinder?
The adjustable stroke is ideal when you need to fine-tune the extend end position on-site or want a single spare part that covers several stroke variants. Mounting choices include Basic, FA, LB, TC, TCM1, and TCM2. Because the 400 mm stroke is relatively long, always use an external guide to prevent rod bending and side-load wear. The -S magnet allows direct CMSE/DMSE sensors for position feedback.
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 JSIJ32X400-50S FAQ
This 32 mm bore cylinder has a G1/8 port.
The nominal 400 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 50 mm on-site, giving a usable extend range of 350-400 mm. The retract end is fixed, and this mechanism only sets the end position—it does not lock the load.
