Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-100S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-100S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 800mm stroke, G1/4 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 JSIJ50X800-100S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for applications needing exact end-position tuning on site. An external stop screw lets you shorten the extend stroke by up to 100 mm, giving a usable range of 700-800 mm while the retract end remains fixed. The hard-anodized aluminum extruded body makes it shorter and more compact than a same-bore ISO 15552 unit. It handles about 589 N of real work safely, which means lifting roughly 50 kg vertically with a 2:1 margin.
This -S variant includes a built-in piston magnet for CMSE/DMSE switches that drop directly into the side grooves. Air connects via the G1/4 port, and adjustable air cushions of 20.5 mm at each end absorb kinetic energy. The stop screw sets the extend endpoint but does not lock the load; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve for holding. Because the 800 mm stroke is long, use external guides to prevent rod bending and side loads.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-100S Is Used
Conveyor Diverter Tuning
Fine-tune the 700-800 mm extend reach on site to push varying box sizes onto downstream lanes without swapping the cylinder.
Vertical Material Lift
Lifts roughly 50 kg using the 982 N push force, with the 100 mm adjuster allowing precise height calibration at the upper stop.
Long-Reach Clamping
Holds parts at extended distances where the 800 mm nominal stroke is shortened on-site to accommodate different fixture widths.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-100S the Right Cylinder?
When sizing this unit, the 50 mm bore sits between the 40 mm class (628 N push at 0.5 MPa) and the 63 mm class (1559 N push at 0.5 MPa). The adjustable window is ideal when you need to fine-tune the extend endpoint across multiple machines or share a single spare across stroke variants. You can mount it using FA, LB, TC, TCM1, or TCM2 brackets. The -S magnet enables CMSE/DMSE sensor placement for position confirmation. For the 800 mm stroke, always support the load with external guides to avoid rod bending and premature seal wear.
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 JSIJ50X800-100S FAQ
At 0.5 MPa it pushes 982 N and pulls 825 N. At 0.7 MPa it pushes 1374 N and pulls 1154 N. The theoretical maximum is 200 kgf at 1.0 MPa. The air port is G1/4.
The nominal 800 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 100 mm on site, yielding a usable extend range of 700-800 mm. The retract end is fixed, and the stop screw only sets the end position; it does not hold the load on air loss.
