Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X150-50S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X150-50S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 150mm 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 JSIJ50X150-50S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder keeps your machinery compact by being noticeably shorter than a same-bore ISO 15552 unit. The hard-anodized aluminium barrel avoids external tie rods for a clean profile. It handles about 589 N of real work safely, which translates to lifting roughly 50 kg vertically with a 2:1 margin.
The -50S code means an external adjuster can shorten the 150 mm extend stroke on-site by up to 50 mm, giving a usable range of 100-150 mm without swapping the cylinder. The retract end remains fixed, and the G1/4 port matches the bore standard. Because this is an -S SKU, a built-in piston magnet lets you drop CMSE/DMSE reed or electronic switches straight into the side grooves for position sensing.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X150-50S Is Used
Clamp Stroke Tuning
Dial in the exact clamping reach on machining fixtures by shortening the extend stroke up to 50 mm on-site without replacing the cylinder.
Variable Transfer Stops
Adjust the diverting arm end position on the fly for different package sizes, using the 100-150 mm usable window to accommodate product changes.
Vertical Lift Positioning
Lift approximately 50 kg loads vertically and fine-tune the upper stopping point precisely, relying on the built-in magnet for confirmation.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X150-50S the Right Cylinder?
When sizing, the neighbouring 40 mm bore gives 628 N push at 0.5 MPa, while the 63 mm bore jumps to 1559 N, so the 50 mm sits right in the middle for moderate loads. The adjustable stroke is ideal for fine-tuning end positions on-site or sharing one spare across multiple stroke variants. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. The -S magnet supports CMSE/DMSE sensors. For any stroke over 300 mm, always guide the load to prevent side-load damage. Remember the external stop screw sets position only; it is not a load lock.
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 JSIJ50X150-50S 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 force is 200 kgf at 1.0 MPa. This 50 mm bore model uses a G1/4 air port and features a 20 mm rod with an M18x1.5 thread.
The -50 indicates an external adjuster that shortens the extend stroke by up to 50 mm on-site, giving a usable extend range of 100-150 mm while the retract end stays fixed. The S denotes a built-in piston magnet for CMSE/DMSE switches. Note that a plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve to hold a load.
