Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X25-10S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X25-10S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 25mm 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 JSIJ50X25-10S
Generating 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for tight spaces where end-position tuning is required. The hard-anodized aluminium barrel makes it shorter and more compact than a same-bore ISO 15552 unit. It handles about 589 N of real work safely, which translates to lifting roughly 50 kg vertically with a 2:1 margin.
The -10 code means an external stop screw lets you shorten the 25 mm extend stroke on-site by up to 10 mm, giving a usable range of 15 to 25 mm without changing the cylinder itself. Because this is an -S SKU, a built-in piston magnet works with CMSE/DMSE switches in the side grooves. Air connects via the G1/4 port. Note that the cushion only decelerates; use an external rod lock or pilot-operated check valve to hold a load.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X25-10S Is Used
Short-Stroke Clamping
Dial in the exact 15 to 25 mm clamp reach on-site to seat delicate parts without swapping the entire actuator.
Sensor-Ready Sorting
Use the built-in magnet with CMSE/DMSE switches to confirm part ejection in a high-speed sorting lane.
Compact Diverter Gate
Fit the short JIS profile barrel into a narrow conveyor frame to push lightweight packages off the main belt.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X25-10S the Right Cylinder?
Size this 50 mm bore against its neighbours: a 40 mm bore gives 628 N push at 0.5 MPa, while a 63 mm bore yields 1559 N. The adjustable stroke is ideal when you want one shared spare across slightly different stroke variants or need to fine-tune the extend end position on the machine. The JSIJ series supports Basic, FA, LB, TC, TCM1, and TCM2 mounts. The -S magnet allows CMSE/DMSE sensors to drop into the profile grooves. For any stroke at or above 300 mm, add an external guide rail to prevent side-load wear on the rod seal.
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 JSIJ50X25-10S 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. The air port size is G1/4.
The 25 mm nominal stroke is the maximum. The external stop screw lets you shorten the extend stroke by up to 10 mm on-site, yielding a usable extend range of 15 to 25 mm. The retract end remains fixed.
