Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X900-10S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X900-10S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 900mm 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 JSIJ50X900-10S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder packs serious muscle into a body that is shorter and more compact than a same-bore ISO 15552 unit. The hard-anodized aluminium extruded barrel contains no external tie rods, keeping the overall envelope clean. Because the usable extend stroke spans 890 to 900 mm, you can fine-tune the end position on site without swapping the actuator.
The external stop screw provides a 10 mm shortening window, letting you dial in the exact extend endpoint while the retract end stays fixed. A built-in piston magnet (-S) supports CMSE and DMSE reed or electronic switches that drop directly into the side grooves. Operating on a G1/4 port, it handles a safe working load of roughly 589 N, which translates to lifting about 50 kg vertically with a 2:1 safety margin. Note that the adjustable cushion only decelerates the piston; an external rod lock or pilot-operated check valve is required to hold a load on air loss.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X900-10S Is Used
Long-Reach Diverting
Pushes packages across a wide transfer belt, using the 10 mm on-site adjuster to perfectly match the diverter end position without changing the actuator.
Vertical Material Lift
Lifts roughly 50 kg of stacked goods vertically, relying on the 982 N push force at 0.5 MPa while an external guide absorbs the long 900 mm rod side-load.
Adjustable Length Stopper
Acts as a hard mechanical stop for varying product lengths on a packing line, trimming the extend stroke by up to 10 mm to accommodate different box sizes.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X900-10S the Right Cylinder?
When sizing this actuator, the 50 mm bore sits neatly between the 40 mm class (628 N push at 0.5 MPa) and the 63 mm class (1559 N push at 0.5 MPa), giving you a solid 982 N baseline. The 10 mm extend-shortening window is especially useful when you need to share a spare cylinder across slightly different stroke variants or trim a long 900 mm reach on site. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The integrated -S magnet allows for precise end-of-stroke sensing. Because the 900 mm stroke is quite long, always support the rod against side loads with an external guide to prevent bending and premature seal wear.

- ✓ 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 JSIJ50X900-10S FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it provides 1374 N push and 1154 N pull. The theoretical maximum force is 200 kgf at 1.0 MPa. It uses a G1/4 port and features a 20 mm piston rod.
The nominal 900 mm stroke is the maximum length. An external stop screw lets you shorten the extend stroke by up to 10 mm on site, giving a usable extend range of 890 to 900 mm. The retract end remains fixed, and this mechanism sets the end position rather than locking the load.
