Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-100S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-100S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 700mm 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 JSIJ50X700-100S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder features an external adjuster that shortens the extend stroke on-site by up to 100 mm. The nominal 700 mm stroke remains the maximum travel, yielding a usable 600 to 700 mm extend window, while the retract end stays fixed. Because the hard-anodized aluminum extrusion omits exposed rods, the overall body is noticeably shorter and more compact than a same-bore ISO 15552 unit.
The built-in -S piston magnet accepts CMSE or DMSE reed and electronic switches that drop directly into the side grooves for position sensing. Operating on a G1/4 port with a 20 mm rod and M18x1.5 thread, it handles a safe working load of roughly 589 N, which translates to lifting about 50 kg vertically with a 2:1 margin. The adjustable air cushions at both ends decelerate the payload smoothly, though an external rod lock or pilot-operated check valve is required if you need to hold a load securely on air loss.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-100S Is Used
Long-Reach Diversion
Pushes packages across a wide sorting belt with a 700 mm extend stroke, fine-tuned down by 100 mm on-site to hit a new lane position perfectly.
Vertical Material Lift
Raises a 50 kg tote to an upper tier using the 2:1 safety margin, relying on the external adjuster to set the exact raise height without reprogramming.
Adjustable Sealing Press
Closes a carton flap at varying depths, using the 100 mm shorten window to accommodate different box sizes on a shared 50 mm bore platform.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-100S the Right Cylinder?
When sizing this actuator, the neighboring 40 mm bore offers 628 N push at 0.5 MPa for lighter duties, while the 63 mm bore steps up to 1559 N if your payload exceeds the 50 mm capacity. The 100 mm adjustable window is invaluable for fine-tuning the extend end position on-site without swapping the cylinder, letting you standardize one 700 mm spare across multiple stroke variants. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Because the 700 mm stroke is quite long, always use an external guide rail to prevent rod bending and side-load damage. The -S magnet enables precise end-of-stroke detection using CMSE/DMSE sensors.

- ✓ 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 JSIJ50X700-100S FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it delivers 1374 N push and 1154 N pull. The theoretical maximum force is 200 kgf at 1.0 MPa. This 50 mm bore unit uses a G1/4 air port, a 20 mm rod, and an M18x1.5 rod-end thread.
The external stop screw lets you shorten the extend stroke by up to 100 mm on-site. With a nominal 700 mm maximum stroke, your usable extend range is 600 to 700 mm. The retract end is fixed, and this mechanism only sets the end position—it is not a load lock.
