Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-100S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-100S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 500mm 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 JSIJ50X500-100S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for tasks that demand exact end-position tuning. The external stop screw provides a 100 mm adjustment window, meaning the usable extend stroke can be fine-tuned anywhere from 400 mm up to the 500 mm maximum right on the floor without swapping the actuator. Because the retract end remains fixed, only the forward motion gets shortened. The extruded hard-anodized aluminium barrel omits tie rods entirely, making the body noticeably shorter and more compact than a same-bore ISO 15552 unit.
This -S variant carries a built-in piston magnet for CMSE or DMSE reed and electronic switches that drop directly into the side grooves. It handles a safe working load of roughly 589 N, which equates to lifting about 50 kg vertically with a 2:1 safety margin. Air enters via a G1/4 port, driving the 20 mm rod at speeds of 30-800 mm/s. Note that the adjustable air cushions only decelerate the piston near the ends; to prevent drift on air loss, fit an external rod lock or pilot-operated check valve.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-100S Is Used
Divert Gate Tuning
Adjusts the extend stroke from 400 to 500 mm on-site to perfectly set the divert gate distance for varying package sizes on the line.
Lifting Platform Stop
Lifts a 50 kg vertical load using the 982 N push force, with the external adjuster allowing precise height stops without reprogramming the PLC.
Pallet Positioning
Uses the 100 mm shortening window to fine-tune the extend end position for different pallet widths before triggering the CMSE sensor.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-100S the Right Cylinder?
When sizing this actuator, compare it against neighbouring bores: a 40 mm bore yields 628 N of push at 0.5 MPa, while a 63 mm bore jumps to 1559 N, so the 50 mm at 982 N is the sweet spot for mid-range duties. The 100 mm adjustable window is especially useful when you want a single spare part to cover several stroke variants or need on-site end-position tuning. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this is a 500 mm stroke, always support the load with an external guide to prevent rod bending and excessive side loading. The -S magnet allows precise position sensing, but remember a plain cylinder cannot hold a load without live air.

- ✓ 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 JSIJ50X500-100S 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. The air port size is G1/4.
The nominal stroke is 500 mm, which is the maximum extend length. The external adjuster lets you shorten the forward stroke by up to 100 mm on-site, giving a usable extend range of 400-500 mm. The retract end is fixed, and the stop screw sets the end position but does not lock the load.
