Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-50S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-50S 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 JSIJ50X700-50S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for applications that need exact end-position tuning on site. Its hard-anodized aluminum extruded barrel makes it shorter and more compact than a same-bore ISO 15552 unit. The external adjuster lets you shorten the extend stroke by up to 50 mm, giving a usable range of 650 to 700 mm without swapping the cylinder.
This -S variant includes a piston magnet for CMSE/DMSE sensors that drop directly into the side grooves. It handles about 589 N of safe working load, which is roughly 50 kg lifted vertically with a 2:1 margin. Air connects via a G1/4 port, and adjustable air cushions of 20.5 mm decelerate the piston at both ends. Note that the cushion only slows the load; for holding a load on air loss, fit an external rod lock or pilot-operated check valve.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-50S Is Used
Conveyor Diverter Tuning
Fine-tune the 650 to 700 mm extend stop on site to perfectly align a diverter gate with varying product widths without machining new mounts.
Vertical Lift Positioning
Lift loads up to 50 kg and use the external adjuster to set the exact raise height, compensating for varying package thicknesses on the fly.
Long-Reach Clamping
Clamp large workpieces at a 700 mm reach, dialing back the stroke by 50 mm if the part geometry changes to avoid over-travel damage.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-50S the Right Cylinder?
When sizing this unit, the 40 mm bore offers 628 N push at 0.5 MPa, while the 63 mm bore steps up to 1559 N if you need more force. The JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The built-in magnet (-S) supports CMSE/DMSE switches for position confirmation. Because the 700 mm stroke is long, always use external guides to prevent rod bending and side-load damage. The adjustable 50 mm window is perfect for sharing one spare across multiple stroke variants or fine-tuning the final stop position on the machine.

- ✓ 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 JSIJ50X700-50S 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 700 mm stroke is the maximum. The external stop screw lets you shorten the extend stroke by up to 50 mm on site, giving a usable extend range of 650 to 700 mm. The retract end is fixed, and the stop sets position only, not a load lock.
