Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X50-10
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X50-10 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 50mm 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 JSIJ50X50-10
Generating 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder brings compact power to tight assemblies. The hard-anodized aluminum barrel is noticeably shorter than an equivalent ISO 15552 unit. It handles a safe working load of about 589 N, which translates to lifting roughly 50 kg vertically with a 2:1 margin.
A built-in external adjuster lets you shorten the extend stroke by up to 10 mm on-site, giving a usable range of 40 to 50 mm without swapping the cylinder. The retract end remains fixed. This double-acting unit uses a G1/4 port and adjustable air cushions. Because this SKU lacks a magnet, it cannot take a CMSE or DMSE sensor.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X50-10 Is Used
Clamp Position Tuning
Dial in the exact 40 to 50 mm extend reach on a machining fixture to accommodate varying part tolerances without remounting the actuator.
Transfer Gate Stop
Set a precise product stop position on a packaging line, using the adjuster to shorten the stroke exactly where the goods need to halt.
Compact Vertical Lift
Lift approximately 50 kg of stock vertically in a tight bay, benefiting from the shortened JIS profile where standard ISO 15552 lengths will not fit.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X50-10 the Right Cylinder?
This 50 mm bore bridges the gap between the 40 mm (628 N push at 0.5 MPa) and 63 mm (1559 N) sizes. The 10 mm extend-shortening window is ideal for fine-tuning end positions on-site or standardizing a shared spare across slightly different stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. For any stroke over 300 mm, use a guide to prevent side-load damage. To hold a load securely on air loss, add an external rod lock or pilot-operated check valve, as the cushion only decelerates.
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 JSIJ50X50-10 FAQ
At 0.5 MPa it delivers 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. This model uses a G1/4 air port.
The external adjuster lets you shorten the extend stroke by up to 10 mm on-site. The nominal 50 mm stroke is the maximum, giving a usable extend range of 40 to 50 mm. The retract end is fixed, and this stop only sets the end position rather than locking the load.
