Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X25-10
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X25-10 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 25mm 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 JSIJ50X25-10
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is shorter and more compact than a same-bore ISO 15552 unit. The hard-anodized aluminium barrel keeps the build light without external tie rods. It handles about 589 N of real work safely, which means lifting roughly 50 kg vertically with a 2:1 margin.
The external adjuster lets you shorten the extend stroke on-site by up to 10 mm, giving a usable range of 15 to 25 mm for fine-tuning the end position without swapping the cylinder. Air connects via a G1/4 port. This base SKU lacks a magnet, so it cannot accept CMSE or DMSE sensors.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X25-10 Is Used
Clamp Stroke Tuning
Dial in the exact 15 to 25 mm extend reach on a machining fixture to compensate for part tolerance variations without remounting the actuator.
Short Press Operation
Provide a precise, short downward pressing action for light assembly tasks, using the stop screw to set the final depth safely.
Spacer Insertion
Push a small component into a slot exactly 20 mm deep, adjusting the stroke on-site by up to 10 mm to avoid over-travel damage.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X25-10 the Right Cylinder?
When sizing this unit, the neighbouring 40 mm bore yields 628 N push at 0.5 MPa, while the 63 mm bore steps up to 1559 N, letting you dial in the exact force class. The 10 mm adjuster is ideal for sharing a spare across slight stroke variants or finalizing end positions during machine commissioning. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this is a non-magnetized model, you must select an -S version if you require position sensing. For any stroke over 300 mm, always use a guide to prevent side-load damage.
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 JSIJ50X25-10 FAQ
This 50 mm bore cylinder pushes 982 N and pulls 825 N at 0.5 MPa. At 0.7 MPa it pushes 1374 N and pulls 1154 N. The theoretical maximum force is 200 kgf at 1.0 MPa. It uses a G1/4 air port.
The nominal extend stroke is 25 mm. An external stop screw lets you shorten that extend travel on-site by up to 10 mm, yielding a usable range of 15 to 25 mm. The retract end is fixed. This mechanism sets the end position and does not lock the load.
