Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X80-10
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X80-10 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 80mm 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 JSIJ50X80-10
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder integrates an external adjuster that shortens the extend stroke by up to 10 mm on site. The nominal 80 mm travel remains the maximum, yielding a usable extend range of 70 to 80 mm, while the retract end stays fixed. You can fine-tune the end position mechanically without swapping the whole unit.
Built with an extruded hard-anodized aluminum barrel, the body is shorter and more compact than an ISO 15552 cylinder of the same bore. It handles about 589 N of real work safely, which translates to roughly 50 kg lifted vertically with a 2:1 margin. Pneumatic connections use a G1/4 port, and the rod end features an M18x1.5 thread.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X80-10 Is Used
Press Fit Dialing
Use the 10 mm extend window to micro-adjust insertion depth of light bearings on an assembly line without changing the cylinder.
Transfer Stopper Tuning
Set the exact 70 to 80 mm pop-up height for a pneumatic stop gate to accommodate varying package sizes on the fly.
Sealing Head Setup
Fine-tune the downstroke end position for a heat-sealing head to compensate for material thickness variations.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X80-10 the Right Cylinder?
Size this 50 mm bore against its neighbors: a 40 mm bore yields 628 N push at 0.5 MPa, whereas a 63 mm bore jumps to 1559 N. The adjustable stroke shines when you need to dial in a precise end position across multiple machines or want a shared spare for slightly different stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this specific SKU lacks the -S suffix, it cannot accept a magnetic sensor; choose the -S variant for CMSE or DMSE switches. For any stroke over 300 mm, always guide the load 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 JSIJ50X80-10 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 external stop screw lets you shorten the extend stroke by up to 10 mm on site, giving a usable extend range of 70 to 80 mm. The nominal 80 mm stroke is the maximum, and the retract end is fixed. This stop sets the end position and is not a load lock.
