Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-50
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-50 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 JSIJ50X500-50
Delivering 982 N of push force at 0.5 MPa, this JIS-standard profile cylinder is built for applications needing on-site end-position tuning. Its hard-anodized aluminum barrel omits tie rods, making the body noticeably shorter and more compact than a same-bore ISO 15552 unit. The G1/4 port and M18x1.5 rod thread keep pneumatic and mounting integration straightforward.
The external adjuster lets you shorten the extend stroke by up to 50 mm on site, giving a usable range of 450-500 mm without swapping the cylinder. It handles about 589 N of real work safely, translating to roughly 50 kg lifted vertically with a 2:1 margin. Note that this SKU lacks a magnet and cannot take CMSE/DMSE sensors; for the switch-ready version, specify the -S suffix.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-50 Is Used
Transfer Push-Off Tuning
Dial in the exact 450-500 mm push-off distance for varying product lengths on a packaging line without changing the cylinder.
Adjustable Press Stroke
Fine-tune the down-stroke end position on a light 50 kg assembly press to accommodate different material thicknesses on site.
Multi-Position Diverting
Use the 50 mm window to set intermediate extend stops for sorting items into different palletizing lanes.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-50 the Right Cylinder?
When sizing, the 50 mm bore sits between the 40 mm (628 N push at 0.5 MPa) and the 63 mm (1559 N push at 0.5 MPa). Choose this adjustable model when you need to fine-tune the extend endpoint across multiple stations or want a shared spare for slightly different 450-500 mm stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because the 500 mm stroke is long, always use external guides to prevent rod bending and side loads. Remember that the adjuster sets position but does not lock the load—add an external rod lock or pilot-operated check valve if you need to hold a vertical load against air loss.
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 JSIJ50X500-50 FAQ
This 50 mm bore cylinder uses a G1/4 port. It generates 982 N push and 825 N pull at 0.5 MPa, 1374 N push and 1154 N pull at 0.7 MPa, with a theoretical maximum of 200 kgf at 1.0 MPa.
The nominal 500 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 50 mm on site, yielding a usable range of 450-500 mm. The retract end remains fixed, and the cushion only decelerates—it does not lock the load.
