Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-20
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-20 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 JSIJ50X500-20
Generating 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for long-reach actuation where exact end-positioning matters. The hard-anodized aluminium barrel keeps the total length shorter than a same-bore ISO 15552 unit, saving valuable machine space. A G1/4 port feeds the double-acting single rod, and the adjustable air cushions absorb kinetic energy at both ends.
The external stop screw lets you trim the extend stroke by up to 20 mm on site, giving a usable forward travel of 480-500 mm without swapping the cylinder. Factoring in a 60% safety margin, it handles about 589 N of real work, which means you can vertically lift roughly 50 kg. Note this plain SKU lacks a magnet and cannot take a CMSE/DMSE sensor; for a held load you must add an external rod lock, as the cushion only decelerates.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-20 Is Used
Long-Reach Diverting
Pushes packages across a wide belt, using the 20 mm adjuster to dial in the exact contact point without moving the cylinder mounts.
High-Bay Ejection
Extends 500 mm to knock stored cartons off a shelf, relying on adjustable cushions to stop the 50 mm piston smoothly at the far end.
Long-Stroke Gauging
Feeds a probe out to test part dimensions, trimming the extend stroke on site to compensate for varying fixture heights.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-20 the Right Cylinder?
When sizing, the 63 mm bore steps up to 1559 N push at 0.5 MPa, while the 40 mm bore drops to 628 N, so the 50 mm sits squarely in the mid-range. The 20 mm adjustable window is highly useful when you need to fine-tune a distant end position or want one shared spare across several stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the stroke is 500 mm, you must support the load with external guides to prevent rod bending and side-load damage. This non-magnetic model cannot accept position sensors; choose the -S variant if you need CMSE or DMSE switches.
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 JSIJ50X500-20 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 50 mm bore unit uses a G1/4 air port and features a 20 mm adjustable air cushion at each end.
An external stop screw lets you shorten the extend stroke by up to 20 mm on site, giving a usable forward travel of 480-500 mm. The nominal 500 mm stroke remains the maximum, and the retract end is fixed. This mechanism only sets the end position; it does not lock the load on air loss.
