Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-100
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-100 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 JSIJ50X500-100
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder saves machine space by being shorter than a same-bore ISO 15552 unit. The hard-anodized aluminium barrel keeps the assembly light while handling about 589 N of real work, which translates to lifting roughly 50 kg vertically with a 2:1 safety margin. Air connects via a G1/4 port, and the M18x1.5 rod end threads directly into your tooling.
The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, giving a usable forward range of 400 to 500 mm without changing the cylinder itself. This on-site tuning is ideal for dialing in exact end positions across multiple stations. Because this SKU lacks the -S magnet option, it cannot accept CMSE or DMSE sensors. Note that a plain cylinder drifts on air loss; the adjustable cushion only decelerates near the end, so fit an external rod lock for held loads.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-100 Is Used
Lift Station Calibration
Dial in the exact upper lift height of a 50 kg workpiece carrier on the fly using the 100 mm extend window, ensuring precise placement without machining new spacers.
Variable Transfer Push
Adjust the push-off distance for different carton widths on a packaging line, shortening the 500 mm stroke as needed to accommodate varied product sizes.
Long Reach Forming
Extend a forming tool deep into a machine bed, using the hard-anodized profile barrel and adjustable end cushion to decelerate the 500 mm travel smoothly.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-100 the Right Cylinder?
When sizing this unit, the adjacent 40 mm bore offers 628 N push at 0.5 MPa for lighter duties, while the 63 mm bore steps up to 1559 N if your payload increases. The 100 mm adjuster window is particularly useful when you want one shared spare cylinder that can cover several slightly different stroke lengths on-site. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Since the 500 mm stroke is quite long, always support the tooling with an external guide to prevent rod bending and excessive side loads.
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 JSIJ50X500-100 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. This 50 mm bore unit uses a G1/4 air port and features a 20 mm adjustable air cushion at each end.
The nominal 500 mm stroke is the maximum forward travel. The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, providing a usable range of 400 to 500 mm. The retract end remains fixed, and this stop mechanism only sets the end position; it does not lock the load.
