Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-75
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-75 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 500mm stroke, G3/8 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 JSIJ63~80 Adjustable Cylinder JSIJ80X500-75
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings heavy-duty actuation into a compact footprint that is noticeably shorter than a same-bore ISO 15552 unit. The hard-anodized aluminium barrel keeps the assembly light, and the G3/8 air port matches the bore size. A 25 mm piston rod and M22x1.5 rod thread handle the high thrust, while 29 mm adjustable air cushions at each end absorb end-of-stroke impact.
The -75 code means an external stop screw lets you shorten the extend stroke on-site by up to 75 mm, giving a usable extend range of 425 to 500 mm without changing the cylinder itself. This on-site tuning is perfect for dialing in exact end positions. Based on the 0.5 MPa push rating, it handles about 1508 N of real work safely, which equates to lifting roughly 128 kg vertically. Note that this SKU lacks a magnet, so it cannot take CMSE or DMSE sensors; the -S variant is required for position detection.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-75 Is Used
Transfer Diverter
Dial in the exact push distance on a sorting line by adjusting the extend stroke up to 75 mm to deflect varying package sizes without swapping cylinders.
Press Clamping
Use the 2513 N thrust to hold parts in a fixture, tweaking the final clamping position on-site to accommodate different material thicknesses.
Pallet Stopper
Act as a heavy-duty stop gate for pallets, using the adjustable end position to handle different pallet depths while benefiting from the compact JIS profile.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X500-75 the Right Cylinder?
When sizing, the 63 mm bore offers 1559 N push at 0.5 MPa, while the 100 mm bore jumps to 3927 N, so this 80 mm model sits perfectly in the middle for medium-heavy loads. The adjustable stroke is a major advantage when you need to fine-tune the extend end position on-site or want a single spare cylinder to cover several stroke length variants. JSIJ mounting options include Basic, 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. Remember that a plain cylinder does not hold load on air loss; use an external rod lock or pilot-operated check valve for vertical holding.
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 JSIJ63~80 Adjustable Cylinder JSIJ80X500-75 FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull. At 0.7 MPa it provides 3518 N push and 3175 N pull. The theoretical maximum force is 513 kgf at 1.0 MPa. The cylinder features a G3/8 port and a 25 mm rod.
The nominal 500 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 75 mm on-site, giving a usable extend range of 425 to 500 mm. The retract end is fixed. This stop sets the end position but does not lock the load.
