Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-75
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-75 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 275mm 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 JSIJ80X275-75
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder features an external adjuster that shortens the extend stroke on-site by up to 75 mm. The hard-anodized aluminium barrel omits tie rods, making the overall body shorter and more compact than a same-bore ISO 15552 unit. It handles about 1508 N of real work safely, which translates to roughly 128 kg lifted vertically with a 2:1 margin. Air connects via a G3/8 port, driving a 25 mm piston rod with M22x1.5 threads.
With a nominal 275 mm stroke, the usable extend range is 200-275 mm because the retract end remains fixed. The external stop screw lets you fine-tune the end position without swapping the cylinder, while the 29 mm adjustable air cushions at both ends decelerate the load smoothly. Note that this SKU lacks a magnet and cannot take CMSE/DMSE sensors; for that you need the -S variant. A plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you must hold a load.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-75 Is Used
Press Stroke Tuning
Dial in the exact 200-275 mm extend reach on a light assembly press without machining new spacers, relying on 3518 N of thrust at 0.7 MPa.
Variable Transfer Stops
Act as an adjustable lane diverter on a conveyor line, shortening the extend stroke by up to 75 mm to accommodate different product widths on the fly.
Pallet Positioning
Push pallets into a wrapping station with 2513 N of force at 0.5 MPa, fine-tuning the stop point to match varying pallet overhangs.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-75 the Right Cylinder?
When sizing this 80 mm bore, the neighbouring 63 mm bore yields 1559 N push at 0.5 MPa, whereas stepping up to the 100 mm bore provides 3927 N, letting you bracket your force needs precisely. The 75 mm adjustable window is ideal when you need to share one spare cylinder across several stroke variants or dial in a final end position on the machine. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because the 275 mm stroke exceeds 300 mm only slightly, guide any side loads to prevent rod bending. This non-magnet version cannot accept position sensors; specify the -S option if your control system requires 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 JSIJ63~80 Adjustable Cylinder JSIJ80X275-75 FAQ
At 0.5 MPa it pushes 2513 N and pulls 2268 N; at 0.7 MPa it pushes 3518 N and pulls 3175 N. The theoretical maximum force is 513 kgf at 1.0 MPa. It uses a G3/8 port, a 25 mm rod with M22x1.5 thread, and 29 mm adjustable cushions at both ends.
The nominal 275 mm stroke is the maximum extend length. The external adjuster lets you shorten that extend stroke by up to 75 mm on-site, giving a usable range of 200-275 mm. The retract end is fixed, and the adjuster sets the end position but does not lock the load.
