Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X900-75
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X900-75 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 900mm 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 JSIJ80X900-75
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore pneumatic actuator brings heavy-duty performance to applications needing exact end-position tuning. It handles about 1508 N of real work safely, which translates to roughly 128 kg lifted vertically with a 2:1 margin. The hard-anodized aluminium profile barrel keeps the total envelope more compact than a same-bore ISO 15552 cylinder, and the G3/8 air port matches the 80 mm bore standard.
An external stop screw lets you shorten the extend stroke on-site by up to 75 mm, giving a usable forward range of 825 to 900 mm while the retract end remains fixed. This on-site adjustability means you can fine-tune the stroke without swapping the cylinder, and it lets you standardize one spare across multiple stroke variants. The piston rod measures 25 mm with an M22x1.5 thread, and adjustable 29 mm air cushions decelerate the load at both ends. Because this SKU lacks the -S magnet option, it cannot accept CMSE or DMSE sensors.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X900-75 Is Used
Transfer Line Diverter
Fine-tune the 825 to 900 mm extend reach on-site to push heavy pallets between parallel conveyor belts without changing the cylinder mount.
Long-Reach Pusher
Use the 25 mm rod to shift heavy cartons across a 900 mm packing table, adjusting the final stop position by up to 75 mm for varied box sizes.
Material Lowering Arm
Lower assemblies into fixtures using the 2513 N push force, relying on the 29 mm cushions to decelerate the drop over the long travel distance.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X900-75 the Right Cylinder?
When sizing this actuator, look at the neighbouring bores: a 63 mm bore gives 1559 N push at 0.5 MPa, while a 100 mm bore yields 3927 N, so the 80 mm sits perfectly in the middle for medium-heavy loads. The adjustable stroke is ideal for on-site end-position tuning or keeping a shared spare across stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because the 900 mm stroke is quite long, you must support the load with external guides to prevent rod bending and side-load damage. A plain cylinder drifts on air loss, so use an external rod lock or pilot-operated check valve if you need to hold a load securely.
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 JSIJ80X900-75 FAQ
This 80 mm bore cylinder pushes 2513 N and pulls 2268 N at 0.5 MPa. 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 air port and features a 25 mm piston rod with an M22x1.5 thread.
The nominal 900 mm extend stroke is the maximum travel. An external stop screw lets you shorten that forward stroke on-site by up to 75 mm, yielding a usable extend range of 825 to 900 mm. The retract end is fixed, and this stop mechanism only sets the end position—it does not lock or hold the load.
