Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X900-20
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X900-20 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 JSIJ80X900-20
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore pneumatic unit handles about 1508 N of real work, roughly 128 kg lifted vertically. The G3/8 ported body uses an extruded hard-anodized aluminum profile, making it shorter and more compact than a same-bore ISO 15552 cylinder.
As an adjustable-stroke JIS build, it features an external stop screw that lets you shorten the extend stroke on-site by up to 20 mm, giving a usable range of 880-900 mm without changing the cylinder itself. The retract end remains fixed, and the adjustable air cushions provide 29 mm of deceleration at each end. This SKU has no magnet and cannot take a CMSE or DMSE sensor.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X900-20 Is Used
Long-Transfer Push-Off
Pushes pallets off a long conveyor line, using the 20 mm adjuster to dial in the exact kick distance without repositioning the hard stops.
High-Reach Stowage Actuator
Extends goods into deep storage racks, relying on the 29 mm adjustable cushions to decelerate the heavy 900 mm travel smoothly.
Material Discharge Arm
Drives a long discharge arm on a packaging line, trimming the extend end position by up to 20 mm to accommodate varying container widths.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X900-20 the Right Cylinder?
When sizing this 80 mm bore, stepping down to a 63 mm bore yields 1559 N push at 0.5 MPa, while stepping up to a 100 mm bore provides 3927 N. The -20 mm adjuster window is ideal for fine-tuning the end position on-site or sharing a spare across stroke variants. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the stroke is 900 mm, you must support the load with external guides to prevent rod bending and side-load damage. Note that a plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve for held 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 JSIJ63~80 Adjustable Cylinder JSIJ80X900-20 FAQ
This 80 mm bore cylinder uses a G3/8 port and a 25 mm rod. It generates 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push and 3175 N pull at 0.7 MPa, with a theoretical maximum of 513 kgf at 1.0 MPa.
The nominal 900 mm extend stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 20 mm, yielding a usable range of 880-900 mm. The retract end is fixed, and this stop only sets the end position—it is not a load lock.
