Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X400-30S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X400-30S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 400mm 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 JSIJ80X400-30S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder is built for heavy-duty positioning. The extruded hard-anodized aluminium barrel omits tie rods, making the overall body shorter and more compact than a same-bore ISO 15552 unit. A G3/8 port feeds the 25 mm rod, yielding a practical working load of about 1508 N, which equates to lifting nearly 128 kg vertically with a 2:1 safety margin.
The -30 code means an external stop screw lets you shorten the extend stroke on-site by up to 30 mm, giving a usable range of 370-400 mm while the retract end stays fixed. Because this is an -S SKU, a built-in piston magnet pairs directly with CMSE or DMSE sensors that drop into the barrel grooves. Note that the adjustable air cushions only decelerate the load near stroke end; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve for true load holding.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X400-30S Is Used
Package Divert Stroke Tuning
Dial in the exact 370-400 mm extend push-off distance on a sorting line using the external adjuster, avoiding mechanical clashes with varying carton sizes.
Vertical Pallet Lift
Lifts roughly 128 kg vertically using the 2513 N push force, with the 30 mm window allowing precise height calibration at the upper stop without reworking mounts.
Press Clamping Stop
Holds a workpiece with a safe working load near 1508 N, using the adjustable stroke to set the exact clamping position for different material thicknesses.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X400-30S the Right Cylinder?
Size this 80 mm bore against its neighbours: a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore jumps to 3927 N. The adjustable stroke is ideal when you need to fine-tune the extend end position without swapping the cylinder, or when consolidating spare parts across similar stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The -S suffix ensures you have the magnet for CMSE/DMSE position sensing. Because the 400 mm stroke creates leverage, always use an external guide to prevent rod bending and absorb 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 JSIJ63~80 Adjustable Cylinder JSIJ80X400-30S FAQ
This 80 mm bore cylinder uses a G3/8 port. 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 force of 513 kgf at 1.0 MPa.
The nominal 400 mm stroke is the maximum length. An external stop screw lets you shorten the extend stroke on-site by up to 30 mm, giving a usable extend range of 370-400 mm. The retract end remains fixed, and the cushion only decelerates the load without holding it.
