Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X500-10
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X500-10 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm 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 JSIJ63X500-10
The extruded hard-anodized aluminium barrel leaves out external rods, making the overall body shorter and more compact than an equivalent ISO 15552 cylinder of the same bore. A G3/8 port feeds the double-acting double-rod system, while adjustable air cushions of 29 mm at each end absorb end-of-stroke impacts.
The external adjuster lets you trim the extend stroke on-site by up to 10 mm, giving a usable range of 490 to 500 mm without swapping the cylinder. This on-site tuning is ideal for sharing spares across stroke variants or fine-tuning end positions. Note this SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |

| Max (@1.0 MPa) | 286 kgf | |
JSIJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X500-10 Is Used
Conveyor Diverter Tuning
Fine-tune the 10 mm extend window on-site to perfectly align a diverter gate without remounting the entire actuator assembly.
Long-Reach Push Arm
Use the 500 mm stroke to clear wide pallet lanes, adjusting the final end position by a few millimetres to match varying load widths.
Shared Spare Actuator
Keep one cylinder in stock and dial the stop screw in by up to 10 mm to cover multiple similar machines with slightly different extend lengths.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X500-10 the Right Cylinder?
The 10 mm adjustable window is highly useful when you need to synchronise multiple end positions or keep a shared spare across slightly different stroke variants. JSIJ mounting choices include Basic, FA, LB, TC, TCM1, and TCM2. Because the 500 mm stroke is long, always use an external guide to prevent rod bending and manage side loads. A plain cylinder cannot hold a load on air loss, so fit an external rod lock or pilot-operated check valve if you need strict positioning.
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 JSIJ63X500-10 FAQ
This 63 mm bore cylinder uses a G3/8 port. The theoretical maximum force is 318 kgf at 1.0 MPa.
The -10 code means an external stop screw lets you shorten the extend stroke by up to 10 mm on-site. The nominal 500 mm stroke is the maximum, giving a usable extend range of 490 to 500 mm, while the retract end remains fixed. The stop sets the end position but does not lock the load.
