Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X600-20
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X600-20 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 600mm 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 JSIJ63X600-20
Its extruded hard-anodized aluminium barrel omits tie rods entirely, making the overall body shorter than a same-bore ISO 15552 unit.
The -20 code means an external adjuster can shorten the extend stroke on-site by up to 20 mm, giving a usable 580-600 mm range while the retract end stays fixed. You fine-tune the end position without swapping the cylinder itself. Note this SKU lacks a magnet and cannot take a CMSE/DMSE sensor; for the 600 mm stroke, fit external guides to prevent rod bending under side loads.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|

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 JSIJ63X600-20 Is Used
Long-Reach Transfer
Pushes parts down a 600 mm conveyor lane, using the 20 mm adjuster to dial in the exact push-off distance on-site.
Pallet Positioning
Indexes pallets with a 580-600 mm stroke, allowing operators to fine-tune the stop point without changing the hardware.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X600-20 the Right Cylinder?
The adjustable window shines when you need to dial in a final end position on-site or want a shared spare across slight stroke variants. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a 600 mm stroke, always support the load with external guides to avoid rod bending. This non-magnet SKU cannot host a sensor; add the -S variant for CMSE/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 JSIJ63X600-20 FAQ
It uses a G3/8 port.
The external adjuster lets you shorten the extend stroke by up to 20 mm on-site, yielding a 580-600 mm usable range while the retract end remains fixed. This mechanism only sets the end position; it does not hold the load on air loss. For load holding, use an external rod lock or pilot-operated check valve.
