Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X200-20
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X200-20 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 200mm 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 JSIJ63X200-20
The hard-anodized aluminum barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 unit. It operates with a G3/8 port, a 20 mm piston rod, and adjustable 29 mm air cushions at both ends.
The external stop screw lets you shorten the usable extend stroke from the 200 mm maximum down to 180 mm without swapping the cylinder, while the retract end remains fixed. Note that this plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor; adding the -S variant enables switch readiness.

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 JSIJ63X200-20 Is Used
End-Position Trimming
Dial in the exact clamping contact point on machining fixtures by shortening the extend stroke up to 20 mm on-site.
Transfer Diverter
Actuate a routing gate where the full 200 mm stroke provides clearance but the physical stop needs precise 180 mm positioning.
Shared Spare Inventory
Keep one cylinder on the shelf and adjust the extend window to replace units needing slightly shorter strokes on the packaging line.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X200-20 the Right Cylinder?
The 20 mm adjustable window is ideal for sharing a single spare across multiple stroke variants or dialing in a final end position on the machine. Mounting choices include FA, LB, TC, TCM1, and TCM2 brackets. Because the 200 mm stroke is relatively short, side-load stress is minimal, but always guide the load for any stroke length exceeding 300 mm. Remember this non-magnetic version cannot support position sensing.
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 JSIJ63X200-20 FAQ
It uses a G3/8 port, an M18x1.5 rod thread, and 29 mm adjustable cushions. Operating speed ranges from 30-800 mm/s.
The external adjuster allows you to shorten the extend stroke by up to 20 mm on-site, meaning the usable extend range is 180-200 mm (the 200 mm nominal stroke is the maximum). The retract end is fixed. This stop only sets the end position and decelerates the load; it does not hold the load on air loss, so use an external rod lock or pilot-operated check valve for holding.
