Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X160-20
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X160-20 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 160mm 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 JSIJ63X160-20
Its hard-anodized aluminium barrel is shorter than a same-bore ISO 15552 unit, saving machine footprint without losing strength.
The -20 code defines an external adjuster that shortens the extend stroke on-site by up to 20 mm, giving a usable 140-160 mm end-position window while the retract end stays fixed. You can fine-tune the stop without swapping the cylinder. Note this plain SKU lacks a magnet and cannot take CMSE/DMSE sensors.

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 JSIJ63X160-20 Is Used
Press Fit Tuning
Dial in the exact 140-160 mm extend position for seating bearings without machining custom spacers.
Variable Transfer Stop
Adjust the extend stop on-site to handle different package lengths on a shared production line.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X160-20 the Right Cylinder?
The adjustable stroke shines when you need to dial in a precise end position on-site or want a single spare part covering 140-160 mm travel variants. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because the 160 mm stroke exceeds 300 mm, always guide the load to prevent rod side-loading. For position feedback you must select the -S magnet version, as this base model cannot accept a sensor.
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 JSIJ63X160-20 FAQ
At 0.5 MPa it pushes 1559 N and pulls 1402 N. At 0.7 MPa it pushes 2182 N and pulls 1962 N. The theoretical maximum is 318 kgf at 1.0 MPa. It uses a G3/8 port with an M18x1.5 rod thread and 29 mm adjustable air cushions at both ends.
The nominal 160 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 20 mm on-site, yielding a usable 140-160 mm range. The retract end is fixed. This stop only sets the end position; it does not lock the load, so use an external rod lock or pilot-operated check valve for holding.
