Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X150-50
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X150-50 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 150mm 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 JSIJ63X150-50
The hard-anodized aluminum barrel keeps the assembly light, while the G3/8 port supplies ample air volume for smooth operation. An external stop screw lets you fine-tune the extend position on-site without swapping the cylinder.
The -50 code defines a 50 mm adjustment window, meaning the usable extend stroke can be shortened from the 150 mm maximum down to 100 mm on-site, with the retract end remaining fixed. This on-site tunability makes it ideal for shared spares across slightly different machine variants. Note that this specific SKU lacks a magnet and cannot accept CMSE/DMSE sensors.

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 JSIJ63X150-50 Is Used
Press Fit Tuning
Adjusts the extend end-position by up to 50 mm on-site to dial in the exact insertion depth for light-duty bearing press fits without changing the cylinder.
Variable Transfer Stops
Acts as a retractable lane diverter where the extend stroke can be shortened from 150 mm to 100 mm on the fly to accommodate different package sizes.
Shared Spare Inventory
Serves as a universal replacement cylinder across multiple machines, using the external adjuster to match the specific 100 to 150 mm extend requirement of each station.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X150-50 the Right Cylinder?
The adjustable stroke feature is highly beneficial when you need to tune the extend end-position precisely on-site or want a single spare part to cover several stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a non-magnetized SKU, it cannot host position sensors; you would need the -S variant for CMSE/DMSE switches. For any stroke length at or exceeding 300 mm, always use a external guide to prevent side-load damage to the piston rod.
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 JSIJ63X150-50 FAQ
At 0.7 MPa, the push force is 2182 N and the pull force is 1962 N. The theoretical maximum force is 318 kgf at 1.0 MPa.
The -50 code indicates an external adjuster that allows you to shorten the extend stroke by up to 50 mm on-site, giving a usable extend range of 100 to 150 mm, with the retract end fixed. This mechanism only sets the end position; it does not lock the load. If air pressure is lost, the piston will drift, so you must use an external rod lock or pilot-operated check valve for load holding.
