Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X100-50
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X100-50 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 100mm 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 JSIJ63X100-50
Its extruded hard-anodized aluminium barrel makes it shorter and more compact than a same-bore ISO 15552 unit. The G3/8 ported body carries a 20 mm rod and adjustable air cushions at both ends.
The -50 code means an external stop screw lets you shorten the extend stroke on-site by up to 50 mm. You get a usable extend range of 50 to 100 mm without changing the cylinder, while the retract end stays fixed. This plain SKU lacks a magnet and cannot take a sensor; add the -S variant for CMSE/DMSE switches.

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

| 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 JSIJ63X100-50 Is Used
Press Fit Tuning
Fine-tune the 50 to 100 mm extend stroke on-site to set exact pressing depth for bearing insertion without swapping cylinders.
Variable Diverter
Adjust the external stop screw to change the push distance for routing different package sizes on a packaging line.
Shared Spare Stock
Keep one 100 mm nominal cylinder as a universal spare, shortening the extend stroke up to 50 mm to fit multiple machines.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X100-50 the Right Cylinder?
The JSIJ series supports Basic, FA, LB, TC, TCM1 and TCM2 mounts. The adjustable stroke is ideal for sharing one spare across stroke variants or fine-tuning end positions on-site. Because this is a no-magnet SKU, you cannot fit position sensors. For any stroke over 300 mm, guide the load to prevent side-load wear on the 20 mm rod seal.
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 JSIJ63X100-50 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 force is 318 kgf at 1.0 MPa. It uses a G3/8 port and a 20 mm rod.
The external stop screw lets you shorten the extend stroke by up to 50 mm on-site, giving a usable extend range of 50 to 100 mm. The nominal 100 mm stroke is the maximum. The retract end is fixed. This stop sets the end position and is not a load lock.
