Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X300-100S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X300-100S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 300mm 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 JSIJ63X300-100S
The external adjuster lets you shorten the forward stroke by up to 100 mm on the fly, meaning the 300 mm nominal length serves as a maximum and the retract end remains fixed. Built as a JIS-standard profile cylinder, its hard-anodized aluminium barrel makes it shorter and more compact than a same-bore ISO 15552 unit.
Because this is the -S variant, a built-in piston magnet lets you drop CMSE or DMSE reed and electronic switches directly into the side grooves for precise position sensing. Pneumatic connections use a G3/8 port, while a 29 mm adjustable air cushion at each end decelerates the piston smoothly. Note that the cushion only softens the end-of-stroke impact; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended load.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |

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 JSIJ63X300-100S Is Used
Divert Gate Tuning
Dial in the exact extend reach of a sorting diverter on-site by shortening the stroke up to 100 mm, ensuring packages hit the correct lane without re-mounting hardware.
Press Stroke Adjustment
Alter the pressing depth of a light-duty assembly station on the fly, using the external stop screw to shift the forward end position for different product heights.
Variable Lift Stops
Raise goods to varying tier heights in a compact stacking cell, relying on the -S magnet to confirm the intermediate extend positions triggered by the adjuster.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X300-100S the Right Cylinder?
The -100 mm adjuster is ideal when you need to fine-tune the extend end position without swapping the cylinder, or when you want a shared spare across multiple stroke variants. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Since the 300 mm stroke is fairly long, always support the load with an external guide to prevent rod bending and excessive side loading.
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 JSIJ63X300-100S FAQ
At 0.5 MPa it pushes 1559 N and pulls 1402 N. At 0.7 MPa the push is 2182 N and pull is 1962 N. The theoretical maximum force is 318 kgf at 1.0 MPa. It uses a G3/8 port and features a 20 mm rod with an M18x1.5 thread.
The 300 mm nominal stroke is the maximum forward travel. The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, giving a usable extend range of 200 to 300 mm. The retract end is fixed, and this stop mechanism only sets the end position—it is not a load lock.
