Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X200-75
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X200-75 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 JSIJ63X200-75
The hard-anodized aluminum barrel omits external rods, making the overall body shorter than a same-bore ISO 15552 unit.
The -75 code defines an external adjuster that shortens the extend stroke on site by up to 75 mm. You can tune the usable forward travel anywhere from 125 to the 200 mm maximum without swapping the cylinder, while the retract end remains fixed. An integrated air cushion decelerates the piston near the ends, but a plain unit drifts on air loss; 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 |
| 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 JSIJ63X200-75 Is Used
Press Stroke Tuning
Dial in the exact 125 to 200 mm extend reach on a light stamping or pressing station without machining new hard stops.
Transfer Diverter
Adjust the pusher extension on the fly to accommodate different package widths moving down a packaging line.
Shared Spare Stock
Keep one cylinder in maintenance inventory and shorten its forward travel on site to fit multiple 63 mm machines.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X200-75 the Right Cylinder?
Stepping down to the 50 mm bore drops the 0.5 MPa push force to 982 N, whereas moving up to an 80 mm bore raises it to 2513 N, so the 63 mm size sits in a versatile middle ground. The 75 mm adjuster window is ideal for sharing one spare cylinder across several stroke variants or fine-tuning an end position after a mechanical change. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Because this SKU lacks the -S suffix, it cannot accept a magnetic sensor; choose the -S version for CMSE or DMSE switches. For any stroke at or over 300 mm, always guide the load to prevent rod 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 JSIJ63X200-75 FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. The air port is G3/8.
The nominal stroke is 200 mm, which is the maximum extend travel. The external -75 adjuster lets you shorten that forward stroke on site by up to 75 mm, giving a usable extend range of 125 to 200 mm. The retract end position is fixed.
