Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X200-50
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X200-50 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 JSIJ63X200-50
Its extruded hard-anodized aluminium barrel is noticeably shorter than a same-bore ISO 15552 unit, saving valuable machine space without losing strength. The G3/8 port matches the bore size for efficient air flow.
The external adjuster lets you shorten the extend stroke on-site by up to 50 mm, giving a usable range of 150 to 200 mm while the retract end stays fixed. This on-site tuning means you can fine-tune the end position without swapping the cylinder. Note that this plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

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 JSIJ63X200-50 Is Used
End-Position Trimming
Dial in the exact extend stop on a clamping fixture by shortening the stroke up to 50 mm without changing the cylinder mount.
Shared Spare Inventory
Use the 50 mm adjustment window to cover multiple slightly different stroke requirements on the floor with one replacement unit.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X200-50 the Right Cylinder?
The 50 mm adjuster window is ideal for sharing a single spare cylinder across several stroke variants or dialing in a final end position on-site. You can mount it using FA, LB, TC, TCM1, or TCM2 brackets. Since this is a non-magnet SKU, you must select an -S variant if you need position sensing. For any stroke reaching 300 mm or more, always guide the load to prevent side-load damage.
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 JSIJ63X200-50 FAQ
This 63 mm bore cylinder pushes 1559 N and pulls 1402 N at 0.5 MPa. 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 features a 29 mm adjustable air cushion at each end.
The nominal 200 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 50 mm, yielding a usable range of 150 to 200 mm. The retract end is fixed. This mechanism only sets the end position; it does not lock the load, so you need an external rod lock or pilot-operated check valve to hold a load on air loss.
