Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X350-30
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X350-30 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 350mm 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 JSIJ63X350-30
The external adjuster allows you to shorten the extend stroke by up to 30 mm, giving a usable range of 320 to 350 mm without swapping the cylinder. Because the nominal 350 mm stroke is the maximum, you can fine-tune the end position precisely where the machine sits. This profile barrel design is noticeably shorter than an equivalent ISO 15552 cylinder of the same bore.
The hard-anodized aluminium body uses a G3/8 port and a 20 mm piston rod. Note this specific SKU lacks a magnet, so it cannot take CMSE or DMSE position sensors. The adjustable air cushions decelerate the piston near the ends, but a plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve for secure load holding.

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 JSIJ63X350-30 Is Used
Stopper Gate Timing
Dial in the exact 320 to 350 mm extend position to halt pallets on a conveyor without re-engineering the hard stops.
Press Pin Depth Tuning
Fine-tune the final 30 mm of the insertion stroke on-site to compensate for material thickness variations.
Shared Spare Inventory
Keep one cylinder in stock and adjust the extend stroke down by 30 mm to cover multiple similar machine setups.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X350-30 the Right Cylinder?
The 30 mm adjustable window is highly useful for sharing a single spare cylinder across several stroke variants or dialing in final end positions on-site. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this is a 350 mm stroke, you must account for side-load risks; always use external guide rails to prevent rod bending. Finally, since this SKU has no -S suffix, it cannot accept magnetic sensors.
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 JSIJ63X350-30 FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. This 63 mm bore model uses a G3/8 air port and features a 29 mm adjustable air cushion at each end.
The -30 code means an external stop screw lets you shorten the extend stroke by up to 30 mm on-site. The nominal 350 mm stroke is the maximum, so the usable extend range is 320 to 350 mm. The retract end remains fixed. This mechanism only sets the end position; it is not a load lock.
