Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X500-30S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X500-30S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 500mm 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 JSIJ63X500-30S
The external stop screw lets you shorten the extend stroke by up to 30 mm, giving a usable range of 470-500 mm without swapping the actuator. Its extruded hard-anodized aluminum barrel makes it shorter and more compact than a same-bore ISO 15552 unit. The -S suffix adds a piston magnet for CMSE/DMSE sensors in the side grooves.
The G3/8 port and M18x1.5 rod thread match the 63 mm bore class, while 29 mm adjustable air cushions decelerate the payload at both ends. Remember that the cushion only slows the piston; you need an external rod lock or pilot-operated check valve to hold a load securely on air loss.

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 JSIJ63X500-30S Is Used
Transfer Line Diverter
Fine-tune the 470-500 mm extend position to match varying product widths on the fly without machining new hard stops.
Clamping Station Setup
Dial in the exact clamping reach within the 30 mm window during commissioning to accommodate different fixture heights.
Vertical Lift Gate
Lifts loads up to 79 kg safely, using the adjustable stroke to set precise gate open heights for specific pallet sizes.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X500-30S the Right Cylinder?
The 30 mm adjustable window is ideal for sharing one spare across multiple stroke variants or fine-tuning a fixture position on the fly. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the 500 mm stroke is long, always support the load with external guides to prevent rod bending and side-load wear. The built-in magnet supports CMSE/DMSE switches for position confirmation.
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 JSIJ63X500-30S FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. It uses a G3/8 port and operates at speeds between 30-800 mm/s.
The nominal stroke is 500 mm, which is the maximum extend length. An external stop screw lets you shorten the extend stroke on-site by up to 30 mm, yielding a usable range of 470-500 mm. The retract end is fixed, and this mechanism sets the end position rather than locking the load.
