Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X150-40S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X150-40S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 150mm 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 JSIJ63X150-40S
The hard-anodized aluminum barrel omits tie rods entirely, yielding a build noticeably shorter and more compact than a same-bore ISO 15552 unit.
With a nominal 150 mm stroke, the usable extend range spans 110 to 150 mm while the retract end remains fixed. This on-site tuning lets you fine-tune the end position without physically swapping the cylinder. The G3/8 port feeds the 29 mm adjustable air cushions at each end. Because the -S suffix denotes a built-in piston magnet, the side grooves readily accept CMSE or DMSE reed and electronic switches for precise position sensing.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 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 JSIJ63X150-40S Is Used
Clamp Position Trimming
Dial in the exact clamping depth on machining fixtures by turning the external adjuster to shorten the extend stroke within the 40 mm window.
Transfer Stopper Tuning
Fine-tune the stopping height of varying product sizes on a transfer line without changing out the entire cylinder assembly.
Vertical Lift Positioning
Lift loads up to 79 kg safely and adjust the upper travel limit on-site to accommodate different pallet heights.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X150-40S the Right Cylinder?
The 40 mm adjustable window is especially useful when you need to dial in a specific end position on the machine or want a single shared spare across slight stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. The included -S magnet supports CMSE/DMSE sensors. For any stroke at or above 300 mm, always use a guide rail to prevent side-load damage to the rod seals.
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 JSIJ63X150-40S FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. The G3/8 port and 29 mm cushions manage the energy.
The external stop screw lets you shorten the extend stroke by up to 40 mm on-site, giving a usable extend range of 110 to 150 mm from the 150 mm nominal maximum. The retract end is fixed. This mechanism sets the end position and does not lock the load; for holding a load on air loss, use an external rod lock or pilot-operated check valve.
