Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X150-30
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X150-30 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 JSIJ63X150-30
Its extruded hard-anodized aluminium barrel lacks external tie rods, making the overall body shorter than a same-bore ISO 15552 unit. The G3/8 port matches the bore size, and a 29 mm adjustable air cushion decelerates the piston at each end.
An external stop screw lets you trim the extend stroke by up to 30 mm on site, giving a usable forward range of 120 to 150 mm while the retract end stays fixed. This on-site tuning means you can fine-tune the end position without swapping the cylinder. Note this non-magnetic SKU cannot take a sensor; the -S variant adds a magnet for CMSE/DMSE switches.

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 JSIJ63X150-30 Is Used
Divert Gate Tuning
Trimming the extend stroke 30 mm on-site lets you perfectly set a divert gate contact point without machining new hard stops.
Clamp Positioning
Fine-tune the clamping reach on a machining fixture to accommodate different part thicknesses within the 120 to 150 mm forward range.
Pallet Stopper
Act as an adjustable pallet stop on a transfer line, where the external screw easily compensates for minor conveyor height variations.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X150-30 the Right Cylinder?
The -30 mm adjust window is ideal for sharing a spare across slightly different stroke variants or finalizing end positions during machine commissioning. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this is a non-magnetic model, it cannot accept position sensors; you need the -S version for CMSE/DMSE switches. For any stroke at or over 300 mm, always use a guide rail to prevent rod side-loading and premature seal wear.
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 JSIJ63X150-30 FAQ
At 0.5 MPa it pushes 1559 N and pulls 1402 N. 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.
The nominal 150 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 30 mm on-site, giving a usable forward range of 120 to 150 mm. The retract end is fixed, and this stop only sets position; it does not lock the load.
