Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X150-20
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X150-20 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 JSIJ63X150-20
The hard-anodized aluminum barrel leaves out external rods, making the overall body shorter than a same-bore ISO 15552 unit. A G3/8 port feeds the chamber, while adjustable air cushions of 29 mm absorb impact at both ends.
The external stop screw provides a 20 mm on-site extend-shortening window, letting you dial the usable forward stroke down from the 150 mm maximum to 130 mm without swapping parts. This fine-tunes the end position perfectly for shared spares across stroke variants.

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 JSIJ63X150-20 Is Used
Stroke Tuning for Forming Presses
Dial in the exact material contact depth on-site using the 20 mm window, avoiding cylinder swaps when product thickness changes.
Adjustable Package Diverters
Fine-tune the pusher extension length on the fly to handle varying carton widths without repositioning the entire mount.
Shared Spare for Pallet Stops
Keep one cylinder in stock and adjust the forward stop from 150 mm down to 130 mm to fit different pallet sizes on the line.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X150-20 the Right Cylinder?
The JSIJ series supports Basic, FA, LB, TC, TCM1, and TCM2 mounts. The 20 mm adjuster is ideal when you need to unify spares across slightly different stroke lengths. Because this is a non-magnet SKU, it cannot accept CMSE or DMSE sensors; choose the -S variant if you need position detection. For any stroke at or over 300 mm, 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 JSIJ63X150-20 FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa.
The 150 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 20 mm on-site, giving a usable range of 130 to 150 mm. The retract end remains fixed, and this stop only sets position; it does not lock the load.
