Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X160-75
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X160-75 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 160mm 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 JSIJ63X160-75
It is a JIS-standard profile cylinder that is physically shorter and more compact than a same-bore ISO 15552 unit, built with a hard-anodized aluminum extruded barrel. The external adjuster allows you to shorten the extend stroke by up to 75 mm right at the machine, meaning the 160 mm nominal stroke can be fine-tuned down to an 85 mm usable length without swapping the cylinder.
This adjustability makes it ideal for sharing a single spare across multiple stroke variants or dialing in a precise end position. The unit features a G3/8 port, an M18x1.5 rod thread, and 29 mm adjustable air cushions at both ends. Note that this specific SKU lacks a magnet and cannot accept CMSE or DMSE sensors; adding the -S variant enables switch readiness. Furthermore, the cushion only decelerates the piston near stroke end, so an external rod lock or pilot-operated check valve is required to hold a load securely.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |

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 JSIJ63X160-75 Is Used
End-Position Tuning
Dial in the exact extend stop on a machining fixture by shortening the 160 mm stroke up to 75 mm on-site without changing the cylinder mount.
Variable Transfer Push
Adjust the push-off distance for different product sizes on a packaging line by setting the external stop screw between 85 mm and 160 mm.
Shared Spare Inventory
Keep one actuator in stock for multiple machines by using the adjuster to match various shorter stroke requirements on the factory floor.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X160-75 the Right Cylinder?
The 75 mm adjustable window is particularly useful when you need to tune the extend end position on-site or want a shared spare across slightly different stroke lengths. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this is a non-magnetized SKU, it cannot support position sensing; choose the -S version if you need CMSE or DMSE switches. For any stroke length of 300 mm or longer, always use a guide rail to prevent side-load damage to the piston rod.
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 JSIJ63X160-75 FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa.
The external stop screw lets you shorten the extend stroke by up to 75 mm on-site. The nominal 160 mm stroke is the maximum, giving you a usable extend range of 85 mm to 160 mm. The retract end remains fixed, and the stop screw only sets the end position, acting as a cushion rather than a load lock.
