Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X275-30
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X275-30 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 275mm 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 JSIJ63X275-30
The hard-anodized aluminum barrel leaves out external rods entirely, making the overall body shorter and more compact than a same-bore ISO 15552 unit.
The -30 code defines the extend-shortening window, allowing you to fine-tune the end position anywhere between 245 mm and 275 mm without swapping the actuator. Because this SKU lacks a magnet, it cannot take a CMSE or DMSE sensor. Note that the adjustable stop sets the end position but does not lock the load; the 29 mm air cushions only decelerate the piston near the ends.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|

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 JSIJ63X275-30 Is Used
Adjustable Clamping Press
Dial in the exact 245 to 275 mm extend position on-site to clamp varying material thicknesses without re-engineering the fixture.
Transfer Diverter Gate
Fine-tune the actuator end-stop to route different package sizes accurately on a packaging line using the 30 mm adjustment window.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X275-30 the Right Cylinder?
For context, the 50 mm bore pushes 982 N at 0.5 MPa, while the 80 mm bore pushes 2513 N, placing this 63 mm actuator right in the mid-range. The on-site extend adjustment is ideal when you need to share a spare across stroke variants or dial in a final end position after mechanical assembly. Mounting options include FA, LB, TC, TCM1, and TCM2. As this is a non-magnet SKU, you cannot fit position sensors; choose an -S variant for CMSE/DMSE switches. For a 275 mm stroke, ensure adequate side-load guidance to prevent rod bearing wear. For holding a load on air loss, add an external rod lock or pilot-operated check valve.
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 JSIJ63X275-30 FAQ
This 63 mm bore cylinder pushes 1559 N and pulls 1402 N at 0.5 MPa. 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 and an M18x1.5 rod thread.
The -30 means the 275 mm nominal extend stroke can be shortened by up to 30 mm on-site, giving a usable range of 245 to 275 mm. An external stop screw sets the end position, while the retract end remains fixed. This mechanism is for position tuning only and does not hold the load on air loss.
