Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-30S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-30S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 800mm 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 JSIJ80X800-30S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder features an external adjuster that lets you shorten the extend stroke on-site by up to 30 mm. The nominal 800 mm stroke remains the maximum travel, giving you a usable extend window of 770 to 800 mm for fine-tuning the end position without swapping the actuator. This unit handles about 1508 N of real work safely, which translates to lifting roughly 128 kg vertically with a 2:1 margin.
Built with an extruded hard-anodized aluminum barrel, the body is noticeably shorter and more compact than a same-bore ISO 15552 cylinder. It uses a G3/8 port and includes a built-in piston magnet for CMSE/DMSE sensors. Remember that the adjustable stop sets the end position but does not lock the load; you need an external rod lock or pilot-operated check valve to hold a load securely against air loss.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-30S Is Used
Long-Reach Diverting
Tunes the 800 mm extend position precisely on-site to align with moving pallets without remounting the actuator.
High-Bay Pusher
Uses the 30 mm adjustment window to compensate for rack deflection over long travel distances in storage systems.
Large-Part Ejection
Dials in the exact ejection point on a long press bed, leveraging the 2513 N push force to clear heavy parts.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-30S the Right Cylinder?
When sizing this 80 mm bore, stepping down to a 63 mm bore yields 1559 N push at 0.5 MPa, while stepping up to a 100 mm bore provides 3927 N. The 30 mm adjustable window is ideal for sharing a spare across stroke variants or dialing in final end positions on-site. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the 800 mm stroke is long, always use external guides to prevent rod bending and manage side loads. The -S suffix means a magnet is present for CMSE/DMSE switches.
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 JSIJ80X800-30S FAQ
At 0.5 MPa it pushes 2513 N and pulls 2268 N. At 0.7 MPa it pushes 3518 N and pulls 3175 N. The theoretical maximum force is 513 kgf at 1.0 MPa. This 80 mm bore cylinder uses a G3/8 port and features a 25 mm rod with an M22x1.5 thread.
The external adjuster allows you to shorten the extend stroke by up to 30 mm on-site. The nominal 800 mm stroke is the maximum travel, yielding a usable extend range of 770 to 800 mm. The retract end remains fixed, and the stop mechanism only sets the end position rather than locking the load.
