Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X80-20S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X80-20S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 80mm 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 JSIJ80X80-20S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder is built for applications that demand exact end-position tuning. The external adjuster allows you to shorten the extend stroke on-site by up to 20 mm, giving a usable extension range of 60-80 mm without swapping the actuator. Its extruded hard-anodized aluminum barrel is noticeably more compact than a same-bore ISO 15552 unit. The integrated -S piston magnet supports CMSE/DMSE sensors in the side grooves for precise position feedback.
This double-acting single-rod actuator handles about 1508 N of real work safely, which is roughly 128 kg lifted vertically with a 2:1 margin. It features a 25 mm rod, a G3/8 port, and 29 mm adjustable air cushions at both ends. The stop screw sets the extend end position but does not lock the load; you will 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 JSIJ80X80-20S Is Used
Press Fit Tuning
Allows operators to dial in the exact 60-80 mm extend stop for seating bearings without changing the physical cylinder setup.
Variable Length Diverter
Adjusts the extend stroke on-site to deflect different package sizes on a packaging line while maintaining compact JIS dimensions.
Vertical Lift Stop
Sets a precise upper travel limit for a 128 kg vertical lift platform, using the external screw to fine-tune the endpoint safely.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X80-20S the Right Cylinder?
Size this 80 mm bore against the neighboring 63 mm and 100 mm options. The 63 mm provides 1559 N push at 0.5 MPa, while the 100 mm yields 3927 N, so the 80 mm at 2513 N is ideal for medium-heavy loads. The -20 mm adjustable window is perfect when you need to fine-tune the extend endpoint on-site or want a single spare part that covers slight stroke variations. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The -S suffix means a magnet is already built in for CMSE/DMSE switches. For any stroke at or above 300 mm, 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 JSIJ80X80-20S FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull. At 0.7 MPa it delivers 3518 N push and 3175 N pull. The theoretical maximum force is 513 kgf at 1.0 MPa. This 80 mm bore cylinder uses a G3/8 air port and a 25 mm piston rod.
The nominal 80 mm stroke is the maximum extension. An external stop screw lets you shorten the extend stroke on-site by up to 20 mm, giving a usable range of 60-80 mm. The retract end remains fixed. This mechanism only sets the end position and does not lock the load.
