Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-40S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-40S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm 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 JSIJ80X275-40S
Generating 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings heavy-duty actuation into a compact footprint. The hard-anodized aluminium barrel makes it shorter than a same-bore ISO 15552 unit. A built-in magnet (-S) allows CMSE or DMSE switches to drop directly into the side grooves for position sensing. With a practical safe working load of about 1508 N, it handles roughly 128 kg lifted vertically.
The -40 code means an external stop screw lets you shorten the extend stroke on-site by up to 40 mm, giving a usable range of 235-275 mm. You fine-tune the end position without physically swapping the cylinder, while the retract end remains fixed. Air connects via a G3/8 port, and adjustable cushions decelerate the load at both ends. Note that a plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve if you need to hold a load securely.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-40S Is Used
Press Stroke Tuning
Dial in the exact 235-275 mm extend position on-site using the external adjuster to accommodate varying material thicknesses without changing the cylinder.
Divertor Gate Actuation
Leverage the 1508 N safe working load to push heavy divertor gates, using the built-in magnet and DMSE switches to confirm gate position.
Pallet Stopper Adjustment
Fine-tune the stopping point for different pallet sizes by shortening the extend stroke up to 40 mm, keeping the retract position fixed.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-40S the Right Cylinder?
When sizing, stepping down to a 63 mm bore drops the 0.5 MPa push force to 1559 N, while stepping up to 100 mm raises it to 3927 N. The 80 mm bore sits comfortably in the middle for medium-heavy work. The adjustable-stroke window is ideal when you need to share one spare across slight stroke variants or dial in a precise end position on the machine. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. The -S suffix ensures you have the magnet for CMSE/DMSE sensors. Because the 275 mm stroke exceeds 300 mm, ensure adequate side-load guidance to prevent premature seal wear.
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 JSIJ80X275-40S FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull. At 0.7 MPa it provides 3518 N push and 3175 N pull. The theoretical maximum force is 513 kgf at 1.0 MPa. The air port size is G3/8.
The 275 mm nominal stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 40 mm, yielding a usable extend range of 235-275 mm. This sets the end position but does not lock the load.
