Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X400-75S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X400-75S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 400mm 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 JSIJ80X400-75S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings compact power to pneumatic setups. The hard-anodized aluminum barrel leaves external tie rods out of the design entirely, making the overall body shorter than a same-bore ISO 15552 unit. It handles about 1508 N of real work safely, which translates to lifting roughly 128 kg vertically with a 2:1 margin.
The external stop screw provides a 75 mm adjustment window, letting you trim the extend stroke down from the 400 mm maximum to 325 mm directly on-site without swapping the cylinder. Air connects via a G3/8 port, and the -S suffix means a built-in magnet is ready for CMSE or DMSE sensors in the side grooves. A 29 mm adjustable air cushion at each end manages deceleration, though an external rod lock is required if you need to hold a load during air loss.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X400-75S Is Used
Reject Diverter Tuning
Dial in the exact push distance for moving mixed-size cartons off a main belt by trimming the 75 mm extend window on-site.
Pallet Stop Adjustment
Set a precise end-stop position for varying pallet depths without disassembling the line or changing the cylinder body.
Press End-Position Set
Fine-tune the downward extend stroke on a light assembly press to accommodate different product stack heights.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X400-75S the Right Cylinder?
When sizing this 80 mm bore, the neighboring 63 mm option yields 1559 N push at 0.5 MPa, while stepping up to the 100 mm bore provides 3927 N, giving you clear boundaries for your force requirements. The 75 mm extend-shortening window is highly useful for dialing in precise end positions on-site or sharing a single spare cylinder across multiple stroke variants. You can mount it using FA, LB, TC, TCM1, or TCM2 brackets. Because the 400 mm stroke creates leverage, always support the rod against side-load bending with an external guide rail.
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 JSIJ80X400-75S FAQ
This 80 mm bore cylinder uses a G3/8 port and a 25 mm piston rod. It generates 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push and 3175 N pull at 0.7 MPa, with a theoretical maximum of 513 kgf at 1.0 MPa.
The 400 mm nominal stroke is the maximum extend length. An external stop screw lets you shorten the extend stroke by up to 75 mm on-site, giving a usable range of 325-400 mm. The retract end remains fixed, and this mechanism sets end position rather than locking the load.
