Airtac SAIJ80 Adjustable Cylinder SAIJ80BX400-10
The AirTAC SAIJ80 Adjustable Cylinder SAIJ80BX400-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 400mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX400-10
It features a SUS304 stainless steel rod for superior corrosion resistance and PT tapered ports. By turning the rear screw, you can fine-tune the end position, creating a precise 390-400mm usable travel window without adding external stops.
Because the nominal 400mm stroke is quite long, the 25mm rod and M20x1.5 thread provide robust support, though an external guide is still recommended to manage side loads. This profile cylinder accepts a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX400-10 Is Used
Product Changeovers
Dial in the 390-400mm end position during production line changeovers to accommodate different product sizes without changing the cylinder.
Commissioning Fine-Tune
Trim the stroke by up to 10mm during initial machine setup to perfectly align the tooling without installing external mechanical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX400-10 the Right Cylinder?
The adjustable stroke is ideal for machine setup and product changeovers, allowing you to dial in the exact 390-400mm end position at commissioning rather than swapping out a fixed-stroke SAI cylinder. Remember that the rear adjuster is a stop, not a lock; for load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder.
To match this exact configuration, specify an 80mm bore, 400mm stroke, 10mm adjustment range, PT port thread, and SUS304 rod material. Since the stroke is 400mm, ensure your mounting arrangement includes an external guide to prevent excessive rod side-loading. This unit does not include a magnet, so position sensing via CMSE or DMSE switches is not supported without modification.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ 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 Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ80 Adjustable Cylinder SAIJ80BX400-10 FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw allows you to shorten the effective stroke by up to 10mm, creating a usable travel window of 390-400mm. It functions as a mechanical stop and does not lock the load without continuous air pressure.
