About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX450-100S
The AirTAC SAIJ80X450-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 350 to 450 mm without swapping out the unit. The extruded aluminum barrel includes sensor grooves on both sides for straightforward switch mounting.
This specific SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G3/8 connection. Because it carries the -S magnet option, it directly supports AirTAC CMSE reed and DMSE electronic solid-state sensors. The rear adjuster acts purely as a mechanical stop for end-position tuning and does not lock 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 SAIJ80BX450-100S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 350 and 450 mm during machine commissioning to accommodate different material lengths without changing hardware.
Product Line Changeover
Quickly adjust the rear stopper on the fly when switching a production line to a new package size, saving downtime compared to replacing fixed-stroke cylinders.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX450-100S the Right Cylinder?
Select this 80 mm bore cylinder when an application requires substantial thrust, as stepping down to a 63 mm bore drops the push force to 1559 N at 0.5 MPa. The 100 mm adjustment range is ideal for machine changeovers where product sizes vary, eliminating the need to physically bolt on external stops or buy multiple fixed-stroke SAI cylinders. For load-holding requirements without continuous air pressure, this standard adjuster is insufficient; you should instead look at the SAIL air-released lock or BSAI clamp-lock series.
Because the 450 mm stroke is relatively long, the 25 mm rod diameter and M20x1.5 rod thread provide necessary rigidity, but an external guide is still recommended to prevent side-loading damage. This SAIJ model shares the standard ISO 15552 mounting interface and supports a reduced set of mounting accessories: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It deliberately omits FB, CA, CB, and CR mounts. Operating speed is rated for 30-800 mm/s.
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 SAIJ80BX450-100S FAQ
If pressure is increased to 0.9 MPa, the push force reaches 4523 N.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 450 mm down by up to 100 mm, creating a 350 to 450 mm usable window. It only sets the end position and does not function as a brake or lock.
