Airtac SAIJ80 Adjustable Cylinder SAIJ80BX150-75S
The AirTAC SAIJ80 Adjustable Cylinder SAIJ80BX150-75S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 150mm 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 SAIJ80BX150-75S
The AirTAC SAIJ80X150-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 75 to 150 mm. The extruded aluminum barrel features sensor grooves on both sides, and this -S variant includes a magnet for direct switching via CMSE reed or DMSE solid-state sensors.
This unit uses a SUS304 stainless steel rod for superior corrosion resistance and carries a PT tapered port thread. The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract end position without adding external stops. It is not a locking device; for load-holding without live air pressure, consider the SAIL or BSAI series.

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 SAIJ80BX150-75S Is Used
Changeover Adjustment
Dial in the 75 to 150 mm retract distance during product size changeovers without swapping the cylinder or bolting on external stopper blocks.
Sensor Positioning
Leverage the integrated magnet with DMSE solid-state sensors to confirm end-of-stroke travel within the tuned adjustment window.
End-Stop Tuning
Fine-tune the exact retract position during machine commissioning using the rear stopper screw to perfect the mechanical timing.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX150-75S the Right Cylinder?
The 75 mm adjustment range is ideal for product changeovers requiring significantly different retract distances on the same tooling. Since the stroke is 150 mm, the 25 mm rod and M20x1.5 thread handle side loads well, though any long unsupported travel still needs an external guide.
For ISO 15552 interchangeability, match the 80 mm bore, 150 mm stroke, 75 mm adjustment, PT ports, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. The rear adjuster and variable air cushions only decelerate the load; they do not hold it without live air.
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 SAIJ80BX150-75S FAQ
The rear adjuster screw lets you shorten the effective stroke from 150 mm down to 75 mm. This creates a 75 to 150 mm travel window for fine-tuning end positions at commissioning, but the screw acts only as a stop and does not lock the load without live air.
