About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX150-75
The AirTAC SAIJ80X150-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 75 to 150 mm, allowing you to dial back the nominal 150 mm stroke by up to 75 mm during commissioning without adding external stops.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads for a robust pneumatic connection. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a travel stop to set end positions and deceleration, meaning it will not hold a 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 SAIJ80BX150-75 Is Used
Product Changeover
Quickly reposition the retract end-stop on packaging lines when switching to different container sizes, utilizing the 75 mm adjustment range to avoid physical hardware swaps.
Commissioning Calibration
Fine-tune the final resting position of a clamping mechanism during machine setup, dialing in the exact travel distance within the 75-150 mm window to perfect the process.
Variable End-Stops
Provide adaptable retraction limits on automated assembly stations where multiple part configurations require different stroke depths from a single actuator.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX150-75 the Right Cylinder?
Choose this 80 mm bore when your application requires more thrust than a 63 mm cylinder (which provides 1559 N at 0.5 MPa) but less bulk than a 100 mm unit. The 75 mm adjustment range is ideal for machines running multiple product sizes, letting operators fine-tune the retract end-position on the fly instead of swapping hardware. For load-holding requirements without continuous air pressure, select a SAIL or BSAI series cylinder instead, as the SAIJ adjuster is not a mechanical lock.
To match this ISO 15552 interchangeable cylinder for a replacement, verify the 80 mm bore, 150 mm stroke, 75 mm adjuster, PT G3/8 port, and standard mounting interface (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 150 mm, ensure your mounting configuration supports the rod adequately to prevent excessive side-loading on the piston.
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 SAIJ80BX150-75 FAQ
The rear adjuster screw acts as a mechanical stop that trims the effective travel. For this model, you can shorten the 150 mm stroke down to as little as 75 mm, creating a 75-150 mm usable window for precise end-position tuning.
