About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX155-10S
The AirTAC SAIJ80X155-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position during commissioning. With a nominal 155 mm stroke and a 10 mm adjustment range, it provides a usable travel window of 145 to 155 mm without needing external stops.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for use with CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the G3/8 port ensures adequate airflow for its 30-800 mm/s speed range. The rear adjuster acts purely as a mechanical stop for travel tuning 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 SAIJ80BX155-10S Is Used
Machine Changeover
Dial in the 145-155 mm travel window during product size transitions to set new end stops without swapping the cylinder.
End-Position Tuning
Fine-tune the retract stroke by up to 10 mm at commissioning to perfect mechanical stops without adding external hardware.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX155-10S the Right Cylinder?
Choose this SAIJ80X155-10-S when an 80 mm bore is required to handle loads up to 2513 N at 0.5 MPa, and a precise 145-155 mm travel window is needed for product changeovers. If your application requires less force, stepping down to a 63 mm bore yields 1559 N. The adjustable stroke is ideal for dialing in final end positions on the fly, whereas a fixed SAI cylinder locks you into one exact dimension. For holding loads safely without live air, consider an SAIL or BSAI cylinder instead, as the adjuster here is not a lock. This model uses a PT tapered G3/8 port and supports mountings Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80BX155-10S FAQ
It features a rear adjusting screw that lets you mechanically shorten the nominal 155 mm stroke by up to 10 mm, creating a usable travel window of 145 to 155 mm. The adjuster acts as a travel stop and does not lock or hold the load without continuous air pressure.
