About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX90-10
The AirTAC SAIJ80X90-10 is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, providing a usable travel window of 80 to 90 mm. It delivers a robust 2513 N push force at 0.5 MPa, making it well-suited for medium-to-heavy handling tasks. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The rear adjustment screw allows you to fine-tune the retract end position at commissioning without adding external stops. Remember that the adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX90-10 Is Used
Machine Setup Tuning
Dial in the exact retract position within the 80-90 mm window during initial commissioning to align tooling perfectly without shimming.
Product Changeover
Quickly adjust the end stop by up to 10 mm when switching between slightly different product sizes on the same production line.
Variable End Stops
Provide a mechanical travel limit for heavy 2513 N push operations where a fixed 90 mm stroke might overrun delicate components.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX90-10 the Right Cylinder?
Choose this 80 mm bore when an application requires around 2513 N of push force at 0.5 MPa. If your task needs less force, stepping down to a 63 mm bore yields 1559 N. The 10 mm adjustment range is ideal for machines that require precise end-position tuning during setup or product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder.
For holding loads safely without continuous air pressure, this cylinder is not sufficient on its own; consider the SAIL or BSAI series, or use an external rod lock. This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. The 25 mm rod and M20x1.5 thread provide excellent rigidity for moderate side loads.
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 SAIJ80BX90-10 FAQ
At 0.5 MPa, this double-acting 80 mm bore cylinder provides a push force of 2513 N and a pull force of 2268 N. It can reach a maximum push force of 4523 N at 0.9 MPa.
The rear adjuster screw lets you shorten the nominal 90 mm stroke by up to 10 mm, creating an 80 to 90 mm usable travel window. It functions as a mechanical stop for end-position tuning, not as a lock to hold the load without air pressure.
