About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX45-10
The AirTAC SAIJ80X45-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 25 mm rod and G3/8 ports, yielding a robust 2513 N push force at 0.5 MPa. By turning the rear screw, you achieve a usable travel window of 35-45 mm, enabling exact end-position tuning without swapping hardware.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning position sensing requires adding a magnet or external switches. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX45-10 Is Used
Short-Stroke Clamping
Dial in the exact 35-45 mm clamping depth on machined parts, compensating for material thickness variations without repositioning the cylinder body.
Product Changeover
Quickly adjust the end-stop by up to 10 mm during production line format changes, allowing rapid shifts between different product sizes.
Assembly Pressing
Leverage the 2513 N push force at 0.5 MPa for light pressing and seating tasks, using the rear screw to prevent over-travel and damage.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX45-10 the Right Cylinder?
Select this 80 mm bore when an application requires higher thrust than a 63 mm cylinder (which provides 1559 N push at 0.5 MPa) but still needs compact travel. The 10 mm adjustment range is ideal for fine-tuning short-stroke movements during machine commissioning or product changeover, avoiding the need to bolt on external stops. To replace this cylinder, match the 80 mm bore, 45 mm stroke, PT port threads, and the chosen mounting hardware.
Because the stroke is under 300 mm, side-load stress on the 25 mm rod is minimal, though external guides remain recommended for heavy lateral loads. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for pilot-operated locking, consider the SAIL or BSAI series.
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 SAIJ80AX45-10 FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder generates a push force of 2513 N and a pull force of 2268 N. At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw allows you to trim the effective stroke by up to 10 mm. This creates a usable travel window of 35-45 mm from the 45 mm nominal stroke, enabling precise end-position tuning at commissioning without replacing the cylinder.
