About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX45-10S
The AirTAC SAIJ80X45-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a precise 35 to 45 mm usable travel window. Delivering 2513 N of push force at 0.5 MPa, it is built with an SUS420J2 stainless steel rod (code A) for superior corrosion resistance and carries a PT tapered port thread.
This adjustable-stroke design allows you to fine-tune the retract end position at commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet pairs directly with AirTAC CMSE reed and DMSE electronic solid-state switches for exact position feedback.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX45-10S Is Used
Short-Stroke Pressing
Dials in the exact 35 to 45 mm bottoming position for high-force pressing or forming tasks during initial machine commissioning.
Product Changeover
Quickly adjusts the retract end-stop to accommodate slight variations in workpiece heights without swapping out the entire cylinder.
Sensor-Verified Clamping
Leverages the internal magnet with DMSE electronic sensors to confirm clamp engagement while using the rear screw to set the exact grip depth.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX45-10S the Right Cylinder?
Choose this 80 mm bore when an application requires substantial thrust, such as the 2513 N push force at 0.5 MPa, but stepping down to a 63 mm bore (1559 N push at 0.5 MPa) would be insufficient. The 10 mm adjustment window is ideal for dialing in short, high-force clamping or pressing movements. When specifying an exact ISO 15552 replacement, match the 80 mm bore, 45 mm stroke, PT port thread, -S magnet, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Because the stroke is under 300 mm, side-load stress on the 25 mm rod is naturally minimized, though external guides are still recommended for heavy off-center loads. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true pneumatic locking without pressure, consider the SAIL or BSAI series instead.
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 SAIJ80AX45-10S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, it delivers a peak push force of 513 kgf.
The rear adjuster screw allows you to shorten the nominal 45 mm stroke by up to 10 mm, creating a usable travel window of 35 to 45 mm. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
