About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX95-40
The AirTAC SAIJ80X95-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 55 to 95 mm, allowing you to dial back the 95 mm nominal stroke by up to 40 mm during commissioning. With a 25 mm piston rod and a robust 4523N thrust at 0.9 MPa, it handles heavy dynamic loads while maintaining dimensional interchangeability with standard ISO 15552 mounting interfaces.
This SKU is configured with a SUS420J2 stainless steel rod for superior corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. The rear adjuster acts purely as a travel stop to fine-tune end positions without adding external stops, while the variable air cushions at both ends manage deceleration.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX95-40 Is Used
Product Changeovers
Quickly adapt end-stops for varying product lengths on a packaging line without physically replacing the cylinder.
Commissioning Calibration
Fine-tune the 55-95 mm travel window during machine setup to perfect positioning without external stoppers.
Heavy Assembly Pressing
Leverage the 4523N thrust at 0.9 MPa for robust pressing operations while using the adjuster to set precise depth.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX95-40 the Right Cylinder?
Choose this 80 mm bore when your application requires substantial force, delivering 2513N push and 2268N pull at 0.5 MPa. If your setup needs less force, step down to the 63 mm bore which provides 1559N push at 0.5 MPa. The 40 mm adjustment range is highly beneficial for product size changeovers on a production line, letting you set variable end-stops on the fly rather than swapping out a fixed-stroke SAI cylinder.
For ISO 15552 replacement matching, verify the 80 mm bore, 95 mm stroke, 40 mm adjustment, PT G3/8 port, and your preferred mounting style from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Remember that the rear adjuster is a stop, not a lock; it will not hold a load without live air pressure. For true load-holding without continuous air, consider the SAIL or BSAI series. Because the stroke is under 300 mm, side-load risks are lower, but an external guide is still recommended for heavy lateral 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 SAIJ80AX95-40 FAQ
The rear adjuster acts as an external stopper that lets you shorten the effective travel from 95 mm down to 55 mm. This provides a 40 mm tuning window for precise end-position setup without changing the cylinder.
At 0.5 MPa, it provides 2513N of push force and 2268N of pull force. At 0.9 MPa, the push force increases to 4523N.
